RE: Unable to integrate Apache 2.0.24, mod_jk2 with Tomcat 5.

[Andy Eastham]

Joao,

The way I do this is to forward all of a subdirectories requests to a webapp
on tomcat, and then I give my servlets an arbitrary extension (I use .isa
for irrelevant reasons).

For example, in workers2.properties, I forward everything to the apache url
/control to tomcat:
[uri:localhost/control/*]
worker=ajp13:localhost:8009

[uri:wwws/control/]
worker=ajp13:localhost:8009

[uri:127.0.0.1/control/*]
worker=ajp13:localhost:8009

Then in tomcats server.xml:
 Host name=xxx.xx.xxx.xx.xx debug=0 appBase=webapps
unpackWARs=true autoDeploy=true
 Aliaswww.xxx.com/Alias
 Alias192.168.0.102/Alias
 Aliaslocalhost/Alias
 Aliaswwws/Alias
 Alias127.0.0.1/Alias


 Context path=control docBase=
debug=1/

 Valve
className=org.apache.catalina.valves.AccessLogValve
 directory=logs  prefix=home_access_log. suffix=.txt
 pattern=common resolveHosts=false/
/Host

Note the context path for control, and the aliases for different urls your
server may be called by.

Then in the web.xml for the control webapp (under WEB-INF directory):
servlet
servlet-name
myServlet
/servlet-name
servlet-class
com..servlet.myServlet
/servlet-class
load-on-startup1/load-on-startup
/servlet


servlet-mapping
servlet-name
myServlet
/servlet-name
url-pattern
*.isa
/url-pattern
/servlet-mapping

This maps any requests to anything.isa to my servlet.

If you don't want to use the extension method, you can use the invoker
servlet supplied with Tomcat.

This method requires that you redirect a subdirectory, not all apache
requests.  I don't know if you can redirect all apache requests, but that
would lose some of the benefits of using apache with tomcat, eg serving
images and other static content directly from apache.

Hope this helps,

Andy

 Hello,
 
 Thank's to Andy Eastham solution I managed to get Apache to forward *.jsp

 that I had to define localhost(127.0.0.1) in JK2.properties file as
 without this config Tomcat(JK2) was listening on the wrong

 Servlets are still not being forwarded - Apache reports - 404 file not

 MyServlet exists on my root_path as MyServlet.class . Can anyone tell me

 WARNING: Reinitializing ServerSocket
 
 I realize that increasing file descriptor limit per process could help a
 bit, but my system administrator simply doesn't want to do that (since it
 requires restart).
 
 Now, the problem is how to avoid too many open files exception. Any
 suggestions regarding Tomcat (or Apache) configuration, coding practice,
 some runtime operating system parameters would be greatly appreciated.
 
 Here's my configuration:
 
 Default Solaris 8 (I believe) installation on 2CPU+4GB RAM box. TCP
 connection wait timeout (I believe that the correct wording) is decreased
 from 240sec to 60sec and that's the only parameter changed on Solaris.
 
 Tomcat 4.1.30 with j2sdk 1.4.2_04 (server mode) with Apache 2.0 as a
 proxy.
 Every single request goes through Apache which then routes it to Tomcat.
 600.000 hits and cca 3GB of data daily, with peaks during working hours,
 of
 course, about 50.000 hits per hour. The delivered content consists mostly
 of small images (3-20k) delivered directly from a database (servlet sets
 content type etc, img src=/preview?id=123 style)
 
 Application lives about 24hours and then dies with the exception shown
 above. As far as I can see, all input- and output- streams are flushed and
 closed, at least in my application. Cannot guarantee for the underlining
 libraries.
 
 Somehow I think that I cannot squeeze the application anymore and that
 we're
 hitting tomcat+solaris limit.
 
 Ahm... whoever managed to completelly read this rather long post I hope
 will
 have some suggestions.
 
 Thanks in advance!
 
 Cheers,
 Davor

RE: Repost... no response from numerous posts

[Andy Eastham]

Jack,

I think what you are looking for is the following set of directives:

In httpd.conf, in the Virtual Host section something like the following:
Location /control/
JkUriSet worker ajp13:localhost:8009
/Location
Location /wwwsadmin/
JkUriSet worker ajp13:localhost:8009
/Location

Then in workers2.properties:
# define the worker
[ajp13:localhost:8009]
channel=channel.socket:localhost:8009

# Uri mapping
[uri:192.168.0.102/control/*]
worker=ajp13:localhost:8009

[uri:external.host.name/control/*]
worker=ajp13:localhost:8009

[uri:localhost/control/*]
worker=ajp13:localhost:8009

[uri:internal.host.name/control/]
worker=ajp13:localhost:8009

[uri:127.0.0.1/control/*]
worker=ajp13:localhost:8009

[uri:192.168.0.102/wwwsadmin/*]
worker=ajp13:localhost:8009

[uri:localhost/wwwsadmin/*]
worker=ajp13:localhost:8009

[uri: external.host.name /wwwsadmin/]
worker=ajp13:localhost:8009

[uri:internal.host.name/wwwsadmin/]
worker=ajp13:localhost:8009

[uri:127.0.0.1/wwwsadmin/*]
worker=ajp13:localhost:8009

You may not need all the variations of name and IP address in
workers2.properties, but I've added them all in and it works...

Also, I've just noticed that on my laptop, I've only got the
workers2.properties file and settings, not the Location directives in
httpd.conf, and that seems to work too.  However, the above is taken from a
production Solaris 9 server.

  I've posted this same question on the apache and tomcat lists for the
  past six weeks and gotten no answers.  Not even an insult saying the
  question was stupid.  If I could find the answer in the docs I wouldn't
  be asking.
 
  I have virtual host in apache 2.0.49 with mod_jk2 its DocumentRoot is
  domain.com it has a subdirectory called members (i.e.
  domain.com/members) that has an html doc with links to three different
  tomcat apps.  (i.e. domain.com/members/index.html with a link of
  http://www.domain.com/members/minutes/index.jsp).
 
  On the tomcat 5.0.24 side I have a minutes webapp (minutes.war) in the
  default context (i.e. $TOMCAT_HOME/webapps/minutes.war) and deploys
  under the directory minutes.  (The members directory does not exist on
  the tomcat side).
 
  How do you map the apache path of
  http://www.domain.com/members/minutes/index.jsp to the tomcat minutes
  app?
 
  In the past using both of these would worked:
  In mod_webapp/warp connector I could use:
  WebAppDeploy minutes warpConnection /members/minutes/
 
  In mod_jk I could use:
  JkMount /members/minutes/*.jsp Worker
  JkMount /members/minutes/*.do Worker
 
  The question
  Is this possible in mod_jk2 and if so how do you do it?
 
  TIA

RE: Common/lib works shared/lib doesn't

[Andy Eastham]

Marc,

The only issue with having jars in common/lib, is that any static class
variables are shared across every webapp, as the class loader only loads
these classes once per server.  Classes under webapp/WEB-INF/lib are loaded
once per webapp and invisible to other webapps. 

For example, if you're using log4j, you can get every webapp logging to the
same file, even if each webapp initialises logging separately (the webapp
that initialises last wins).  This is because log4j uses static variables
to hold log configuration.  To prevent this, I keep a copy of log4j.jar in
webapp/WEB-INF/lib for every webapp.  I keep most other jars in common/lib
though

This is not to say that everything should be in webapp/WEB-INF/lib, just
that its worth knowing that there can be confusing consequences of sharing
jars across webapps.

 OK I'll leave it in common/lib. The problem with WEB-INF/lib is that is
 takes too much time to update all webapps. We have a rather cumbersome
 environment. Each app has to go through four environments (development,
 integration, certification, production) before it is available to the
 customer. Hopping from one environment to the next can take up to two
 days each because after Sarbanes-Oxley all we developers have access to
 is development and that's it. Now imagine I have 30 apps using this jar.
 If I need to make a change to the jar it becomes a nightmare to deploy.
 
 Thanks for the help tho =)

RE: AW: IP Adresses

[Andy Eastham]

Gunnar,

You are contacting the developers of Tomcat.  I'm not one myself, but I bet
some of the people who have put in vast amounts of their own time
voluntarily to develop Tomcat would be quite offended by your comment.

