Datasource and Realm (at least in the configuration/implementation), are
Tomcat-specific features.

As a rule of thumb, anything that requires that you edit "server.xml" is a
Tomcat-specific feature.  If your web-app works without touching the default
"server.xml", then there is a good chance that it will work in any 2.3
container.

Re: disable directory listing in tomcat 4.1.12

[Bill Barker]

Yeah, well, there are a lot of thing that I miss from 3.3 that aren't in
4.1.x :)

To answer your question, you need to edit the $CATALINA_HOME/conf/web.xml
file, and change the listings param-value for the
"default" servlet from "true" to "false".

Re: SUCCESSFUL Tomcat Install!

There are many Jakarta committers that have successfully made a "go" of it
by having their own Server-Side consulting firms (but I'm not one of them
:).

As every one here should know, Tomcat is not a J2EE container.  For an OS
J2EE container that uses Tomcat for its Servlet/JSP, see
http://www.jboss.org/.

Re: SUCCESSFUL Tomcat Install!

[Jacob Hookom]

The best newbie-book i have read for starting with JSP's, Servlets, and
Taglibs is:

"Java Developer's Guide to Servlets and JSP" by Bill Brogden under Sybex
publishing

It's the book that everyone still borrows from me to read as a starting
point.  Now, I mainly use Jason Hunter's O'Reilly book titled "Java Servlet
Programming" as a quick reference.

Request Does Not Include Session Id - Why?

[bido]

For some odd reason the JSP session id is not being written to the  
request object and therefore I get null pointer errors when I try to  
reference session objects within a servlet.  Please note that, I do not  
want to send the client session in the URL.  I tried several different  
browsers  IE, OmniWeb, Chimera, Mozilla. The problem seems to be  
browser independent. Is this a Tomcat 4.1 security issue? I'm very  
confused since I thought that JSPs provide behind the scenes session  
management via cookies.  Too make matters even stranger, every once in  
a while the JSP will work correctly... I still haven't figured out the  
reason... I guess every once in a while the client and server session  
ids match by coincidence -ouch!

Here's a print out of my log messages (note that the request is passed  
correctly, the dates below come from the client)

 
***
JSP Session id: 3F6FC46A183303B69EC4E8097528159E
Request Session id: null
Servlet Active Session id: F8568A66D6EF4BE71AC8AD37FF0921C7
Servlet Active Session new?: true
Is Requested Session Valid? false
Is Requested Session from Cookie? false
Is Requested Session from URL? false
FromDate : Oct/10/2002
ToDate : Oct/19/2002

Any help will be greatly appreciated.

Thanks!

Re: Starting tomcat as user apache instead of root

[Nikola Milutinovic]

Randy Paries wrote:

Thanks
The problem is that they have to both read and write files

The weird thing is if I do a 
su - apache -c "$TOMCAT_HOME/bin/startup.sh"

It does not start

But if I do a 

su - tomcat -c "$TOMCAT_HOME/bin/startup.sh"

Is does. The one diff is that in the etc/passwd file
apache:x:48:48:Apache:/var/www:/bin/false
tomcat:x:505:48::/home/tomcat:/bin/bash 

"su - " will execute login scripts and activate user's shell. As Apache 
has "/bin/false" for a shell, it will exit immediately. You should try "su 
 -c" instead. On our Tru64 UNIX "su" will complain if you try both "-" and 
"-c".

So I assume it can not start because of the shell.

So how does apache start.


su apache -c "/usr/local/apache2/bin/apachectl start"


Should I just give apache a shell?


No.

Nix.

RE: how many tomcat in a machine?

