Re: Help Needed to configure servlets

[Kwok Peng Tuck]

Just deploy your .war file as AppDir  so you will have
http://covington:8080/AppDir/*.jsp or servlets
The .war file should be put under the {CATALINA_HOME}/webapps/
It will be autodeployed when tomcat is restarted. Or you can use the 
webapp manager.
Again, read the docs on how to use the webapp manager. There is even a 
tutorial on how to deploy a sample webapp with the docs.

The classes go under WEB-INF , either under classes (if they are .class
& don't forget their package if they have any), or the directory lib if
they are jars.
Define your servlet in the web.xml of your web application. How? It's in
the tomcat documentation as well as the examples that came with tomcat.

Hello,

I'm Anitha, working on JSP/Servlet.
In simple sentence...
I want to create a Directory called "AppDir" under webapps.
Then i need to configure my servlets.
The Directory Structure looks like this..

webapps
 --- AppDir -  JSP file
  --- Web-inf   - web.xml file
-- classes - My Servlet Class files

http://localhost:port/AppDir/

does not display the servlet.

Kindly help me out as to where I need to configure the servlet,
 

Application
 

Directory
with example code or a web site to help me run the servlets.

Thank you

Anitha

Missing optional package Extension...

[Eung-ju Park]

I put all required jars to WEB-INF/lib. but tomcat says missing optional
packages.
excalibur-container.jar require avalon-framework extension package. I have
all required packages.
WEB-INF/lib is incorrect place for optional packages?
Why tomcat throws exception for just optional package? I don't know about
Optional Extension Package specification.

Help to Configure Apache and Tomcat to use mod_jk!

[Hai To Thanh]

 Hi, 
 I get trouble when I try to make communication
between Tomcat and Apache. I follow following steps:
   1, I get mod_jk.so.
   2, To Configure Apache using mod_jk:
  I put the following include directive at the end
of your Apache httpd.conf file: 
  "Include /usr/local/jakarta- 
tomcat/conf/jk/mod_jk.conf".
   3, To Configuring Tomcat:
  I add the following block to your 
TOMCAT_HOME/conf/server.xml file 
   "".

 But When I type:
   #./httpd start
to start Apache Web Server then I get following error:
 
 "Starting httpd: Systax error on line 7 of
/usr/local/src/jakarta-tomcat-4.1.12/conf/auto/mod_jk.conf:
  invalid command "JkWorkersFile", perhaps mis-spelled
of defined by a module not include in the server
configuration.

Help me!

how do I invoke servlet from a servlet in different web application?

[Jason Novotny]

Hi,

   I would like to know how I can invoke a servlet in one web 
application from a servlet in another web application? Also, how would I 
do this if the other servlet is hosted in another servlet container on 
another machine?

   My goal is to provide a web application framework that other web 
applications can plug into, so that I can re-deploy the secondary web 
application while still running my main framework servlet. What are the 
potential security/performance issues associated with this?

   Finally, I see that server.xml has an option to allow for the 
reloading of web applications whose servlet classes/JSP's have changed. 
However this may be to resource consumptive on a production server-- is 
there any way I can send an "admin" command to reload servlets whose 
timestamp has changed (push rather than pull model)?

   Thanks for the help, Jason

Re: Tomcat autostart on Linux

[Mr. Cristian Romanescu]

It depends on how it's installed, also Linux distro

If you have RedHat and istalled via rpm distro, you should have in 
/etc/init.d/ a script named tomcat4 that launches Tomcat @ statup.

 4 -rwxr-xr-x1 root root 3055 Mar  4  2002 tomcat4

(I'm not also a linux expert, but I suppose that should be marked 
executable.

also you can stop/start manually invoking
/etc/init.d/tomcat4 

Here's a quick'n paste solution

tomcat4.1/apache2

[james]

Hi,

I have the following setup using a normal socket connector config :
Redhat 8
Apache 2.0.43
Tomcat 4.1.12
mod_jk2-2.0.43.so
jkjni-2.0.so

Questions:

What are the difference between the normal socket, AF unix, and JNI?
Pros/cons when to use or when not to use? I didn't see any info on this on
the jakarta site. Any pointers?
Also, I'd tried setting up the Apache/Tomcat using the JNI method but they
didn't seem to talk to each other - I followed the config examples given
on the jk2 tomcat site
(http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jk2/index.html). What is
wrong?
Thanks, James

tomcat 4.1.12 compilation error

[Nirav . Shah]

Dear All,

I am just newbie for tomcat 4.1.12 version. Recently I have installed it on
my NT Server. Now I have a problem to access classes through JSP files of
my Application.

Following is the structure of my application

webapps\myapp\*.jsp
webapps\myapp\WEB-INF\classes\*.class

Following is the error which I am getting.

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 1 in the jsp file: /checklogin.jsp

The same structure was working fine in tomcat 3.x version.

Thanks in advance :)

[Mr. Cristian Romanescu]

In my oppinion it's your application fault and not Tomcat's. It would be 
helpful to send the code snippet from place where your code throws 
NullPointer...

But first you should try to put some System.outs. out there and see 
where the code hangs...as that exception doesn't give (me) a clue about 
what's happening..

Re: tomcat 4.1.12 compilation error

[Tim Funk]

Put your custom java classes in a package and recompile.