I also wouldn't be surprised if the reason that you can't run another web
server on port 80 is due to your own misconfiguration and not actually a bug
in Tomcat at all.  

But as Tomcat is open source, you could of course check the source yourself
to confirm this.  If you did indeed find a bug, you could even fix it.
That's how open source software works.

 Thanks, this time it helps. But Tomcat still blocking all my ip adresses.
 I
 cannot run other web server on the other IP with the port 80 :(
 
 Nevertheless I'll find a different solution.
 How can we contact the developer of tomcat? Maybe it is a bug and will be
 fixed in version 6 or 7 ;-)
 
 Many thanks!

Off Topic - Java Graphing Package

Hi,

Sorry this is a bit off topic, but can anyone recommend an open source or
freeware toolkit for building bar charts and graphs in java?

I am going to use it within Tomcat, but I could probably use something
that's aimed at applets if I had the source code.

Thanks to anyone who responds.

RE: SSL and sessions

[Andy Eastham]

Glen,

I found this a right pain, and currently I'm using SSL for the whole app.
But this is storing up performance problems as I'm sending fairly high rez
astronomical images over SSL and I know I'll have to fix it sometime.

The way I'm thinking of getting round it is to send back a one time key in a
cookie in the redirect page, that is the key to an application visible
hashtable where I'll put the original session as the value against this key.
When the redirect occurs, I'll read my key cookie to get the one time key to
retrieve the original session, then create a new session for the insecure
request, and copy everything I need from the secure session to the new
session.

I haven't tried this yet though and if anyone's got any better ideas, I'd be
pleased to hear them...

RE: [OT?] Apache Portable Runtime JK2

[Andy Eastham]

Matt,

I built it on Solaris 9.  I'd already built and installed apache 2, and all
required libraries were then installed.  Are you specifically trying to do
this without installing Apache2?

If not, here's my simple notes:
build mod_jk2:

download connector src:
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz

gunzip and untar the distribution, then
cd jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz/jk/native2
./configure --with-apxs2=/usr/local/apache2/bin/apxs
--with-java-home=/usr/java/j2sdk1.4.2
make

Built libraries are:
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz/jk/build/jk2/apache2/mod_jk2.
so
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz/jk/build/jk2/apache2/jkjni.so

Copy these libraries into /usr/local/apache2/modules
cp jakarta-tomcat-connectors-jk2-2.0.2-src/jk/build/jk2/apache2/mod_jk2.so
/usr/local/apache2/modules/
cp jakarta-tomcat-connectors-jk2-2.0.2-src/jk/build/jk2/apache2/jkjni.so
/usr/local/apache2/modules/ 

Obviously, the java and apache paths may be different, but hopefully this
might help?

1. Do I need APR to build JK2 on Solaris 9

2. If so where do I get APR and is the 0.9.4 version suitable?

RE: Tomcat and Log4J

[Andy Eastham]

Kent,

A gothcha to be aware of: if you put log4j.jar in common/lib, all webapps
will share the same log4j configuration.  This causes a race at server
startup - the last one to initialize log4j wins, ie gets it's own settings.
Everything else then logs into the same file.  This is a symptom of static
variables loaded by the same class loader, so all webapps share the same
instance of the static log4j variables.

I put log4j.jar in each of my webapps' WEB-INF/lib folder to avoid this,
then each webapp can configure log4j to it's own requirements.

Subject: RE: Tomcat and Log4J

 Howdy, Your problem is not log4j, it's commons-logging, which is nearly
always the culprit. The issue arises if log4j is in a classloader below
commons-logging, so
 commons-logging doesn't know log4j is there. You're configuring log4j OK,
and if you used a log4j Logger rather than a commons-logging Log, you'd see
expected 
 behavior. But you're using a commons-logging Log, which uses the
commons-logging configuration, which is tied to your server and outputs to
the console. Yoav
 Shapira Millennium ChemInformatics 

Shapira,

Thanks for the advice. I tried using Log4J directly by one of my classes
and, like you said, it worked. However, I wanted to stick with commons
logging since this is (supposedly) the most flexible logging solution.
Therefore, I tried sticking log4j.jar into ${TOMCAT_HOME}/common/lib and
log4j.xml into ${TOMCAT_HOME}/common/classes. This worked for Tomcat classes
but not my own (my log output was still going to stdout). This had me
stumped.

After further stuffing around, one of my work collegues mentioned he'd
gotten around this problem by including commons-logging.jar and
commons-logging-api.jar in his web app. I tried this and it worked. I then
removed commons-logging-api.jar from my web app and it still worked.

In a way this all kind of makes sense - my web app has its own commons
logging package which finds the log4j package and the configuration.
However, I am surprised that this was all necessary. I am also surprised
that it is (I think) undocumented.

Anyways, thanks for your help.

Kent

 Hi all,

 I have developed a small app with jawin (a java2COM bridge). I have used
 eclipse as a development tool and I referenced the jawin libraries and all
 works ok.

 the problem is when i deploy the app to Tomcat 4 and try to use a jsp to
 invoke my classes, I get an error that I can't solve.  I think is
 a problem
 of ubication of JAWIN libraries because when I try to get other class that
 does not use JAWIN, all works perfectly. I simplified the JSP in order to
 detect the error and I let it to invoke a simple constructor but goes on
 crashing!

 I tried to put jawin.dll and jawin.jar in the same directory that
 the class,
 in the app lib directory, in the common/lib directory of tomcat, in
 system32, in lib of the JRE, in bin of the JRE. it's useless, I don't
 know how to solve the error.


 The JSP is just as this.

 As you can see I only invoke the constructor but it crashes.

 I apologize for being so broad. Let me be more specific. It might

 We are running an intranet application running on apache and
 tomcat. It's all Java, using JSP and Servlets, and Struts. One
 function of the application is scanning in faxes. After being
 scanned, these documents are stored as TIFF files on the server
 temporarily. Right now, importing these images into the database
 is a manual process. There is a JSP page that has a Start Import
 button that invokes a servlet that imports these images into the
 database. My task is to make this an automated process so that
 any images that have been scanned in will get scanned in at
 night, say 3am. In other words, this code that is in this servlet
 that imports images needs to be called automatically every night at 3am.

 I hope that helps. Thanks.

I don't care if someone gets a session hijacked in my application, but I

Thanks much for the tip -- I have to disagree about this not being a
necessary change.  There are plenty of apps where people browse without
  a secure connection, but have to log in to perform some functions.
Users like to bookmark pages -- why should I force them to bookmark
only non-secure pages? Giving a developer control over how session
cookies function is better than forcing a hack where you have to always
redirect to a non-secure page to establish the session.  If you are
writing an application where the session data is so sensitive that you
have to protect against session hijacking, you should know about the
difference between secure and non-secure cookies.  I've got no problem
if the default behavior uses secure cookies when ever possible, but
change the Session uses cookie parameter to have a flag that allows
session cookies to always be non-secure.

Just my two-cent rant :)

 Subject: Problem with IIS tomcat 4.1 jk2 connector


 Hi

 First sorry for my english.

 We have a web server with tomcat 4.1.12 running with JK2 connector
 (isapi2_redirector.dll).
 The configuration works fine except for one link redirection
 calling a jsp.
 This problem appears only when using the jk2 connector because if
 we use the
 port 8080 with the tomcat standalone web server we have not this problem.


 The page is not reachable when we use the jk2 connector here is
 the log from
 from the connector.

 Why we have the path info 'null'


 Here is the host we are using in server.xml

 The only line in jk2.properties is:

 shm.file=C:\J2EE\jakarta-tomcat-4.1.12\logs\jk2.shm

 --
 --

 The jsp file is in the directory  f:\Site
 Internet\adesa\java\web\jsp so the
 root for our app is web.

 And as i say before, the problem does not appear when we use directly the
 tomcat web server org.apache.coyote.tomcat4.CoyoteConnector on a
 standalone
 port (here is 8080).

 Thank you.
 Regards.

RE: Obtaining JK2 binaries for Linux

[Andy Eastham]

Patrick,

I found this, but I did manage to compile them from source.