If you put Log4j in one of the parent classloaders that Tomcat makes 
available to webapps ( shared/lib, common/lib ) then That will be one 
instance of log4j serving many webapps.  Actually, all webapps would use 
the same default logger repository or, hierarchy unless you do specifically 
create a new logger repository for each webapp using a custom logger 
repository selector.  See the following doc on this:

http://qos.ch/containers/sc.html

I implemented a logger repository selector similar to the one described in 
that article called Log4jCRS.  You can find it here:

http://barracuda.enhydra.org/software/cvs/cvsweb.cgi/Projects/EnhydraOrg/toolsTech/Barracuda/src/org/enhydra/barracuda/log4j/

It is used in both a Log4jInit servlet and a servlet context listener 
called Log4jApplicationWatch to initialize and shutdown loggers and 
appenders, respectively.

http://barracuda.enhydra.org/software/cvs/cvsweb.cgi/Projects/EnhydraOrg/toolsTech/Barracuda/src/org/enhydra/barracuda/webapp/log4j/


Log4jCRS needs to be in a classloader visible to log4j.jar.  This means if 
Log4j.jar is in common/lib (where commons logging likes it to be) you can 
put Log4jCRS in shared/lib or common/lib.  You can't put it in WEB-INF/lib 
of your app unless you also place a copy of log4j.jar there as well because 
Log4jCRS needs to talk to classes in Log4j.jar and vice-versa.

Log4jInit and Log4jApplicationWatch *must* be in WEB-INF/lib.  This is 
because the custom logger repositories are keyed on each unique webapp 
classloader and so must be loaded in the webapp classloader of each 
individual application in order to support that condition.

You can store your log4j config file (properties or xml) in WEB-INF and 
provide something like the following to configure Log4jApplicationWatch and 
Log4jInit :





org.enhydra.barracuda.webapp.log4j.Log4jApplicationWatch








log4j-init
org.enhydra.barracuda.webapp.log4j.Log4jInit


log4j-config
WEB-INF/log4j.xml



log4j-cron
5000



1


And for logging to file, a system variable is automatically created by 
Log4jInit.  The name is different for each webapp and predictable because 
it is based on the context name of the webapp.  For instance,  if I have a 
context with a path of "/Barracuda", then in my log4j.xml I use the 
variable ${Barracuda.log.home} to specify my filepath for a file appender 
such as:









As you can see above in the configuratin for Log4jInit, there is a param 
you can set called "log4-log-home" where you can set any custom file path 
for the directory where the log file should exist.  As is expained above, 
this defaults to WEB-INF/logs of your current webapp.  Note that this 
assumes that the app is served out of a directory on the filesystem.  If 
you serve your context directly from a .war file and you still want to use 
a file appender, you will want to set the "log4j-log-home" parameter to a 
place that you know exists as a directory on your filesystem.

That's about all the resources you need to use one instance of log4j.jar in 
common/lib and share it across all webapps without having each webapp's 
configuration interfere with any other webapp.  Without Log4jCRS, all 
webapps in this case would run over each other because they would all use 
the same default logger repository.  If you want to simplify things and not 
use Log4jCRS, then just make sure to put log4j.jar in every webapp's 
WEB-INF/lib directory.  That will provide the same unique logging 
environment for each webapp as Log4jCRS provides, except you lose the 
advantage of sharing one instance of Log4j.

I you are serving out of Tomcat's "webapps" directory, try changing docBase

disable directory listing in tomcat 4.1.12

[Yandell Cacton]

Hi,

I upgraded my server from Tomcat 3.3 to Tomcat 4.1.12,
and could not figure out how to disable directory
listing.

It was done by setting StaticInterceptor's listing
attribute to false in Tomcat 3.3, but it looks like
StaticInterceptor is no longer part of Tomcat 4.1.12's
server.xml?

I have read the configuration documentation on
jakarta/tomcat web site and can't find any information
re this.

Cheers,
YC

Taglib iterator (4.0.4 / 4.1.12) same code, diff output

[Jay Wright]

I have written a taglib to handle iteration, which works well when I deploy
it to tomcat 4.1.12.  When I deploy to tomcat 4.0.4, I receive an odd error.

My Iterator somehow takes on a null value somewhere between the doStartTag()
and doAfterBody() methods.  The doStartTag() correctly grabs the first item
in the Collection, but then when the doAfterBody() kicks in, the Iterator,
which is a protected instance variable, is null.