Old class: Login
New class: fooPackage.Login
New location: webapps\myapp\WEB-INF\classes\fooPackage\Login.class

Tomcat 4 doesn't looking for classes without a package.

Have a look in the generated java file in the 
work directory that caused this exception 
(processviewfiles_dir_4.java) to find the 
corresponding location in your jsp.

If you don't see the error post the code 
around that line.

You are getting a java.lang.NullPointerException

Look for processviewfiles_dir_4.java line 133 - there is a NPE being 
thrown here. Why .. don't know.

HttpProcessor not recycling connections / bug 5181 ?

[Graham King]

	Dear all,

 I'm running Tomcat 4.0.3 with Java 1.4 on Linux, and we are getting lots of 'IOException: 
Connection reset by peer' (see stack trace at bottom of mail), which I understand is the user 
hitting 'stop' or closing the window before the load completes.

After several hours of running our server will run out of request processors (well actually we put 
maxProcessors at 1024 so the site falls over with 'OutOfMemoryError: unable to create native thread' 
but that's just whilst we try and fix this).

I believe this is because StandardWrapperValve is catching the IOException, so it never gets back up 
to HttpProcessor, so the processor never gets recycled.

I saw in a comment right at the bottom of here 
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=5181 that this is fixed in 4.0.4b1, but I could 
not find any other information about that in the release notes, bugzilla or mail list archives.

 We can't use the 4.1.X branch because we symlink to content outside the webapp directory and the 
allowLinking doesn't work for us (in 4.1.12 at least).

 So what I am asking is:

 - Does anyone know of a recorded problem with recycling processors in 4.0.3 and if so is this 
definately fixed in later versions of 4.0.X ?
 And:
 - Has anyone else experienced something like this and is my analysis way off mark ?

 Many thanks,
 Graham.

tomcat or java problem?

[chad kellerman]

Hello,

I am running tomcat 4.0.X with Java 1.4.1. on a red hat 6.2 apache
1.3.x.

 I am using the WarpConnector to allow tomcat and apache to
communicate and for Virtual Hosts.  I have a few ( about 16) Virtual
Hosts on the box.

 What I am noticing is that when tomcat starts and the warp
connection gets estatblished by localhost on port 8008.

 
[org.apache.catalina.connector.warp.WarpConnector] Connection from
/127.0.0.1:3952 to /127.0.0.1:8008


 But it apears that the connection opens eventhough a request  has
not been made.  Then the connection never closes.

Is this a bug with the Warp Connector or is it a config problem with
java or tomcat?

Thansk for the help.

Chad

USING SSL with VIRTUAL HOST and TOMCAT STANDALONE

[Donie Kelly]

Hi all
I'm trying to configure my server.xml with multiple hosts on Tomcat 4.0.4
and I want to use a different SSL certificate for each host entry. 

I AM NOT USING APACHE! JUST TOMCAT STANDALONE (sorry for
shouting but this is important)

Does anybody have an example of how to do this? I'd really appreciate a
simple HOW-TO. I'd also be interested in how the IP addresses are configured
on the machine. Do I need to always use the DNS name to access the protected
hosts (DNS name is stored in certificate). What happens if I use the IP
address when the host is protected by SSL?

Thanks for the help
Donie

Mmmm, yes, it's kinda bogus. A case where a processor wouldn't be 
recycled is if an exception is *not* caught (the thread would get 
killed). There's still a hypothetical bug with recycling of the 
processors that has been reported once in a while, but that no committer 
has ever been able to reproduce, except in conjunction with garbage 
collection peaks.

You should reorganize your setup to make your webapps look like real 
webapps, and upgrade to 4.1.x.

Send code 401 instead of 403

[Johann Uhrmann]

Hi,

when using basic authentication with tomcat, tomcat sends a 401 response
code if the user is accessing the page for the first time.

This makes the browser show a login window and retry the request with
the username/password provided by the user.

However, if there is already a username and password in the request,
then tomcat answers with a 403 code which does not result in a login
window.

Unfortunately, if the user makes a typo when he/she tries to log in
there is no chance to make another try except restarting the web
browser.

Does tomcat provide any mechanism to make it return 401 instead of 403?
(except the hack of specifying a user based 403 jsp and make it return
401)

Thanks,

Hans

the filter is only applied on teh original request, not for forward() or

 Ah yes I wasn't thinking it through clearly. What then did you mean in your comment on bug 5181 ?

 Russell Edens says:
---
After walking through the code, it appears (to someone not familiar with the
source) that this exception prevents the recycle of the HttpProcessor.  The net
effect is that once maxProcessors is exceeded the server can never accept
requests again.
---

 and you respond:

--- Additional Comments From Remy Maucherat 2002-03-21 16:13 ---

This is a bug with JDK 1.4.
The processor not being recycled in that particular case has been fixed in
4.0.4-b1.


 What did you mean ?

Short answer: nothing

Tomcat sends that pages with response code 200. I consider this a bug.

If You want tomcat to send You 401-page with a 401 code You have to
use a JSP which sets the response code manually:

...
<% response.setStatus(response.SC_UNAUTHORIZED);
   response.setHeader("WWW-Authenticate", "BASIC realm=\"restricted\"");
%>
...

It is a hack but at least it is working.

RE: Apache-Tomcat

[Turner, John]

I only know the inelegant, brute force way, which is to check the request
object for the request type, and if it's "http" when it should be "https",
do a redirect to the same URL but with "https" prepended.