Unfortunately my notes don't seem to be that good, but here they are:
build mod_jk2:

download connector src:
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz

gunzip and untar
cd jakarta-tomcat-connectors-jk2-2.0.2-src/jk/native2
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-java-home=/usr/j
ava/j2sdk1.4.2
make

Built libraries are:
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz/jk/build/jk2/apache2/mod_jk2.
so
jakarta-tomcat-connectors-jk2-2.0.2-src.tar.gz/jk/build/jk2/apache2/jkjni.so

Copy these libraries into /usr/local/apache2/modules
cp jakarta-tomcat-connectors-jk2-2.0.2-src/jk/build/jk2/apache2/mod_jk2.so
/usr/local/apache2/modules/
cp jakarta-tomcat-connectors-jk2-2.0.2-src/jk/build/jk2/apache2/jkjni.so
/usr/local/apache2/modules/

Perhaps the options in configure above may be helpful?

 Hi,
 I try to set up JK2 for Apache/2.0.40 - Jakarta-Tomcat-4.1.29 on
 RedHat Linux 9.0.

 I cannot find the binary distribution for the connector, or
 cannot access it !
 The only binary distributions availables are for Solaris and Windows :(

 I am based in Switzerland and wonder if the smart mirrors
 redirection process
 head me to an incomplete mirror ? I tried directly accessing this
 URL found on
 some doc (outside Apache.org):

 http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/rele
ase/v1.2.2/bin/linux/i386/

But keep on being redirected to the official Apache binary download page.

I also tried building the connector from source
(jakarta-tomcat-connectors-jk2-2.0.2-src) but can't manage to have it done.

Any link, advice appreciated

Patrick

RE: What is a good dev-enviroment for servlet/tomcat?

[Andy Eastham]

Have you never run into a problem when multiple developers are working on
the same server, and someone crashes the server, overwrites someone else's
code, breaks something that someone else was relying on, or restarts the
server when someone was in the middle of testing a long running batch job?

I certainly have!

It's easy to ensure people in a small team have the same version.  Put up a
poster with Tomcat 4.1.18 or something written on it, or if they are
distributed around the world, email them weekly with what the approved
development environment is.  If they can't be trusted, replace them with
people who can ;-).

By all means have a single test server shared by everyone, but make sure
people only upload code that has at least been locally module tested.  That
way everyone won't tread on each others toes all the time, and if the test
server goes wrong, others can continue working in their local environments.

 Howdy,

 IMHO, instead of one instance per developer, I think you should have
 one
 development server with one instance of Tomcat shared by the 3
 developers.

 Why oh why do you think that??

  Hi,
 
  I'm having problems coordinating the startup scripts for Apache, Tomcat

  - mod_webapp requires Tomcat to be already running when httpd starts
 
  - the Tomcat application contains a connection pool that
 requires MySQL to
  be running when Tomcat starts (this is a crap architecture, but I havn't
  time to change it)
 
  I can execute the startup scripts manually in the sequence
  MySQL/Tomcat/Apache, and everything is fine.  But when they are executed
 at
  system boot it doesn't work.  The httpd log contains a web application
 not
  found message, and pages from the application are not available.
 
  I've renamed the startup scripts so that the sequence is correct, but it
  still doesn't work.  My guess is that most of the Tomcat
 startup forks, so
  that the httpd startup is invoked before it has completed.
 
  I can think of two very klugey workarounds:
 
  - call httpd restart at the end of the Tomcat startup - what
 will this do
 if
  the real httpd script is still executing?
 
  - make the httpd script sleep for a while before it does anything - but
  there's no way to guarantee it will sleep long enough
 
  Alternatively I could add code to the httpd script to see if Tomcat has
  completed its startup.  But I don't know for sure how I would tell, and
 I'd
  rather avoid this sort of hack if there's a proper way to do it.

Mod jk2 binaries

Hi,

Please could anyone tell me why there are no linux binaries for mod jk2
version 2.0.2 under
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk2/release/v2.0.

I've got to move something from Solaris to Linux and would be interested to
hear if there's a good reason for this before I embark on a wild goose
chase:-)

Was 2.0.2 a bug fix release that didn't effect linux sop people are using
2.0.1?

Or does 2.0.2 not work on Linux for some reason?  If so, does 2.0.1 work OK?

I've got 2.0.2 working fine on Solaris with the binary I downloaded from
under the above URL.

TIA,

RE: Using sendRedirect puts me into an infinite loop...

[Andy Eastham]

Mike,

The documentation is always your friend :-)

The docs say that relative urls are interpreted relative to the CURRENT
REQUEST URI, so the behaviour is as advertised:

*

sendRedirect
public void sendRedirect(java.lang.String location)
  throws java.io.IOExceptionSends a temporary redirect
response to the client using the specified redirect location URL. This
method can accept relative URLs; the servlet container must convert the
relative URL to an absolute URL before sending the response to the client.
If the location is relative without a leading '/' the container interprets
it as relative to the current request URI. If the location is relative with
a leading '/' the container interprets it as relative to the servlet
container root.
If the response has already been committed, this method throws an
IllegalStateException. After using this method, the response should be
considered to be committed and should not be written to.

Parameters:
location - the redirect location URL
Throws:
java.io.IOException - If an input or output exception occurs
IllegalStateException - If the response was committed



You need to hack it with starting the url off with /SHOW or get the
application name from the ServletContext, or read the start of the current
URI, or get it from a config file or somewhere.

All the best,

Andy

 Sorry for posting this here, but I either have a pretty big
 misunderstanding of something (most likely) or I've discovered a bug

 I have Apache Web Server set up thusly:

 ~~~
 VirtualHost xxx.xxx.xxx.xxx
   DocumentRoot /home/webhome/myapp/
   ServerName www.myApp.com
   ErrorLog /var/log/myapp/error_log
   CustomLog /var/log/myapp/access_log combined
 /VirtualHost

 ~~~

 Then in Tomcat server.xml:
 ~~~
 Context path=/SHOW docBase=/home/webhome/myapp/
 defaultSessionTimeout=60
 ~~~

 And finally in the web.xml for the application in question:
 ~~~
 servlet
 servlet-nameTrans/servlet-name
 servlet-classcom.acme.Translator/servlet-class
 load-on-startup0/load-on-startup
 /servlet
 .
 .
 .
 servlet-mapping
   servlet-nameTrans/servlet-name
   url-pattern//url-pattern
 /servlet-mapping
 ~~~
 So I think you can see with this setup, I have something like this:

 http://www.myapp.com/SHOW/1/Mike.Curwen
 http://www.myapp.com/SHOW/2/Other.Person
 http://www.myapp.com/SHOW/admin
 http://www.myapp.com/SHOW/reports

 The /admin and /reports requests will map to other 'known' servlets in
 web.xml  (and these work properly).

 Anything 'not' recognized will be picked up by my Translating servlet.
 (the default servlet) It expects certain formats.. meaning
 #/FirstName.LastName

 Never mind the robustness of that.. here is the code within the
 translator (the code of interest)

 ~~~
 public void handleRequest( HttpServletRequest request,
 HttpServletResponse response) throws Exception {

   HttpSession session = request.getSession(true);

   logger.debug(URI:  + request.getRequestURI());
   logger.debug(URL:  + request.getRequestURL());
   logger.debug(PATH:  + request.getPathInfo());


   String what_was_requested = request.getRequestURI();

   String newURL=(foo?);

   // large block of code snipped ... it translates the
   // 'encoded' request into a normalized querystring
   // for the 'foo' servlet.

   newURL = response.encodeRedirectURL(newURL);
   logger.debug(SHOW::  + request.getRequestURI() +  translates
 to:  + newURL);
   // redirect (our tracking filter won't pick up internally
 forwarded requests until servlet2.4)
   response.sendRedirect(newURL);
 ~~~



 So I'm translating from a #/FirstName.LastName format into a queryString
 that all other parts of my application can use.