This is the case only in 4.0.4, not 4.1.12, where it functions as I'd expect
it to.

Is this a bug with 4.0.4, or is 4.1.12 doing something its not suppose to.

Thanks,
Jay

Escaped versus unescaped cookies

[Lee Grey]

I am running the same servlet on two different machines.  One is running

newbie question creating and serving a context

[James Bender]

Hi,

I'm having a really frustrating problem just creating a simple context using 
Tomcat 4 on a Linux server.

I edit server.xml in my conf directory to include:


  path="/jsp_public"
  docBase="/var/tomcat4/webapps/jsp_public"
  debug="0"
  reloadable="true" crossContext="true">
  
prefix="localhost_manager_log." suffix=".txt" timestamp="true"/>


then in /var/tomcat4/webapps/ I created the folder jsp_public as well as a 
subdirectory WEB-INF where I added empty folders "classes" and "lib" and the 
following web.xml:



	PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
	"http://java.sun.com/dtd/web-app_2_3.dtd";>



 Public JSP directory
 just trying to create a context for public 
development.

When people talk about running mulitple Tomcat instances, they are talking
about multiple JVMs, not one.  Out of the box, Tomcat doesn't support
multiple "instances" within a single JVM.

Within a single JVM, whether things like LogJ are shared or not depends on
where the classes are loaded from -- if they're inside the /WEB-INF/lib
directories, each webapp will have their own; if they are loaded from some
place like the common/lib directory, the classes will be shared.  Howver,
I understand that Log4J still supports per-webapp configuration of loggers
in the shared case if you want it.  See the Log4J docs for more info.

For more background on class loading in Tomcat, see:

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/class-loader-howto.html

I'm not a guru on the web connectors, but it sounds like you can do this.
However, grabbing the most recent connector will probably have some
performance benefits (as well as bug fixes), so you might want to grab it
anyway.

Sounds like maybe apache is running, but tomcat is not? or Tomcat is not

And this sounds like maybe you've got Apache pointing to a tomcat on
another server.

Sorry I don't have any more suggestions, but I would need more specifics
before I could even guess. For instance, you might post the relevant
lines of your apache and tomcat configuration files, and of your webapp
configuration files for tomcat.

Fwd: Install Tomcat 4.1.12 on WinXP problem ... solved by installing Microsoft Loopback Adapter

[T S]

I am writing to put closure on this subject.  Attached are the e-mails that helped me 
solve the problem.  The bottom line was that Microsoft Loopback Adapter had to be 
installed.  Detailed instructions on how to install Microsoft Loopback Adapter are 
included below. 
I owe a large "Thank You" to Greg Nieman for following this problem through to 
completion.  Thanks a lot for your help, Greg!

Greg, 
After following your detailed instructions on how to install Microsoft Loopback 
Adapter, http://localhost:8080 works when Tomcat is running!  I don't think I would 
have been able to install Microsoft Loopback Adapter without your step-by-step 
instructions.  WinXP is still new and foreign to me, I am used to using Win2000 at 
work or WinME at home. 
I have recorded the detailed output of netstat at each step, hoping that it might 
provide you some additional information that could be useful to you. 
   netstat -a -e -n -o -s -p tcp

I don't know how to say "Thank YOU" enough.  Two people wrote me with suggestions, 
each with a different suggestion.  The other person stopped giving advice after their 
first suggestion didn't work, but you continued helping me until Tomcat started.  I 
really appreciate your help.  Now I have a whole lot more to learn about Tomcat, but

apache + tomcat configuration

hi,
I am trying to integrate apache 1.3.26 and tomcat 4.0.6 on win2000 server.
After an initial configuration, I can get them going, and I can also access
all the examples' servlet through apache, I mean without giving :8080, but
I still have the following problems:
__1. in my apache error.log, every time when I access to a servlet, I would
have an error logged as:
  client denied by server configuration:
c:/tomcat/webapps/examples/web-inf
__2. in my tomcat stderr.log, every time when I start tomcat, it logs:
  mod_jk location: modules\mod_jk.dll
  Make sure it is installed corectly or  set the config location
  Using 
__3. my mod_jk.log (same location as stderr.log) is always empty.

please help, thanks.