There's probably a much more robust and correct way to do this using Tomcat
security restrictions and realms, but I haven't worked with them that much,
so I don't want to give you wrong information.  Lots of people on the list
have done this, though, so perhaps the best way to proceed would be to start
a new thread with a new subject about restricting particular URLs to SSL.

RE: Apache+Tomcat Configuration problems

[Turner, John]

Yup, ditto Milt and Robert.  You've got JK directives but you're loading
JK2.  To get rid of your Apache config error, use mod_jk.so instead of
mod_jk2.so, or keep mod_jk2.so and change your config to a JK2 config.

Are you sure you have CATALINA_HOME set correctly?

See javax.servlet.ServletRequest.isSecure()

 This should do it:

 if ( request.isSecure() ) {
// All is well
 }
 else {
// Redirect to https site
 }

RE: Help to Configure Apache and Tomcat to use mod_jk!

[Turner, John]

You have to load the module into Apache before you can use it.

Look in httpd.conf for lines that look like this:

LoadModule 

Then add one that looks like this:

LoadModule jk_module wherever_you_put_it/mod_jk.so

Thanks, but I think there is a "better" way to do it, such that the request
never even gets to the servlet or JSP page if it isn't secure when it should
be.  I just don't know it.

RE: Help Needed to configure servlets

[Shapira, Yoav]

Hi,

>webapps
>   --- AppDir -  JSP file
>--- Web-inf   - web.xml file
>  -- classes - My Servlet Class files
>
>http://localhost:port/AppDir/

In the above configuration, if you have the invoker servlet mapping
enabled in $CATALINA_HOME/conf/web.xml:

http://localhost:port/AppDir/servlet/ will invoke your
servlet
http://localhost:port/AppDir/your.jsp will invoke your JSP file

If you add the following to your web.xml:

  myservlet
  your.servlet.class



  myservlet
  /MyServlet


Then your servlet will be accessible (without needing the invoker
servlet) at:
http://localhost:port/AppDir/MyServlet

Hi,

We are using JVM1.4 Logger APIs in our servlet application deployed in
Tomcat4.0 container to log messages into a file.

On Unix platforms, the log file doesn't get created, though the
application using Logger objects does not throw any exceptions.
However, the same code works on other platforms like WinXP.

Appreciate an early response.

Dear All,

I am just newbie for tomcat 4.1.12 version. Recently I have installed it on
my NT Server. Now I have a problem to access classes through JSP files of
my Application.

Following is the structure of my application

webapps\myapp\*.jsp
webapps\myapp\WEB-INF\classes\*.class

Following is the error which I am getting.

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 1 in the jsp file: /checklogin.jsp

An error occurred at line: 1 in the jsp file: /checklogin.jsp

The same structure was working fine in tomcat 3.x version.

VerifyError when creating action

[Steinar Bang]

Platform: Intel PIII, RedHat 7.2, apache 1.3.20, ajp1.3
  tomcat 4.1.12, BlackDown Java SDK 1.3.1

When I run with tomcat 3.3 my webapp run as expected, but when I try
it with tomcat 4.1.12, I get a VerifyError when creating one of the
webapp's Action beans.  The error output is attached to the end of
this message.

I've searched www.google.com for this problem, and I've found that
some people have had problems with custom tags when changing to
tomcat4, but I haven't found anyone having problems with actions.

I have cleaned away the webapp, rebuilt it, and stopped and started
tomcat, to make sure it hadn't cached a broken .class file.

The  definition from struts-config.xml, is:


  


Has anyone seen a similar problem?  Does anyone know what to do to fix
it?

Thanx!

tomcat4, which ajp1.3 connector to use? (Coyote? plain?)

[Steinar Bang]

Platform: Intel PIII, RedHat 7.2, apache 1.3.20, ajp1.3
  tomcat 4.1.12, BlackDown Java SDK 1.3.1

The tomcat4 server.xml file came with the Coyote/JK2 Ajp 1.3 Connector
enabled and the normal(?) Ajp 1.3 connector disabled (the class is
org.apache.ajp.tomcat4.Ajp13Connector).

I had to disable the Coyote connector and enable the normal connector
to be able to make things work.

Is this to be expected?  Or would it be preferrable if I would be able
to make tomcat/apache use the Coyote connector?

Thanx!

Re: Tomcat Scalability - Long

[Glenn Nielsen]

I have the following in production:

Tomcat 4.1, JDK 1.3.1, and MySQL on a Dual CPU Sun 250 app server and Apache
using mod_jk 1.2 on a separate server. We are now getting 4 weeks continuous uptime.
I stop and restart Tomcat once each month because the minimum memory the java heap
uses over time increases.  This is on a site handling 30k Tomcat requests per day.
With peak loads of 5k-6k Tomcat requests per hour.

When scaling Tomcat there are many issues to address when tuning performance.

I would suggest learning more about how the JVM does garbage collection and
test different Java startup args related to jvm stack size, etc.  Try starting
Tomcat with the java arg "-verbose:gc", this will collect GC data which can
help you when tuning the JVM memory usage.

You might also want to profile your applicaiton using OptimizeIt or JProbe
to see if it is the source of the problem.

And of course the performance tuning should be done on test servers which
are as close as possible to your production environment and with a load
that simulates your site usage.