 Here is what I get when I make a request for
 http://www.myapp.com/SHOW/1/Mike.Curwen
 ~~~
 DEBUG com.acme.Translator.handleRequest() - URI: /SHOW/1/Mike.Curwen

You can call Conection.isClosed(), but the documentation suggests that this

However, if it does return true, you know that you should reconnect before
attempting a call with the connection.

 Subject: A question about filters


 Hi

 After a lot of experimenting and hassle i've come to the
 conclusion that i have misundeerstood how filters work.

 I thought i could make a filter for the entire website, and all
 requests to that website would go through a specified filter.
 This is not possible, as far as i know?? You can only make
 filters connected to some webapp, and all requests to that webapp
 will go through the filter.

 What i mean is, if you have a site called :
   http://www.somesite.com/

 You can't set up a filter for all request with this url-pattern.

 You can set up a filter to :
   http://www.somesite.com/mywebapp/

 Or any other context that you specify after the website address.

 Anyone here know a way for me to set up a filter for all requests
 to a webiste ?

 Regards,
 Abid

RE: A question about filters

[Andy Eastham]

Abid,

The server web.xml is processed before the application web.xml, so it should
work.  You'll need to ensure the filter class is available to all webapps,
so /common/lib (for a jar) or /common/classes(for a .class) is where I'd
recommend.

You'll need to use a filter map such as *.

Why not give it a try and let us know what happens.

All the best,

Andy

The release notes of 4.1.18 refer to specific issues with 1.2.x - 1.3.x on

RE: getting a reply like this.

[Andy Eastham]

Jon,

I agree with what you say, except that the list probably thinks the message
send succeeded.  The message isn't bounced back to the list - the spam
warning goes back to the original sender contained in the From header.
The spam warning software is ignoring the Reply-To header.

Therefore the list may be oblivious to the problems, and the person behind
the firewall may think the list is broken because his posts and replies
don't make it through.

 I may be wrong but...

 This list knows nothing (as such) about [EMAIL PROTECTED]
 Here's what i believe is happening:

 1) You post to the list.
 2) List delivers said post to all subscribers. One subscriber is, say,
 [EMAIL PROTECTED]
 3) The Mail Daemon/Post Master at logicaonline.com rejects the post
 because the From address domain is hotmail.com and sends a rejection
 response to the From address (you). [EMAIL PROTECTED] is oblivious

 The list is probably noting that mails to [EMAIL PROTECTED] fail so
 that account may die automatically after a while.

 As John Turner noted earlier, it's a miscofiguration of the anti-spam
 filter at logicaonline. Blocking [EMAIL PROTECTED] would have no
 effect as no mails are directly sent to it.

 command line way.  I'm not even sure if ANT will do what I want.
 
 I want to have my .jsp files made into .java files (easy) then 
 compiled into .class files (hard) before starting my Tomcat.  
 That way I can see any syntax errors in my .jsp files.
 
 If I do this at the moment I get a load of errors where one JSP 
 which is included in another uses variables which are only 
 declared in the major one.
 
 Is there a way to compile the .java files the way Tomcat does 
 (which takes account of included .jsp's)?
 
 Does ANT create .class files?
 
 Thanks in advance.

I'm not sure what the problem is, but you can redirect the output in dos,

 I'm having issues with the web.xml file in my webapps/root/web-inf
 directory. What I want to do is be able to specify each individual
 servlet that can be run, by using servlet and servlet-mapping tags.
 Unfortunately, the best I have been able to do is use a generic servlet
 invoker to allow every servlet to be accessed. When I try to set things
 up so that only one servlet can be accessed, there are errors showing up
 in the dos box when I start Tomcat... which proceed to scroll of the
 screen faster than I can look at them. They do not show up in any of the
 logfiles in the logs directory. I was hoping someone could take a look
 at the web.xml file I'm using and tell me if my error is an obvious one,
 and how to fix it. I tried everything I could think of to make it work,
 and checked all the documentation I could find.

 I'm running Tomcat 4.1.24 on Windows 98.

 Thank you in advance,

Cookies and HTTPS through Apache

[Andy Eastham]

Hi,

I've got a site up and running which uses Tomcat via Apache2 and mod_jk2
(only - no direct access to Tomcat).

I manage logins using standard session management via cookies.

Some of the site is accessible by http, other bits are accessible via https.
This is managed by mod_rewrite in Apache.

I've noticed that if I make the login page an http page, the session cookie
is sent to the server in both http and https requests, so the person appears
logged in.

However, if the login page is accessed via https, the session cookie is only
sent to https requests, not http requests, so the user appears not logged in
on the non-secure pages.

I understand that this could usually be desirable behaviour - it keeps a
cookie given out over https secure.

However this is not the behaviour I want.  I want the login page to be https
to protect the password, but I want the session cookie to be passed in http
requests too.  Is there a way to make a cookie passed over https accessible
to http requests?  Is Tomcat doing this or Apache?

Is this clear?

Any suggestions or pointers to further reading would be very much
appreciated.

Best regards,

Andy

RE: Can't connect to X11 window server using '0:0' as the value ofthe display and now java.awt.HeadlessException

[Andy Eastham]

Hi,

I would say that Xvfb does _not_ connect to your display adapter - the v
stands for virtual, ie it's not a real frame buffer as in a video card -
it's a virtual one in your systems normal memory.

It's specifically for taking the place of a display adapter when your server
doesn't have one.

We always used to use this on sun E250s without a display adapter, but now
we use headless as it's more reliable.

 Yep: Done correctly, this is probably the more 'correct' solution, but,
 and I'm probably opening myself to a lot of flamebait, but I do suspect
 that using something like Xvfb might give some advantages that using
 headless won't. For example, and I'm just guessing, but I think that
 'headless' is purely a software solution, while Xvfb might be connected
 to your display adaptor, and therefor might be faster or less of a drain
 on your system resources.

 {
 But, like I said, I have no documentation to back up this statement,
 this is purely a guess and based on my personal findings: If anybody
 else knows differently, I would be very interested to know more, as I'm
 doing a lot more graphics orientated servlets, that usually run on
 headless boxes }

RE: Problems configuring Tomcat with Apache using mod_jk2

[Andy Eastham]

David,

This looks like jk config to me, not jk2.  If it helps, here are my working
config files for apache 2 and mod_jk2 on solaris.  (The workers.properties
file is called workers2.properties on my system, which is the default name).

My Httpd mapping looks like:
VirtualHost *
ServerName 192.168.0.102
ServerAlias www
ServerAlias localhost
ServerAdmin [EMAIL PROTECTED]
DocumentRoot /usr/local/apache2/htdocs

Location /control/
JkUriSet worker ajp13:localhost:8009
/Location
Location /wwwsadmin/
JkUriSet worker ajp13:localhost:8009
/Location
/VirtualHost

workers2.properties looks like:
[logger.apache2]
level=DEBUG

[shm]
file=/usr/local/apache2/logs/shm.file
size=1048576

# Example socket channel, override port and host.
[channel.socket:localhost:8009]

host=127.0.0.1

# define the worker
[ajp13:localhost:8009]

# Uri mapping

  /Service

I've found the key is to follow and check the path for each mapping in
httpd.conf through workers2.properties and then through server.xml.  Make
sure there's a match for each alias, and make sure you get all the IP
addresses right.  You don't get much help from any error messages if you get
this wrong.

Hope this helps - it took me a while to get it all working, but now it works
a treat and is very reliable.

 It would help if you post the entries you added in httpd.conf for Tomcat.
 Also include your server.xml file for more information.

 I have modified httpd.conf as follows:

 JKWorkersFile /opt/tomcat/conf/jk/workers.properties
 JKLogFile /opt/tomcat/logs/mod)jk.log
 Include /opt/tomcat/conf/auto/mod_jk.conf

 Server.xml is as follows (standard apart from the references

Rick,

That's a leftover from the file on the web I copied my config from - it's
commented out anyway.  I haven't a clue what it does.

All I know is that this set up works!

 The mystery to me is why there is a shm.file entry in
 jk2.properties...when the actual entry seems to need to be in
 workers2.properties.  The documentation is very sparse in this area.

  Kris, first, does your webapp started fine?
  If yes, we can have some situations for one class works in jsp
 files using
  tomcat:
  1- webapp
  |_WEB-INF
  |_classes
  |_yourclass - if your class doesn't have a package