RE: how many tomcat in a machine?

[Nicholas Orr]

Just on this point of multiple Tomcat Instances, how does the JVM fit into
all of this.
ie does Tomcat1 use JVM1 and Tomcat2 use JVM2. Or does Tomcat1 & Tomcat2 use
JVM1?

Also if you had one Tomcat Instances and 3 apps would they all share the one
instance of Log4j and its static methods or would there be three instances
of Log4j??

In simple terms, does this mean that if I have a context called "/context1",
and want all vhosts to be able to access and use it, I can just specify the
context one time in the default host and not have to worry about specifying
it for any other host in server.xml?

Good to know!  We are upgrading from 3.2.4 and it seems like the number of
processes started up with that was around 300, roughly equal to the number
of contexts we had declared, 150 hosts with two contexts each, which is why
I thought they were related.

One last question, I am going to continue to use our old compiled mod_jk
connector from tomcat 3.2.4.  We are using the Coyote/jk2 AJP 1.3 connector
in server.xml.  Is there anything wrong with this, or should I just take the
time to try to compile a new connector too?

Tomcat on a separate machine

[Lee Grey]

I have server1 running both Apache2 and an instance of Tomcat4.  I have
server2 running its own instance of Tomcat4.  The Tomcats on server1 and
server2 are running different applications.

I am currently trying to get requests for urlinone.com received by Apache at
server1 forwarded to the Tomcat at server2.  It seems like they see each
other, because, when I shut down Apache on server1, server2's log shows:

Nov 17, 2002 4:14:29 PM org.apache.jk.common.ChannelSocket processConnection
WARNING: server has closed the current connection (-1)
Nov 17, 2002 4:14:29 PM org.apache.jk.common.ChannelSocket processConnection
WARNING: server has closed the current connection (-1)

However, I don't see any indication that servlet requests are getting from
Apache on server1 to Tomcat on server2.  There is no log activity on server2
to match the requests shown at server1.

On server1, Apache httpd.conf contains, in part:

NameVirtualHost *

  LoadModule jk_module /usr/local/apache/modules/mod_jk.so

# Am I supposed to have AddModule mod_jk anywhere?  There are no AddModule
statements in this file.
JkWorkersFile /var/tomcat4/conf/jk/workers.properties
JkLogFile /var/tomcat4/logs/mod_jk.log
JkLogLevel info
JkLogStampFormat "[%a %b %d %H:%M:%S %Y]"

ServerName www.urlinone.com
ServerAlias urlinone.com
DocumentRoot /var/tomcat4/webapps/urlinone
ErrorLog /var/tomcat4/logs/urlinone-errorlog
CustomLog /var/tomcat4/logs/urlinone-access.log common
Alias / "/var/tomcat4/webapps/urlinone/"
JkMount /servlet/* server2


Server1's workers.properties file says:

worker.list=server1,server2
worker.server1.type=ajp13
worker.server1.host=192.168.1.80
worker.server1.port=8009

worker.server2.type=ajp13
worker.server2.host=192.168.1.50
worker.server2.port=8009

Server2's server.xml file says, in part:

  



  
  

  

The Apache log shows a request being successfully completed:

192.168.1.1 - - [17/Nov/2002:16:27:27 -0500] "GET /index.html HTTP/1.1" 304
0
192.168.1.1 - - [17/Nov/2002:16:27:27 -0500] "GET /urlinone.js HTTP/1.1" 304
0
192.168.1.1 - - [17/Nov/2002:16:27:27 -0500] "GET /servlet/PagePump
HTTP/1.1" 200 0

But there is no activity, as far as I can see, on server2.  Server1 is
running Red Hat 7.3 and Tomcat 4.1.12, while server2 is running Red Hat 7.2
and Tomcat 4.0.3.  I had to download all the jars at
http://jakarta.apache.org/builds/jakarta-tomcat-connectors/coyote/release/v1
.0-rc2/ to get Coyote running on server2, so I'm wondering if there is some
incompatibility there.  Despite the instructions on that page, I do not have
a jk2.properties file, nor do I have tomcat-jni.jar, because I don't think
I'm using either of those, since I'm using mod_jk.  I also don't believe
there is any need for a workers.properties file on server2, since that is
for mod_jk in Apache, right?