Consider upgrading to Tomcat 4.1.  Especially if your site uses JSP.
Jasper 2 which comes with Tocmat 4.1 significantly improves performance
of JSP.

One final note, I would not set reloadable=true on a production system.
That adds alot of overhead.  The reloadable option is really there only
to make development easier.

Regards,

Glenn

Brandon Cruz wrote:

Does anyone have any solid information about the scalability of Tomcat?  It
seems very limiting to me, but that is hopefully due to improper
configuration.  Here is our situation and what seems to be happening under a
small amount of stress.

---About our Environment---

PIII 1.0Ghz
512 Meg Ram
Linux RedHat 7.1
MySQL Database
Apache 1.3.x
mod_jk - logging turned all the way down
Tomcat 3.2.4 - contexts *are* reloadable right now
SUN JDK 1.3.1_01

---About our Application---

Our Application is a content management tool that reads and writes to the
MySQL Database and reads and writes files.  All the pages within this
application are served by Tomcat 3.2.4.  About 80-120 people per day log
into this application and spend anywhere from 10 minutes to one hour working
on the application.  At any given time there are between 15 and 50 active
database connections.

---What we are seeing---

Tomcat needs to be restarted every few days.  If we don't restart it, it
seems tomcat eventually locks up and does not respond at all.  No errors or
anything are reported, it just will not respond.  Apache continues to work
during this time and all static HTML pages are accessible.

CPU - The processor usage seems to slowly increase as time goes on.  After
about one day, it seems one java process uses 30% of available CPU or more,
depending on whether users are performing operations or not.  When nobody is
doing anything, the processer still seems to be sitting around 30% until
tomcat is restarted.  This seems to cap after three to five days and not
increase too much more.

RAM - This slowly increases and never stops increasing.  We do not have any
special parameters set for the VM when it starts, but this does not seem to
matter.  The RAM gets up to about 135 MB after four or five days, but would
continue to grow if tomcat were not allowed.


Can anyone explain this behavior, talk about the scalability of Tomcat, or
provide any similar working solutions that perform better than this?  Is it
normal, should we just throw more hardware at it?  Are there configuration
parameters that can be used to increase performance, such as set
reloadable=false in all contexts?  Would we get better performance if we
upgraded to 4.x, or would that just be more work for little improvement?

RE: HTTP Connection Pool grows continuously

[Michael . Bombyk]

If I set a maxProcessors value, Tomcat gives me new connection threads until
it reaches the limit, and then connection requests fail. 

The high timeout value is an end user requirement for the app. In any case,
I know that Tomcat is allocating many more threads - upwards of a thousand -
than I ever have concurrently connected users.  It is almost as if threads
are not being reused. I know that in earlier releases of Tomcat, it was
necessary to explicitly configure pooling in server.xml, but after 4.0 it is
the default (and only) option. 

What would be very useful is an explanation of exactly how the Tomcat
connection pooling logic is supposed to work in release 4.0.

jspc pre-compiled pages distributed with .war file?

[Thomas Heller]

hi there,

i am migrating my projects from php to java and began to set up a
development server that ideally does all the dev work once a project is
marked release i just call an ant task to deploy the project to one or more
(load balanced) production servers.

i have written an ant build.xml to compile my webapp and to put everything i
need into "mywebapp.war". thats working very fine and i can just deploy that
.war to a tomcat server without any problems.

now, i have setup another ant task to precompile every jsp file using jasper
(ant task "jspc"). thats working perfectly fine and i have loads of
index_jsp.java, etc files. now i compile those to .class files and i would
like to distribute them inside the .war file so that the tomcat server
itself doesnt need to compile anything by himself. _Ideally_ i'd like to
exclude _any_ .jsp file in the .war file and just include the compiled
jsp.class files.

but i wonder ... tomcat somehow doesnt really know what i'm sending him and
he doesnt recognize any of the precompiled pages. how do i tell tomcat to
use the precompiled pages in the .war instead of compiling them himself?

i know i can write this it into my web.xml


index_jsp

  my.package.jsp.index_jsp




index_jsp
/index.jsp


but somehow i dont like it this way, but i would rather use this instead of
putting jsp files into the .war file. would be cool if tomcat would do
something like this by himself when he finds *_jsp.class in a
/WEB-INF/precompiled directory.

Anyways maybe tomcat has some support for what i'm trying to find and i just
can't find it? Comments welcome

Greetings,
Thomas

The above to me suggests that the initial value could be 0.  The above
doesn't force pre-creation of any connections on server startup.

Try setting the relevant debug="0" statements to debug="99" in your
$CATALINA_HOME/conf/server.xml.  Then you should get a lot more
information on what tomcat is trying to do and any errors it may run
into.

[Shapira, Yoav]

Hi,

>Did you mean setting maxWait to 0 ?

No.  I meant that setting maxActive to 5, maxIdle to 3, and maxWait to
-1 does not mean there will be 3 connections on startup.  

It's up to the connection pool implementation to decide if it wants to
pre-create the connections on startup, or not.  Some implementations may
expose a configuration parameter so that you can tell them whether to be
greedy.  

Alternatively, you could ask for as many connections as your maxIdle
will allow on startup, so that when your first real DB calls come the
connections are already created.