  2- webapp
  |_WEB-INF
  |_classes
  |_pack
  |_subpk1
  |_subpk2
  |_yourclass -if your class is in
  package(s), in this case: pack.subpk1.subpk2.yourclass
 
  3- if your class is any jar, this jar file must be in /WEB-INF/lib(your
  class is shared only in especific webapp) or
 %CATALINA_HOME%/common/lib(your
  class is shared in webapp'S' and tomcat) or
  %CATALINA_HOME%/shared/lib(your class is shared in webapp'S').
 
  After this cases, if your class is in package(s), in you jsp
 file you have
  to use the import directive, for example:
  %@ page import=pack.subpk1.subpk2.* % or if import only  a especific
  class %@ page import=pack.subpk1.subpk2.yourclass %
 
  Well, i think that's.

RE: Strange error

[Andy Eastham]

Felipe,

Just one additional idea:

Are you executing another command on the same connection?  This destroys the
result set.

Eg, if you are trying to loop over the result set, and are using the same
connection to do an update or delete on this or another table, you will get
this sort of error.

 It
 uses

 same.  Just
   sub in apache wherever it says apache2.  I'm assuming you
 are
 using
   Solaris because you have paths with /opt in them.
   
   In my experience, you want to use:
   
   ./configure --with-apxs=/some/path/to/apache/bin/apxs
   make
   make install

Do you not need to name it too, ie
LoadModule jk2_module modules/mod_jk2-2.0.43.so

Thats what's in my working set up anyway.

RE: Pick a Platform - Linux, Windows, Unix, Solaris...

[Andy Eastham]

Adoni,

Version 4.1.18 seems to be the current one and seems to be stable for me.

As for platforms, the best one depends on the situation.

Personal use: go for your favourite platform.

Customer use:  Ask them what their favourite platform is.  If it's windows
protest mildly, tell them windows sucks, then install it on windows anyway.

As it's all written in Java, you basically run the same code, so it's down
to the Java VM.  Choose any platform that has a decent j2sdk1.4
implementation.

Actually Tomcat works fine on windows, but some of the connectors that
connect web servers to tomcat are less reliable on windows.  If you're just
running tomcat standalone, this doesn't matter

 http://; to request that same page?

 Would this be a proxy thing or is something I can set in Tomcat?  Is there

RE: Servlet Mapping Bug?

[Andy Eastham]

This is a bug, as I've now checked the Servlet Specification v2.3:

The key phrase is:
The path used for mapping to a servlet is the request URL from the request
object minus the context path.
ie for my /control/plots/x.jpg request, the context path is /control, so
only /plots/x.jpg should be used to map the servlet.

I guess this bug is probably in the Coyote Connector?

Andy

PS
Here's the full text of the relevant bit from the servlet spec:

SRV.11.1 Use of URL Paths
Upon receipt of a client request, the web container determines the web
application to which to forward it. The web application selected must have
the longest context path that matches the start of the request URL.

The matched part of the URL is the context path when mapping to servlets.
The web container next must locate the servlet to process the request using
the path mapping procedure described below:
The path used for mapping to a servlet is the request URL from the request
object minus the context path. The URL path mapping rules below are used in
order. The first successful match is used with no further matches attempted:

1. The container will try to find an exact match of the path of the request
to the path of the servlet. A successful match selects the servlet.

2. The container will recursively try to match the longest path-prefix: This
is done by stepping down the path tree a directory at a time, using the '/'
character as a path separator. The longest match determines the servlet
selected.

3. If the last segment in the URL path contains an extension (e.g. .jsp),
the servlet
container will try to match a servlet that handles requests for the
extension.
An extension is defined as the part of the last segment after the last '.'
character.

4. If neither of the previous three rules result in a servlet match, the
container will
attempt to serve content appropriate for the resource requested. If a
default
servlet is defined for the application, it will be used.
The container must use case-sensitive string comparisons for matching.

Note 1. Previous versions of this specification made use of these mapping
techniques a suggestion rather than a requirement, allowing servlet
containers to each have their different schemes for mapping client requests
to servlets.

 Hi,

 I've just upgraded from Tomcat 4.0.4b1 and apache 1.3 using warp to Tomcat
 4.1.18 and Apache 2.0.43 using mod_jk2.

 I use a feature of servlet mapping in web.xml, where I map any
 request under
 a particular directory to a single servlet.  My application is mapped from
 Apache under the url /control/ and I invoke myServlet with any
 request to
 the plots subdirectory.  In the old configuration, the relevant
 part of my
 web.xml looked like:

 servlet-mapping
 servlet-name
 myServlet
 /servlet-name
 url-pattern
 /plots/*
 /url-pattern
 /servlet-mapping

 However, in my new setup, I have had to change this to make it work:

 servlet-mapping
 servlet-name
 myServlet
 /servlet-name
 url-pattern
 /control/plots/*
 /url-pattern
 /servlet-mapping

 ie put the full URI in the url-pattern, not just the path relative to the
 Tomcat application root.

 This strikes me as less portable - if I change my url mapping from Apache,
 I'll have to edit my web.xml, which wouldn't have been necessary
 before.  Is
 this a bug, or has it really been changed to better comply with
 the Servlet
 spec?

 Have you configured the Tomcat application root?

 I don't mean in Apache, I mean in server.xml?

 For each context you configure, you can also specify the URL-prefix.

 default:
 !-- Tomcat Root Context --
 !--
   Context path= docBase=ROOT debug=0/
 --

 !-- Tomcat Examples Context --
 Context path=/examples docBase=examples debug=0 .


 etc.
 Maybe you could solve your problem by just configuring path=/control
 here...

RE: Pb with HEAD request

Cedric,

The servlet container automatically handles head requests by calling doGet
but then only returns the headers.  This can be very inefficient in cases
such as yours.

The O'Reilly Java Servlet Programming book suggests at the top of doGet()
do:
request.setContentType(correctContentTypeForThisRequest);
if (request.getMothod().equals(HEAD)) return;

I've never tried this though.

 Hi Kristján,

 Next to your reply , i've checked again, and discover that i MISSED it :-(

 So i've coded the doHead method , but it never seems to be called by my
 servlet. I can't manage to know if this is a client or a server issue.

 Anyone gets an idea. ?

 Anynyway, i think i will have to implement a cache , because some
 of my Get
 actions need many calculation, and doing this twice for the same request
 will decrease the application performance.

 Thanks for help, regards,

 From RFC 2616 about HTTP 1.1

 9.4 HEAD
 The HEAD method is identical to GET except that the server MUST
 NOT return a
 message-body in the response. The
 metainformation contained in the HTTP headers in response to a
 HEAD request
 SHOULD be identical to the
 information sent in response to a GET request. This method can be used for
 obtaining metainformation about the
 entity implied by the request without transferring the entity-body itself.
 This method is often used for testing
 hypertext links for validity, accessibility, and recent modification.
 The response to a HEAD request MAY be cacheable in the sense that the
 information contained in the response MAY
 be used to update a previously cached entity from that resource.
 If the new
 field values indicate that the cached entity
 differs from the current entity (as would be indicated by a change in
 Content-Length, Content-MD5, ETag
 or Last-Modified), then the cache MUST treat the cache entry as stale.

 You really should look into the servlet specification.
 I think if you override doHead for your servlet

 doHead(HttpServletRequest req, HttpServletResponse resp)

 Receives an HTTP HEAD request from the protected service method and
 handles the request.

 Default action for doHead is to simply call doGet

  Hi,

  The client is Internet Explorer 5.5. It loads the following simple HTML
 page :

  html
  body
  embed width=200 height=200
 src=http://localhost:8080/myContext/MyServlet
  
  /body
  /html

  The problem is that my servlet is invoked twice.

  My supposition is that IE is sending a HEAD (or GET) request to know
  the content type of the URL and then run the Adobe SVG plugin. When
  started the plugin connects also the servlet to get SVG content.
  HTTP spec says that HEAD request must return the same headers as GET
  request. What is sure is that my code is executed twice, not only
  the part that concerns response headers. But how can I do to know
  with the servlet if the request is a GET or a HEAD. I test the
  HttpRequest.getMethod() but it always return GET.

  Does someone know how to configure tomcat or anything else to
  avoid the two executions ?

  Thanks.

 Zack,