The only other thing, and I don't know if this is a red flag or a red
herring, is that mod_jk.log on server1 gives bursts of errors sometimes,
although 90% of the time it's when Tomcat on server2 is starting up or
shutting down.  I have seen some errors upon a request, though.  I tend to
think the problem is within my configuration, though, and that these errors
are not significant.  I include them for completeness.

You can do this by taking advantage of the "defaultHost" attribute on the
 element.  If a request comes into Tomcat with an unrecognized
host name, it is assigned automatically to the  element that is
speicified by defaultHost.

The out-of-the-box configuration uses this technique to assign all
requests for all virtual hosts to the  named "localhost", which is
the single set of webapps nested inside that host.

>  This causes way
> too many threads on startup and slows the system down.

Unless you are starting threads in your own servlets, the number of host
elements and webapps has neglible impact on the number of threads that
Tomcat starts.  That is driven primarily by how you configure your
 elements; and the connector threads that process requests are
shared across all the hosts and webapps.

> Any ideas?  We are using tomcat 4.1.12 and apache 1.3.26.

The above info is about the Tomcat side of things -- you'll need to ask
someone else about the Apache connector configuration for this to work.

If you map your filter to "/*", it can already make whatever dynamic
decisions it wants to about dealing with the request.  Therefore, it
doesn't really need to be in the container.

The only standard mechanism is to create the patterns in web.xml.

Can all vhosts share one Webapp?

[Brandon Cruz]

Can I have all my virtual hosts share one webapp?  I would like to avoid
having to declare a context for every single virtual host.  This causes way
too many threads on startup and slows the system down.

Any ideas?  We are using tomcat 4.1.12 and apache 1.3.26.

Listener Object

Hi

i have a HttpSessionListener object that is deployed in the web.xml file. At
Tomcat startup two instances of that listener class are created. Is it
normal that two instances of the listener class are created? Why? If not,
where could the second instance come from?

Thanks for your answers.

Tomcat Startup 2 errors

[Triptpal Singh Lamba]

1. I have 3 versions of Tomcat, 2 are "associated" with Jbuilder.
These 2 versions start off and give me an error described below. The
point to note is that the command window(dos) in which I  run it stays and
does not disappear.

2. Downloaded a version of Tomcat , the  port for which I have chosen as
8000. I have tried starting it from startup.bat and catalina.bat run
options.

In all cases above 1 and 2 , Tomcat is starting off - that is 100% sure. (I
can see http://localhost:portno/ page). In case 1 the tomcat server window
stays on the screen. In case 2 it disappears but I can see it is running as
a process after doing CTRL-ALT-DELETE for windows XP.

The exceptions in all cases is similar :-
Why is this exception coming and how can I remove it.

So my questions are :-
1. How do I remove the exception below.
2. In CASE 2 above, while running tomcat server ,why does the does window
not remain on screen and  disappear ( something like "echo on" should make
it remain,not go as a background process, I have tried catalina.bat start
also, Funnily the Tomcat servers with JBuilder remain on screen , this is
imp for jsp debugging later on and System.out.printlns etc . )


Thanks

Why do I have to restart the server

[chasee]

Hello all,

Running jakarta 4.0.4. Placing my servlet under ROOT\WEB-INF\classes. 

In server.xml, I uncomment the context declaration for ROOT application and make 
"reloadable" true. Everytime I modify and recompile the servlet class, the tomcat 
window print out a notice of modification of the servlet. However, whenever I try to 
invoke the servlet, the server could not find it.  I have to shutdown and restart the 
server. Any thoughts on it?