Re: Tag object pooling and immutability in the servlet spec

[Glenn Nielsen]

Mr. Tomcat wrote:

Is there a way to turn off tag object pooling?  Object pooling was a
cool performance technique in earlier versions of Java, but now object
creation is very fast, so it no longer serves a performance function,
and it introduces extra complexity into tag object design.  Is this
misfeature going to be phased out?



In more recent JVM's object creation is faster, but those objects also
need to be garbage collected later.  Large numbers of objects
requiring GC can significantly degrade performance. The above statement
is a generalization that doesn't apply in all cases.

In Jasper 2 custom JSP tag pooling provides a huge boost in performance
for JSP pages which use custom tags. Request latency for JSP pages which
use custom tags was reduced significantly and the system can now scale to
handle larger numbers of concurrent requests.  Before upgrading to
Jasper 2 we had upgraded the hardware from single to dual cpu's and
tripled the system ram.  We still had some scaling problems.  Upgrading
to Jasper 2 a few weeks later solved are problems.  It improved performance
as much or more than the hardware upgrade. (The site uses alot of JSP pages
with custom tags).

This is on Sun sparc's running Solaris with JDK 1.3.1.

I'll let someone else address your other issue.

Regards,

Glenn


Also, on the immutable object topic, it seems that it would be better to
have all the initialization of servlets and filters done in the
constructor, not by calling an init function.  If everything could be
set in the constructor, then all instance fields could be private final,
meaning that the servlet or filter object could be immutable, and
therefore known to be threadsafe, which is an issue with servlets.  Any
chance of these changes happening in future releases of the servlet
spec?

Thanks

Re: Tomcat Scalability - Long

  I would say Tomcat 4.1.x probably would be good for you mainly if you
uses lots of Taglibs, if they actually will work on it.
  Btw, I'm still using 4.0.x... how everybody is doing with 4.1.x? I
heard is too much buggy for production right now.

Virtual Hosts

[Curt LeCaptain]

Okay... so, I've redone my complete Tomcat/Apache setup according to
instructions on John Turner's website:

http://www.johnturner.com/howto/apache1-tomcat404-howto.html

Everything works as it should! :)

Now... I'm completely baffled as to how to set up a virtual host in
server.xml, I'm not exactly sure how to setup the elements and such to get
directories to work.

IE, I want a virtual host called "dev.infinity-tech.com" within there, where
JSP's can be launched from the document root of that site
(/www/docs/dev.infinity-tech.com) and servlets can be launched from a folder
within that directory.  If someone could help me out, or point me in a
direction to figure this out, please, let me know! :)

4.1.x In Production [Was: Re: Tomcat Scalability - Long]

[Shapira, Yoav]

Hi,

We're using 4.1.10-LE and 4.1.12-LE in production.  It's been good and
stable, except for one bug, but it's an annoying one: something in our
HTTP headers trips the 32K buffer size limit, and so we get an
ArrayIndexOutOfBounds exception from one of the internal Coyote classes
sometimes.

The good news is that if you look closely at the test milestone from
yesterday, 4.1.13, there's an item addressing the above ;)  Buffer size
increased to 48K.  I downloaded and setup a couple of 4.1.13 test
servers yesterday and I'm having our QA team run some tests against them
to attempt to duplicate the exception above.  So far, so good, no
exception.

I'd be interested to hear if other people have seen the above exception
when using 4.1.x.

Re: Tomcat and 401 custom page how?

[Kristján Bjarni Guðmundsson]

Yes you are right I looked into the bug database (should have done that 
first)

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=10373
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=13430

This bug has been around forever, and will probably never be fixed it 
seems according to the developers.

The hack only works for jsp pages, but doesn't work in servlets (anyone 
know why?), Tomcat ignores whatever you write out
to the stream and puts in it's own standard message.

This bug means you can't have professional looking web applications on 
Tomcat, I guess I have look
into some other web applications solutions, too bad I kinda like Tomcat.

RE: Virtual Hosts

[Turner, John]

Glad I could help.  

Check the documentation for the Host container:

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html

...and the documentation for the Context container:

http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/context.html

Basically, a default Tomcat install has a single Virtual Host (localhost)
with a single webapp (/examples).  So setup a new Host container that mimics
the one for localhost, and setup a ROOT Context container for your webapp
within the new Host container.

On the Apache side, setup a normal Apache VirtualHost, and in that
VirtualHost container, put two JkMount statements to map *.jsp and /servlet
to ajp13.  In workers.properties, duplicate the setup you have for
localhost, and change .host to the same name as the virtual host in Apache
and the new Host container in server.xml.

That should get you started.

John

Re: Virtual Hosts

[Curt LeCaptain]

Now, what I'm wondering, is since (according to your HOWTO) Tomcat is setup
to create the  directive for Apache, will setting up just my
server.xml do it for me, or will I need to setup Apache also?

RE: Virtual Hosts

[Turner, John]

Nope, just setting up server.xml should be enough.  You will need to restart
Tomcat to regen a new mod_jk.conf, then either restart apache or do
`APACHE_HOME/bin/apachectl graceful`.

RE: jspc pre-compiled pages distributed with .war file?

[John Trollinger]

The jspc command does not put "real" package names on the jsp.class
files.  What happens is each jsp page gets its own classloader so if you
have 2 index.jsp files they will still run.  To do what you want to do
you have to have each jsp generated .java file have a "real" package
name so that when you deploy the class files to tomcat it can resolve
the classes correctly.