 Here's the mod_webapp.so binary that comes with Solaris 9, which I know is
 binary compatible with 8, therefore maybe 7 too?

 Give it a try anyway.

  Can anyone point me in the right direction, for

  Should I try mod_webapp, mod_jk, or mod_jk2?   I need
  a binary file, for whatever connector I choose.
  Please don't respond with RTFM.  There are no binaries
  avaiable in:
  http://jakarta.apache.org/builds/jakarta-tomcat-connectors/jk/rele
 ase/v1.2.0/bin/

 Also, there isn't even a Solaris 7 directory (only 6
 and 8).   Does that matter?

 I would prefer to use mod_webapp, due to the
 simplicity of the installation process.   I installed
 that on Win2000 a while ago, but there are no Solaris
 binaries available anywhere.

 Thanks.

RE: Session start

[Andy Eastham]

In my experience, IE 6 creates a new session cookie for each browser
window...

 Subject: RE: Session start


 Hi Mauro

 At least this one I can answer for you.

 You will deffinitely not be able to start a new session for each browser
 window opened if you are using session cookies.

 The Session cookie specification is slightly different to that of normal
 cookies. It shares the same rule that the browser will send the
 cookie only
 to the domain from which it originated. But the session cookie lasts the
 lifetime of the browser whereas the normal cookie will be saved. So if a
 browser is closed (not just a window of the same browser process)
 the cookie
 will die with it. All the browser windows share the same cookies and if a
 session cookie is available for a the domain being accessed the
 cookie will
 be sent along.

 I.o.w if your servlet/jsp makes a call to request.getSession(true); the
 session ID identified in the request will return the session object stored
 at the server identified by the session ID in the request
 (cookie) if there
 is no session id or the session has expired on the server a new
 session will
 be created and a request will be made to the browser to kindly return a
 session cookie with the supplied id. If request.getSession(false); is
 called, the same process as above occurs but a new session will not be
 created.

 Thus to understand who the session id belongs to the answer is something
 like: The session id as a cookie is kept for the lifetime of a browser
 process on the client and identified on the server. Different vendor
 browsers will all have their own session cookies and thus session ids.

 To solve your problem it is correct what Ralph said.
 A session cookie cannot be used because the cookie is shared by
 all browser
 windows of the same browser process. The sollution is url
 rewriting in which
 the session id is not sent by a cookie but is sent as a request parameter
 and thus if the client opens a new browser window and types in your URL it
 will not contain the session id request parameter and thus a new
 session can
 be created on the server. This might not be the case if the
 client asks for
 a link on your application to open in a new window because the parameter
 might be in the link.

 I hope this makes it slightly clearer.

 Nick.

 OK, but I still have some servlets that have to communicate using
 HttpSession setting and getting objects between them.  So if on each call
 to different servlets I obtain a new session, then I loose the objects
 contained in the session.

 So reading your answer I think that the problem is to who belongs the
 session id.  Does it belongs to the machine that is browsing? I mean: the
 IP address? I don't think so because in multiple text sessions of the same
 linux machine, browsing from each the same servlet, I obtain different
 sessions.  Does it belongs to the user?  which user?  windows user?  linux
 user? other OS users?  No, the same user on different linux sessions, gets
 different HttpSession.  So I have to think that depends on the
 OS.  E.g. on linux it depends on the linux session.  I'd like to bypass
 this behavior opening a session each time a user opens a browser.  I
 think I have to rescue a browser window id or something like that from
 the HttpServletRequest.

 Any ideas?

  To do what you want you have to disable cookies

 Hi all

 I been having a very strange problem with the ajp13 connector..

 OK the senario is this.. I have apache configured with ajp13 and
 mod_jk.so .. Everything is working ok.. and I have Jboss + Tomcat
 that apache is talking to.. Everything..is working there also..

 I am doing ab ( Apache Bench ) tests to this setup, I start the
 Jboss bundle and do a test... I get some errors on the test
 telling me that about 60% of the requests fails !

 Ok Then. I open tomcat4-service.xml and JUST write it to deploy
 it again ( I dont change anything ) ..  and do another AB test..
 and guess what.. NO errors.. ??!?!?!

 I have done this about 50 times to verify that I am not
 mistaken.. So do anyone have a CLUE what could be going on with
 the connection..

 These are my ajp13 settings on Jboss..

RE: mod_webapp and multithreading for concurrent requests

[Andy Eastham]

Eliot,

Webapp does appear single threaded on win32.  I'd go so far as to say it's
unusable in a production environment on win32.  I develop using it on my win
2k laptop and deploy on linux or Solaris.  Webapp is forever hanging when I
try to execute concurrent requests from the same browser on windows.  It
seams OK on Unix though.

I think you should consider using mod_jk or mod_jk2 on windows as they are
currently actively developed.  However, I don't know for sure as I wouldn't
even _think_ about deploying a production system on windows anyway...

Sorry to be the bearer of bad news...

 Subject: mod_webapp and multithreading for concurrent requests


 Hi all,

 I'm running Apache 1.3.27, Tomcat 4.1.12 (both as services on Win32)
 with mod_webapp, and I need someone to explain to me how mod_webapp
 passes requests to Tomcat. The docs are a bit thin.

 I have a couple of test servlets: waiter and notifier. When I hit the
 waiter it blocks waiting for the notifier to notify it. When I hit the
 notifier it notifies the waiter and writes some output to the browser.
 The waiter then writes some output too so I can see that both
 have finished.

 I actually have Tomcat set up with both the WARP connector listening to
 requests that come via Apache, and the Coyote connector listening to
 requests diurectly on port 8080.

 When I hit the servlets on port 8080 everything works as expected. But
 when I hit them on port 80, via mod_webapp, there's a problem: the
 notifer never gets to execute. It seems mod_webapp is behaving as if
 it's a single thread (I have read stuff that suggests it is not, and I
 would hope it's not for obvious performance reasons). What I'm seeing is
 that the request for the writer is handled just fine up to the point
 where it blocks, but when I hit the notifier the request is never
 processed because the thread is still handling the waiter request.

 Can anyone shed any light on this?

 Thanks in advance,

 Eliot Stock

RE: Warp connections

Title: Re: Warp connections



Siggi,

What 
this means is that if you map, for example, /myapp to Tomcat, Tomcat will serve 
all content under /myapp. You cannot get Apache to serve 
/myapp/my.jpg.

Apache 
will still serve things that aren't under /myapp, so /index.html, /images/my.jpg 
etc _will_ be served by Apache.

Does 
this clarify the situation?

Someone with more experience may have a better answer but it 
is myunderstanding that mod_webapp does not permit you to distinguish 
betweenstatic and dynamic content. When you use mod_webapp, Tomcat 
services allrequests; i.e., you can't do what you want to do--serve html 
with Apacheand jsp/servlets with Tomcat--using mod_webapp -- you would 
have tocontinue using mod_jk if that's what you want to 
do.--Jim==Jim

  If I deploy examples webapp and access it through Tomcat's standalone

  When I access it through Apache, it works well until I find some kind of
  redirection (ie /examples/ - /examples/index.html), then I get a page

  Apache Tomcat/4.0.3 -HTTP Status 302 - Moved Temporarily

  If I try to connect using telnet, the response with port 8080 is:
  HTTP/1.1 302 Moved Temporarily
  while through Apache is:
  HTTP/1.1 Moved Temporarily
  Nevertheless, in access.log of Apache the status code for my request is
  correctly set to 302.
  Same behaviour if I do a sendRedirect from within a servlet or jsp,
  redirecting to another servlet (no static content at all).
 
  Can anybody help me?

RE: Best practice advice sought: Classes shared by 1 webapp

[Andy Eastham]

Jim,

If you want the webapps to share the same static values in the same class,
put them in common/classes. (this allows a webapps to affect the data in
another webapp).

If you want the webapps to be totally independent, put a separate copy in
each webapp's individual classes directory.

Or you may want to share some classes and not share others. Put them in the
appropriate place according to the above.

Note: This is because each webapp has it's own class loader, so behaviour is
different to normal java programs where static values are shared across
the whole virtual machine.

Hope this helps a bit,

 Or put the class in Tomcat's common/classes/ directory structure?  These