Thanks, Chasee

RE: servlet classpath

[chasee]

My thanks for your response. Actually the trouble is in finding the supporting classes 
of the servlet,not the servlet itself. My servlet is in ROOT\WEB-INF\classes, while 
the supporting classes is in a package outside of tomcat installation dir. I was 
hoping the server classloader would have no problem finding them with the help from 
"CLASSPATH". Turns out the class loader refuse to refer to the "CLASSPATH". We'd have 
to put everthing under webapp/web-inf. If any of the answerers of this question find 
my statement inproper, pls point out.

It must be so in theory, but in fact I see, that when applet request servlet
(that was already initialized) at first time, the servlet function init()
automatically called, and only after that execute servlet method doPost().
So, the Tomcat creates new instance of servlet - because I see, that the
first instance of servlet(to which were requests only from browser, not from
applet) exists parallel to the new instance().
At the following requests from applet to the servlet function init() does't
execute's and no new instances are created.

RE: servlet classpath

[Reynir Hübner]

Try putting your servlet into your webapplications lib directory, its usually under, 

Your_web_application/WEB-INF/classes (if it's not packaged) or 
Your_web_application/WEB-INF/lib (if it's packaged in a jar file).

The size of your terminal screen does not matter. 
hope it helps

My guess is you're asking about struts, but not "structs" ?
Yes you can, see http://jakarta.apache.org/struts

RE: why Tomcat 4.0.4 creates new instance of servlet, when applet make first request to servlet?

[Reynir Hübner]

If I understand you correctly I think I must say a servlet get's initialized once, 
when it's loaded (by the classloader), and then only again if it's changed.
A servlets runtime is within the scope of one request, so if you want to execute the 
same servlet twice, first to set member variables then with an applet and read from 
the member variables, I cannot see how it could be achived, exept maybe by using 
alternative methods, such as keeping the variables in servlet context, but not as 
member variables in the servlet.

Hope it helps

RE: JSP1.2 xml syntax

[Doug Blackburn]

David,
That worked. I was able to set the content type in the page directive. I
guess I was being a little stubborn since it worked on the other two
servers. Tomcat is just not so forgiving.
Thanks again.
Doug

Doug,

If you look at what you are sending to the browser - html right (the stuff
in the CDATA elements)?
yet you have the contenttype set to xml.
IE is therefore told the content type is xml, expects to receive well-formed
xml yet gets fed non-well-formed html from your jsp script and then
correctly tells you what and where the problem is.

Why don't you take the simple step and do:
response.setContentType("text/html;charset=UTF-8")

David.

David,

Thanks for you suggestion.  I just looked at the Tomcat generated
TableEntry_jsp used to process the requests. It has
response.setContentType("text/xml;charset=UTF-8").  I think that should work
fine. The only difference between that and the servlet generated by the Sun
J2ee Ref Impl Server is that charset=ISO-8859-1.

Am I missing something here?

Doug

reading beween the lines:

it seems IE it not happy because it thinks it needs to display it as XML so
it looks like a mime type setting in the header. Set it it text/html and it
should be fine :-)

How is anyone supposed to be able to offer any useful advice unless you
show us the source for a page that works in one environment but not the
other?  And show us what error messages you get when it fails?

why Tomcat 4.0.4 creates new instance of servlet, when applet make first request to servlet?

[Daniil Ivanov]

Given:
Tomcat 4.0.4 and servlet, that was already initialized when browser made
request to it.

When browser window with applet opens, applet begin periodically query the
servlet through standard method doPost. But at the first request applet to
servlet Tmcat creates a new instance to servlet, in spite of that the
servlet was initialized before.
I do't whant to have  a two instances of servlet, because applet must get
from servlet a members of servlet class, that were already changed before by
previous request from browser (not from applet).

Thanx craig.

I wonder why this is not a part of the spec, as it could be very usefull.

Is there a way of setting the url-patterns on runtime, or only in web.xml ?