There have been a few threads on both this and the developer list about
work arounds to this.. Don't have the links.. But I suggest you try
there.

Also there is an option on jspc for jasper that will create the web.xml
fragment for all the mappings for the jsp servlets.

  I created an ANT script to generate the class files, and I'm with the
same problemas Thomas have. But about this jspc option to generate
web.xml... I think ant doesn't support it, does it?
  (I'm using Ant 1.5)

I noticed you have the following code in your server.xml file within your

RE: JNDI Datasource is null, again

[Short, Dave]

In the past, I've found that I received this type of exception when any of
my connection parameters were wrong (username/password, driver name , etc.).
I'd suggest you review connection parameters carefully to make sure that
isn't the problem.

You do have your JDBC diver class jar file loaded in your tomcat\common\lib
directory, correct?

JDBC error only on non-local URL

[Greg Bullough]

I've set up the MySQL example in the JNDI
Datasource HOW-TO located in
.../tomcat-docs/jndi-datasource-examples-howto.html

Works great called from a local browser on
URL http://localhost:8080/DBTest/DBtest.jsp

Works great called from a local browser on
URL http://myexternalname:8080/DBTest/DBtest.jsp

Works great called from a different machine in the same
domain on  URL http://myexternalname:8080/DBTest/DBtest.jsp

But throws a java.sql.SQLException: Cannot load JDBC driver class 'null'
if I call it from a different machine in the same domain via a fully-
qualified URL of the form 
http://myexternalname.mydomain.com:8080/DBTest?DBtest.jsp

Adding a bit of debug trace info shows me  that it happened on the
ds.GetConnection() after the ctxLookup has set ds to some non-null value.

Any insights as to why the fully-qualified URL on the page should
make a difference this deep into the code? I'm thinking some sort
of security settings. Once again, the configuration and code is
basically verbatim copied from the HOWTO. Tomcat 4.1.12-LE

In the past, I've found that I received this type of exception when any of
my connection parameters were wrong (username/password, driver name ,
etc.).
I'd suggest you review connection parameters carefully to make sure that
isn't the problem.

You do have your JDBC diver class jar file loaded in your tomcat\common\lib

jvm_route in jsessionid

[johannes . grumboeck]

Hi everybody,

If I do loadbalacing with Apache 2.0.40, mod_jk 1.2.0 und Tomcat 4.1.10
I have to enter the ajp13-connector-name into the "jvm_route" parameter of
each tomcat engine (in server.xml).

mod_jk does the session-true balancing with the help of the jvm_route which
is somehow encoded into the jsessionid.

Can anybody tell me how the jvm_route is encoded into the sessionid, and
secondly when is it encoded: 1) when the sessionid is the first time
created
or 2) when I use the function encodeURL() ?

thanks in advance and
best regards,

New to war files

[Trickel, EE Erik (3946)]

I am new to using war files, and I have run into a problem.  I tried
searching the archives and I didn't see an answer to my problem.  I am
building the war file from an ant build script.  I have tested this on the
pre-war directory and it works fine.  The issue I am running into involves a
jsp page and a server side include file.  I am using a relative path with
the .. pointer.  So It looks something like this

search/search.jsp
<%@include file="../general/globalvars.jsp"%>

I am running on win2k server, Tomcat as a service, 

I have verified the file was included in the war, and even changed the
context to use the extracted directory.  Any help would be great.


Thank you,
Erik

Form-based authentication assistance

[Scott Purcell]

Hello,

I am trying to understand how the built-in forms validation works in tomcat 4.03 on 
win.

I believe that I have my web.xml file correct, (below). All appears good. If I put in 
a bad username and passoword, I go to the error page, but if I successed, it throws up 
an error, [Invalid direct reference to form login page].

Which makes sense, I guess it is submitting it back and the URL shows 
[http://localhost/altercast/j_security_check]

How do I forward the user to a good login page, if they pass the basic authentication?

My page is /loginpage.html
// here it is:

Hi,

>Did you mean setting maxWait to 0 ?

No.  I meant that setting maxActive to 5, maxIdle to 3, and maxWait to
-1 does not mean there will be 3 connections on startup.  

It's up to the connection pool implementation to decide if it wants to
pre-create the connections on startup, or not.  Some implementations may
expose a configuration parameter so that you can tell them whether to be
greedy.  

Alternatively, you could ask for as many connections as your maxIdle
will allow on startup, so that when your first real DB calls come the
connections are already created.

JSP's and J2SDK1.4 assert statement

[Oliver Jonas]

Form-based authentication assistanceHi,

I'm trying to use the new assert statement in my JSP's. So, I set my
JAVA_OPTS environment variable to "-source 1.4 -enableassertions" (w/o
quotes) but the catalina startup script doesn't like it. And exists
immediately without starting Tomcat.

I'm using Tomcat 4.1.12-LE on Windows 2000.

Has anyone managed to make use of asserts in JSP pages?

No.  Your assumption that it "no longer serves a performance function" is
not correct.

Just as an example of why it still matters, consider something like this
(using the JSTL iteration tag):


  


The tag reuse mechanisms allow a page compiler to create one instance of

The constructor of a Servlet (or Filter) doesn't have access to the
ServletConfig (or FilterConfig) object, so it cannot acquire
initialization parameters, a reference to the ServletContext instance, or
anything like that.