 Also, these web applications are for our own internal use only, not ones
 that we will bundle up and distribute, though we will need to

 Subject: Apache 2.0.40 + mod_jk + Tomcat 4.1.9 + Load Balancing


 Hi All,

 Last January I wrote up a document on how to set up Apache 1.3 with
 mod_jk and tomcat 4.0.2 on Linux with load balancing.
 (see www.ubeans.com/tomcat).

 Last week I suceeded in setting up Apache 2.0.40 with mod_jk and
 Tomcat 4.1.9 beta on Linux.

 Is there any interest in this group for me to write up a howto for this
 new setup?

 Pascal

RE: I have connector problem while using tomcat 4+apach 1.3

[Andy Eastham]

Taehun,

I had exactly this problem last week.  Tomcat is fine with mod_webapp on
windows 2000 and linux,but _binary_ file uploads fail on Solaris.  It seems
to be a bug in the Solaris version of mod_webapp (I used the one shipped
with Solaris 9).

I'm afraid I didn't fix the problem - I just deployed this particular
application on Linux rather than Solaris.

I'd be interested if you find a solution though.

All the best,

Andy

 Subject: I have connector problem while using tomcat 4+apach 1.3
 Importance: High


 Hi, All!

 I'm running Tomcat 4.0 and Apache 1.3 on Solaris8.
 I succeed in install and configuration except one thing.
 The problem is FILE UPLOAD. My file upload servlet working well
 when I run Tomcat as standalone only. I can upload any kind of file.
 But If I start apache server and try to upload file via apache, I can't
 upload any file except plain text file.(eg. .txt, .html)
 other files are just uploaded the part of them. what I mean is that
 if I try to upload 500 bytes sized file, only about 50 bytes are uploaded.
 (the uploaded size is not fixed)

 I think warp connector may cause this problem but not sure and I couldn't
 solve this problem. Anybody has some idea, let me know please.

 best regards

 Taehun

RE: Run Tomcat as tomcat user

[Andy Eastham]

Urtzi,

You need to grant access to the tomcat user.  See the section in the GRANT
command in the mysql manual (available online at the www.mysql.com site).
By default, root can connect without a password, but other users need to be
granted access.

You'll need to execute something like:
GRANT ALL PRIVILEGES on *.* to nobody@yourhostname identified by
‘nobodyspassword’;

The password is not the unix password - its mysql specific and set by this
command.

I recommend you read up to make sure you're only grant what you need - after
all there's no point running as nobody if it can do everything root can...

Test it by doing
su - nobody
then check that you can connect with the password you've set.

 something like that in the directory?
 I know how to handle that with Apache but the htdocs directory has
 nothing to do with Tomcats webapps. Therefore, there has to be another

 I'm having some difficulty understanding the solution u guys
 provided me... maybe I explained my problem badly, so u aren't
 fully understanding it...

 but I have a question that is quite simple:
 Is it possible for a class (or Servlet) located in
 $tomcat_home\common\classes - that will be accessed from all
 webapps - to know from which context a JSP/Servlet called it?

 for example... I have a class A in common\classes and it has a
 method doSomething()... say I have a JSP
 $tomcat_home\webapps\test\1.jsp that looks something like:

 %@page import=A%
 %
 String x = A.doSomething();
 %

 so... would it be possible for A to know that when doSomething()
 was called, the context was test?

 A JSP is a servlet, so you shouldn't need to create another class derived
 from servlet to do the job.

 If your call is directly to a servlet, that servlet can use the code for
 parameter lookup itself as is.

 the Servlet can't find the context in which the JSP that called it is...

 TesteDispatcher is the Servlet, and TesteCallDispatcher is just a dummy

 * I then placed both classes in $tomcat_home\common\classes

 * created a context called \teste1
 Context path=/teste1 docBase=teste1 debug=0 reloadable=true

 %@page import=dispatch.TesteCallDispatcher%

 TesteCallDispatcher tcd = new TesteCallDispatcher();
 out.println(A URL para esse contexto é \+tcd.myContextURL()+\.);

 when I execute it, nothing happens... there is a call in TesteDispatcher

 Or even simpler why not store it as a parameter in the
 server.xml. You will
 need to add the parameter to each of your contexts in the server.xml as
 follows:-

 Context path=/examples docBase=examples 
 ..
 Parameter name=db.url value=jdbc:postgres://localhost/mydb
 override=false/
 /Context

 And then in your servlet code you use the following to retrieve it (from
 your servlet):-

 getServletContext().getInitParameter(db.url)

RE: Feasibility question

[Andy Eastham]

Iain,

I don't think session sharing is easy, but you can implement login using
cookies, which will be shared if they come from the same server (or domain
if they are domain cookies).

Another alternative is to pass a session id in the URL, and store session
information yourself in a server persistent object.  If you write a
singleton class and put it in a jar under Tomcat/common/lib, instances will
be shared between webapps (on Tomcat Version 4.0.3 anyway).

Of course, you can also write session information to a database.  When a
user logs in, generate a unique key, write this into a Logins table as the
primary key, plus other information like time of login, time of last access
etc. When you get a request, check the cookie id against this table to see
if the user is logged in and their session hasn't expired.  If so, update
the time of last access.

Of course, non of these are as easy or efficient as the off the shelf
sessions, but all are valid ways of achieving what you want.

All the best,

Andy

 Subject: Feasibility question


 Hi List,

 relatively new to Tomcat, so excuse the possible repetition / naivety of
 this posting. We currently have an expanding web application
 running. We are
 thinking of dividing it up into more user-friendly chunks (different
 applications), allowing us to control each application more
 easily (stop one
 without affecting others etc.). My question is, is it possible to pass
 session info between many different applications?

 For example, these are our surveys, which we want as different apps.
 1. Login and generic registration
 2. Spring birdwatch
 3. Garden birdwatch
 4. Other survey and so on.
 They will all be attached to one Oracle installation.

 Currently, 1 and 2 are combined, so no problem with session info.
 But is it
 possible to transfer the user details between these apps, so that someone
 who is in Spring, can move over to Garden without having to login again?

 or not.

RE: Feasibility question

[Andy Eastham]

Iain,

By off the shelf sessions, I mean the ones you are already using  when you
don't need to share them across webapps (ie created by the servlet container
by request.getSession(true)).

Sorry for the confusion.

 Andy,

  Of course, non of these are as easy or efficient as the off the shelf
  sessions, but all are valid ways of achieving what you want.

 if you can spare a minute, can you be more specific about these 'off the
 shelf' sessions?

 Thanks

RE: tomcat won't load oracle driver

[Andy Eastham]

I think the problem ,ay be that 1.4 uses jdbc v3.  The oracle drivers
probably have require jdbc v2 hardcoded in them.  I remember this being
the case for a particular set of drivers, though I'm not absolutely sure it
was Oracle.  Are there any new ones from Oracle?

RE: Apache+Tomcat

[Andy Eastham]

Icaro,

Is it complaining that you've got IfModule statements where you should
have a virtual host section.  Perhaps you can't use IfModule here.?
I don't have any IfModule statements around the WebApp lines in my setup.

Just try removing lines 992 and 995 and I think it will stop complaining.
Of course, it wouldn't work anyway if it can't load mod_webapp.

The Free for a reason comment is a too harsh.  Most Apache Foundation

 Well said, and I agree 100%.  I spent 8 business days trying to
 get Apache 2
 with Tomcat 4 working, both with mod_webapp and mod_jk, before
 giving up and
 going back to Apache 1.3.  Granted, I am not experienced with
 tomcat, which
 may account for some of the delay, but your comments are right on
 the money.

 All due respect to the developers, but the idea that Apache 2,
 Tomcat 4, and
 the connectors are all separate projects, with little or no
 coordination (as
 far as I can tell) is really disappointing.  To me, that seems like a big
 mistake.

RE: Native library cannot be loaded twice

Andreasm,

By the way, the java library path is completely different from the system
library path.  I've got mine in
/usr/j2sdk1.4.0/jre/lib/i386/client/myLibrary.so , which is a default
library location for java (obviously you may have to amend the start of the
path slightly for your installation).  I guess the same path offset will
apply under windows - I disn't see which platform you're using.

 All,

 I've been trying to get the following configuration to work.

   Windows NT
   Apache 2.0.39
   Tomcat 4.1.3 beta

 Separately, I can see the Apache default 'Welcome' by going to
 http://localhost; in a similar vein I can see Tomcat's default
 'Welcome' by
 going to http://localhost:8080/index.jsp.  What I can't make work
 is seeing
 Tomcat's 'Welcome' page by going to http://localhost/index.jsp
 (or any other
 path for that matter!).  I've rebuilt the connectors for Tomcat, download
 the mod_jk.dll from www.acg-gmbh.de/mod_jk, and set up my
 workers.properties
 and mod_jk.conf files (similar to what I used under Tomcat 3.3.1
 - maybe the
 problem?)  Does anyone have any ideas why I can't see my JSP pages without
 needing to specify the port?

 Thanks in advance!

 I'm not sure if this is typical or part of my problem.

 LoadModule webapp_module libexec/mod_webapp.so
 
 WebAppConnection conn  warp  localhost:8008
 WebAppDeploy myapp  conn  /myapp
 WebAppInfo /webapp-info
 
 myapp is named exactly as it exists in my /home/tomcat/webapps 
 directory.  When I access either http://host/myapp or
 http://host/webapp-info, I receive a 404 error in the Apache 
 access log and the error log is looking for 
 /usr/local/apache/htdocs/myapp.
 
 Can anyone point out what I may be doing wrong?
 
 Thanks in advance!

Yoav,

Signal 10 is a bus error on the solaris box. Basically this a is an internal
data communication error in the machine.

I think these errors can be software related, as well as hardware related.
First off, make sure you've got all the latest patches for your operating
system.  After that, check there are no loose cables in the disk system
inside the box.  Have you added any new disks recently?  After that, I'm
afraid you'll need help from a Sun expert.

 Any insight or information would be appreciated, as well as tips on

If your server is running on Windows, I believe this is a common connector

 Subject: Tomcat 4 problem?--Graphics randomly fail to load


 Hi everyone,

 I've encountered a bizarre problem with Tomcat 4 stand-alone,
 regarding the loading of graphics. Some of the graphics for my
 site wil load, while others will not, as if they weren't located
 on the server. After thorough experimentation with what's NOT
 happening, I'm forced to believe that it's the server that's
 causing the problem. I searched the tomcat list archives and
 couldn't find a similar report, so I'm hoping that someone out
 there has experienced this anomaly. Your feedback is much appreciated.

 Just to clarify what is NOT happening:

 1. The graphics (.gif format) are properly located on the server,
 in valid file formats, with correct permissions.

 2. When forcing the server to load a graphic, either by selecting
 Show Picture from the browser's context menu or accessing a
 single graphic through a URL request, the graphic loads correctly
 every time.

 3. This symptom may occur even on tiled images, such as body
 background graphics. Some of the tiles draw, while others do not.
 This symptom is present on IE5 and Netscape 6.2, tested on Win2k
 and MacOS X.

 4. The problem occurs randomly; it does not seem to be
 predictable/reproduceable. A graphic will load correctly in one
 instance and fail to load in another.

RE: REPOST: Problems serving PDF to Netscape browsers

[Andy Eastham]

Jeff,

As a last resort, you could write the pdf to a temporary directory
accessible via apache, then send the browser a redirect to that file.  That
way, the actual PDF will be served by apache, not Tomcat.  You'll obviously
have to tidy up the generated PDFs periodically, although the temp file
methods in java.io.File should help. Also, java.util.Timer is useful for
writing jobs which do clean up tasks.

This is of course undesirable, but sometimes you just have to do what it
takes to make something work... :-(

Good luck,

Andy

 Subject: REPOST: Problems serving PDF to Netscape browsers


 I've made no progress on this, so let's try again. My dynamic
 PDF is working perfectly with MSIE 4, 5, and 6, but I'm still
 having problems with Netscape (ver 4 and 6) and the Acrobat
 (ver 4 and 5) plugin. I've tried this on various client machines.

 With both NS4 and NS6, I just get a blank screen when I request
 my dynamic PDF. They don't even show the Acrobat toolbar. The
 similarities end there.

 In NS4, the first request does not launch the AcroRd32.exe
 process. In fact, it fails to read the entire output of the
 servlet and Tomcat (4.0.3) spits out a Broken Pipe exception
 to the logs. If I hit Reload, however, I get my PDF and the
 plugin works. According to the Apache logs, the first unsucessful
 request returns 6144 of 21212 bytes before the broken pipe. On
 the Reload, the Apache log shows TWO requests returning the
 full 21212 bytes and Netscape displays it in the plugin.

 In NS6, the first request DOES launch the plugin executable, but
 that's as far as it gets. Reload doesn't help. My Apache server
 reports the correct number of bytes for the full PDF request, so the
 data seems to be getting to the browser. No exceptions are thrown
 by Tomcat.

 In both NS4 and NS6, it works if I configure Acrobat to be launched
 as an external application instead of a plugin. But it is not a
 viable option to impose that configuration on our customers.

 I use a servlet mapping that sends requests for xxx.pdf to my
 servlet, thus the browser sees a .pdf filename. I also use
 setContentType(application/pdf). There are known problems
 with MSIE and unknown ContentLength with PDF so I create the
 PDF in a ByteArrayOutputStream so I can know and set the
 ContentLength before writing to response.getOutputStream().

 To take the dynamic nature of the PDF out of the equation, I was
 able to reproduce these problems --sometimes-- when serving static
 PDF files via Tomcat.

RE: Problems serving PDF to Netscape browsers

[Andy Eastham]

Jeff,

I just tried this through my apache(1.3.20)-tomcat(4.0.4b1) connection using
warp, serving the document from a webapp directory, through apache.
Ironically, the pdf worked correctly in ns 4.72 and 6.2, but displayed as
binary in the browser in ie 6 (even though right clicking and viewing
properties said it was an adobe acrobat document.  When I put the same
file in the apache root, it displayed correctly in all browsers.

There's obviously something screwy going on, because I've checked the mime
type is correctly configured in both.

For reference, these are the headers that came back using a telnet
connection on port 80:

 The content type header is correctly set to application/pdf.
 I even tested with a UNIX command line utility called webgrab
 which dumps the entire server response (including headers) to stdout.
 I can't find anything wrong with the server output. And yes, I tried
 it on another box to make sure it wasn't my system's fault.

 It's got to be something that the Netscape plugin doesn't like. I just
 uninstalled Acrobat and did my dynamic PDF page with all three browsers.
 Without Acrobat, they all just prompted me to save it as a file. All three
 files that I generated with each browser are identical!!! And once Acrobat
 was re-installed, they all opened just fine in the stand-alone Acrobat.

  Jeff,
 
  Do you know that the correct mime type is being sent back to
 the browser?
  If there is no known mime type, I believe that IE makes guesses
 about what
  program to launch a file with based on its extension, but NS 4
 doesn't seem
  to do this.
 
  If you haven't solved it yet, check the mime type being served,
 and check
  the associated programs for this mime type in Netscape.
 
  Otherwise, check the log file to see if the requests from IE and NS are
  different.  Is one http 1.0 and http 1.1?
 
  Sorry if I'm not offering any solutions, but hopefully these are some
  additional routes for investigation.

RE: Servlet init() callin twice on startup. PLease help.

[Andy Eastham]

Ivan,

I had this problem.  I found it was caused when you use Tomcat Standalone
and Tomcat Apache (at least when using mod_webapp / warp).  I don't need
Tomcat Standalone, so I removed it from server.xml.  It seemed that a
separate class instance was being loaded for each (I tested 4.0.1 and
4.0.4b1).  If you need both access methods, you can at least share the same
instance by putting your classes in Tomcat/common/lib in a jar, rather than
webapps/appname/classes, although the init() method will still get called
twice.  You just have to write the init method so that it already knows it's
been called.

By the way, if you remove Tomcat standalone, to get Tomcat to call the init
method, you have to start Tomcat then restart Apache.

Personally, I'm not sure this behaviour is As Designed, but this fixed it
for me.  I, like most others it seems, find the whole area involving
connectors somewhat difficult to understand.  I don't see why different
connectors should involve different sets of class instances.

Hope this helps,

Andy

 And when I see log - i can see that servlet was started twice.
 I need to start it one.

RE: How do I pass commands like -verify to the VM in NT Service mode?

[Andy Eastham]

Alexander,

I don't run it as a service, but services are controlled under the registry
key
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services]

You should be able to find the relevant bit underneath here, where the
command line for starting up Tomcat will be evident.  It will either be a
direct command, or a bat file.