Because javax.servlet.Servlet and javax.servlet.Filter are interfaces (not
classes), you can't declare constructors in them.  Therefore, the servlet
spec requires that there be a zero-args constructor available so that
instances can be dynamically instantiated.

Would it be possible to require servlets and filters to have a constructor
that takes a ServletConfig (or FilterConfig) argument?  Sure ... at the
cost of breaking every Servlet or Filter that has ever been written.
Doesn't seem like a smart idea to implement something that is purely
cosmetic, and wouldn't change the actual functionality provided by the
container.  There's much more important things for the spec to address.

In workers.properties, set worker.worker-name.host to the FQDN of host 2.

VirtualHost in Apache should be whatever virtual host is in the URL, not the
hostname of the machine hosting Tomcat.  Ditto in server.xml...the Host
container should have the name of the virtual host in the URL.

Which implies you're putting code in scriptlets, right?  Sheesh ...

Java code to implement business logic belongs in Java classes, not
intermixed with your presentation markup in a JSP page.

RE: JSP's and J2SDK1.4 assert statement

[Oliver Jonas]

Hi Craig,

I also tried CATALINA_OPTS... same thing happens. Thinking about it "-source
1.4" isn't actually a valid option for "java", only for "javac". (Maybe
that's why it fails because it starts fine if I only put "-enableassertions"
in JAVA_OPTS.

So I guess I need to tell Jasper to use the option "-source 1.4".


Any ideas how to?

Thanks,
Oliver.

PS: Using JSP's only for HTML presentation... but would still like to have
asserts to make sure values returned by the underlying Java API are valid.

Which implies you're putting code in scriptlets, right?  Sheesh ...

Java code to implement business logic belongs in Java classes, not
intermixed with your presentation markup in a JSP page.

   Subject:Tomcat JSPs not loading

Greetings,

I'm having problems with a Tomcat 4.0.4 installation on Win2k.
Someone else within the company says they installed this binary
distribution from a standard Tomcat installer.  It appears that
one of the obvious things changed is the port for the HttpConnector
has been changed to port 9080.

For some reason JSP files do not load. I've tried accessing
the example JSP pages and they do not load.  The servlet examples
seem to work ok, but once you try to access the JSP pages,
the servlet examples hang as well.  There don't appear to be any
related errors.  The only thing that looks odd in the logs is access
to the JSP pages returns 302 status codes.  I believe this refers
to a redirect.

Any ideas on what I should look for? 

Thanks in advance,

Eric

Re: jspc pre-compiled pages distributed with .war file?

[Andy Wagg]

Tomcat requires the servlet and servlet mappings in the web.xml, this is 
the way it works. Essentially, servlets are generated for the jsp pages. 
I modified my web application this week to precompile the jsp files and 
no longer include these in my war.

The JspC compiler when used with the -webapp option, also allows the use 
of either -webxml or -webinc to generate a complete web.xml file or just 
the servlet and servlet mappings to be included. I found I couldnt do 
this using the ant jspc command, but rather used a java task to run the 
jspc command.

My generated .java classes were then compiled with all my other classes 
and put in the war.

Andy.

hi there,

i am migrating my projects from php to java and began to set up a
development server that ideally does all the dev work once a project is
marked release i just call an ant task to deploy the project to one or more
(load balanced) production servers.

i have written an ant build.xml to compile my webapp and to put everything i
need into "mywebapp.war". thats working very fine and i can just deploy that
.war to a tomcat server without any problems.

now, i have setup another ant task to precompile every jsp file using jasper
(ant task "jspc"). thats working perfectly fine and i have loads of
index_jsp.java, etc files. now i compile those to .class files and i would
like to distribute them inside the .war file so that the tomcat server
itself doesnt need to compile anything by himself. _Ideally_ i'd like to
exclude _any_ .jsp file in the .war file and just include the compiled
jsp.class files.

but i wonder ... tomcat somehow doesnt really know what i'm sending him and
he doesnt recognize any of the precompiled pages. how do i tell tomcat to
use the precompiled pages in the .war instead of compiling them himself?

i know i can write this it into my web.xml


index_jsp

  my.package.jsp.index_jsp




index_jsp
/index.jsp


but somehow i dont like it this way, but i would rather use this instead of
putting jsp files into the .war file. would be cool if tomcat would do
something like this by himself when he finds *_jsp.class in a
/WEB-INF/precompiled directory.

Anyways maybe tomcat has some support for what i'm trying to find and i just
can't find it? Comments welcome

Greetings,
Thomas

Question about appBase...


What exactly would I set that to?

I've got dev.infinity-tech.com as what I want for my website... I want

Is that what I would set as my appBase?

Also, I'm a bit shaky on what the ROOT context is.

RE: Virtual Hosts

[Shapira, Yoav]

Hi,

>What exactly would I set that to?

Depends on what you want to accomplish.  We typically leave it as
"webapps" and specify different (absolute) docBases for individual
webapps as necessary.

If you have several webapps under the same location, you can change just
the appBase to point to that location instead of changing each webapp's
docBase attribute.

>I've got dev.infinity-tech.com as what I want for my website... I want
>everything served out of /www/docs/dev.infinity-tech.com/

Do you have just one webapp or many?  

>Is that what I would set as my appBase?

If you have many webapps, all under /www/docs/dev.infinity-tech.com, and
you don't want to set the docBase for each webapp to that location, then
yes, you would set the above as your appBase.

>Also, I'm a bit shaky on what the ROOT context is.

It's simply the webapp with no context name.  The one that's accessed
when the user points his/her browser to your appBase (in the default
configuration).  If you start changing the appBase and docBases, you can
use the ROOT context for other things.

Tomcat gives you many ways to specify where the documents for your
webapps are located.

I assume you've already read the relevant tomcat docs.  If not, look at
the host reference at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/host.html
and the context reference at
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/context.html

Servlet running/not running

[SAmhed]

Hi all,

I'm a newbie at Tomcat and would appreciate the help.

I have installed Tomcat 4.1.12. I have this directory structure for a
servlet. C:\Tomcat\webapps\myApp\WEB-INF\classes and the servlet name is
test. OK. When I try to see this servlet by
http://localhost:8080/myApp/servlet/test, I get this; "The requested
resource (/myApp/servlet/test) is not available. Now, if I copy the
test.class file to C:\Tomcat\webapps\examples\WEB-INF\classes, it works
(http://localhost:8080/examples/servlet/test), which leads me to believe
that I need to do some tweaking with the configuration.

THREAT: I posted this question yesterday too but didn't get any reply.
Understand that I'm a Microsoft programmer trying to get on board with you
Java people and if you don't help me, I'll go back to working on good ol'
IIS.

 It's more of a threat to IIS actually :)

Tomcat is case sensitive.  Your directory must be Tomcat
4.1/webapps/servlet1/WEB-INF/classes/st/Servlet1.class  the web-inf must be
WEB-INF.  Windows Explorer has a problem with this.  Use the command line if
need be.  Also, I assume your servlet is in a package called st.  You must
invoke your servlet by the fully qualified name (st.Servlet1) unless you add
a  tag to your servlet1/WEB-INF/web.xml file.

4.1.12 comes with the default invoker servlet mapping turned off for
security.  The release notes have the full details.

Uncomment the  element for the invoker servlet in
$CATALINA_HOME/conf/web.xml to make the above work.

Better yet, declare a mapping for your servlet by adding the following
to your web.xml (the one in myApp/WEB-INF):


  testServletName
  test



  testServletName
  /Test


And then access your servlet by
http://localhost:8080/myApp/Test

This way, you don't have to have the invoker servlet.

Re: Apache 1.3.23 and Tomcat 4 - connect??

[John B. Moore]

Still encountering some issues..

First I am following the howto's by John Turner.. (thanks much..BTW)

   Before doing anything I'm seeing the following output when starting 
tomcat

===
INFO: Initializing Coyote HTTP/1.1 on port 8080
mod_jk location: libexec/mod_jk.so
Make sure it is installed correctly or set the config location
Using 
.
INFO: JK2: ajp13 listening on tcp port 8009
..
INFO: Jk running ID=0 time 13/70 config-/var/tomcat4/conf/jk2.properties
===

Adding the recomending lines to the server.xml and creating the 
workers.properties file does not create the /auto/mod_jk.conf file I was 
previously expecting.. (good)

But now I see that I have JK2 on the port that I want only JK to be 
running..??? yes ???

I find the following in my server.xml


===


 port="8009" minProcessors="5" maxProcessors="75"
 enableLookups="true" redirectPort="8443"
 acceptCount="10" debug="0" connectionTimeout="2"
 useURIValidationHack="false"
 
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>


so I comment it out and uncomment the following


 

 port="8009" minProcessors="5" maxProcessors="75"
 acceptCount="10" debug="0"/>

   
but now I get the following error when restarting tomcat...


ServerLifecycleListener: createMBeans: MBeansException
java.lang.Exception: ManagedBean is not found with Ajp13Connector



if I uncomment both I still get this error.. (so it has nothing to do 
with the JK2 connector even though I don't think there can be two 
connectors on the same port, which lead me to comment out the JK2 one)

 Suggestions appreciated...

 Thanks, John..

Bug?

[chad kellerman]

Hey everyone,

  Check this out.
  So I am getting this java exception:
 2002-10-25 13:53:40
[org.apache.catalina.connector.warp.WarpConnection] Exception on socket
java.io.IOException: Premature packet header end 
at
org.apache.catalina.connector.warp.WarpConnection.recv(WarpConnection.java:237)

at
org.apache.catalina.connector.warp.WarpConnection.run(WarpConnection.java:194)
at java.lang.Thread.run(Thread.java:536)

  Now I know I couldn't be the only one experiencing this error.  I
checked everywhere, where I eventually ended up at apache-bugzilla

http://issues.apache.org/bugzilla/show_bug.cgi?id=4547

If you read the thread you'll see that it has been resolved and it
was a duplicate bug.  And it lists the link to the other bug:

http://issues.apache.org/bugzilla/show_bug.cgi?id=4545


But,  The two are completely different.  One is a ssl key bug and the
other is a socket exception



Am I missing something??

I am running the newest tomcat 4.0.6  on apache 1.3.2X with the newest
jvm on redhat 6.2.

I get the above error then apache freezes up?

Any every have this happen?



Does this bug need to be reopened??  Never been in this situation and I
don't know how to proceed.  Any help would be greatly appreciated.

Sincerely,
Chad
