What is the common way to install a new version of a war file ?

My experience is, that I have to stop tomcat, delete the .../webapps/app_dir
copy a new app_dir.war to .../webapps and start tomcat.

But this is not appropriate on a production system.

I do not want to restart tomcat.

What will be a better solution ?

Re: Tomcat 4.0.x memory leak (not javac)

2003-12-01 Thread Abhijeet Selukar

Hi,
I am also facing the same problem of memory leakage. I have posted on mail about this 
on 19th Nov too... 

I had contacted to the support people where our web application is hosted. I had got 
few suggestions. According to their suggestion - 
1. I increased the heapsize in catalina.sh file.
2. I have also tried to increase the file descriptor size.

Increaing the file descriptor size helped me at some extent. It stopped the frequent 
exceptions in Tomcat - catalina but occasionaly I am still gettng same exceptions.
I would really like to have some more suggestions.

   Thanks Dave.  If anyone could provide some more information on this,
   that would be helpful.  I would really like to fix it because it's 
   really annoying me.  We have two CRITICAL web applications on one 
   server.  We don't want to have to continually down the entire tomcat
   server just to reload a webapp.
  
  
   Bugs have been filed for this issue against 4.1.x and they have been 
   marked as WONTFIX.  Best to try to reproduce the problem on 5.0.x and 
   if the bug still exists there, file a report in bugzilla if one does 
   not already exist.
  
  
   Where can I find this information?  Is there a bugzilla for tomcat or 
   something?  If so, I would like to go there so I can see if there's 
   any information indicating where in the code it would be.  I could go 
   searching myself, but I've never dove into the Tomcat code before! :)
   
   
   Could you post the bugid or even a link to the bug-report? i'm also 
   interested in the porblem.
   
   I would also be interested in a description of the javac-memory-leak. It 
   has become a myth and nobody can explain it. I don't find a bug-report 
   in both Sun's and Tomact's bug-databases.

  I found it once but I can't find it again.  I was pretty sure I entered 
  memory leak in the summary field and came up with results, but it 
  doesn't work now.

  Anyhow, the javac bug is referenced in the release notes of 4.0.x.  I 
  don't think it's a javac bug but a tomcat bug with the interface into 
  the javac classes.  After all, it's not referenced in the release notes 
  for the newer versions of tomcat.

CacheFixedWaitTimeout: ??

Re: html not working

2003-12-01 Thread Graham Reeds

 As of my knowledge, I think Tomcat uses the concept of WebContext, which
 initialized during tomcat startup or through the manager commands,
 i.e. http://localhost:8080/manager/list
 check the documentations for manager commands on the tomcat website. where
 you can start/stop/restart webcontexts.. without the need of restarting
 tomcat.

Can that work on remote servers - ie:
http://www.mysite.com:8080/manager/list ?

I have tried repeatedly this weekend to get my web.xml to accept my new
welcome file (index.jsp) but it would not accept the changes.  I fired off
an email to my webhost, but I don't expect an email until I get home
tonight.

JNDIRealm question

2003-12-01 Thread Chong Yu Meng

Hi All,

I have a configuration that is not covered in the JNDIRealm HOWTO, and 
was wondering if someone else has tried this before :

I am using OpenLDAP 2.1.22 on Red Hat 9. For the DN, I am using the CN 
instead of the UID (i.e., dn: cn=Zhu De,ou=People,o=Cymulacrum instead 
of uid=zhude,ou=People,o=Cymulacrum), and the roles recognized by Tomcat 
are in the Groups OU.

My question : how do I setup a Tomcat JNDI Realm such that it looks up 
roles based on the UID instead of the DN ? In the JNDIRealm HOWTO, the 
instructions assume that the DN is using the UID instead of the CN. For 
the userSearch, I would substitute with (uid={0}), since I need to do a 
search and comparison with an attribute. But to retrieve the role ... 
I'm not so sure about how to do this. I'm thinking that the stanza below 
would not work (no, I haven't tried it yet). Does anyone know how it 
should look ?

Realm   className=org.apache.catalina.realm.JNDIRealm debug=99
connectionURL=ldap://localhost:389;
 userBase=ou=people,o=Cymulacrum
   userSearch=(uid={0})
 userRoleName=memberOf
 roleBase=ou=groups,o=Cymulacrum
 roleName=cn
   roleSearch=(uniqueMember={0})
/
Using the CN instead of the UID for the DN is actually (in my experience 
anyway) quite common -- Lotus Domino/Notes uses the CN for logging in, 
and Novell eDirectory too (though I suppose both can be configured to 
use the UID instead).

Thanks in advance,

pascal chong

Tomcat 4 vs Tomcat 5 and MIME settings

2003-12-01 Thread Stephen Thomas

Hi,

I must apologise, I've never used these types of systems before and have
sent this email to a couple of addresses. 

I am a developer of Voice applications. I use the Tomcat servlet engine to
host my applications which are then fetched from the voice server. I am
currently having an issue with Tomcat 5 and 'content-type'. The voice server
can play .vox files and I fetch such a file from Tomcat 5 and get the
following header:

lwp-request -d -e http://10.100.1.113:8080/test/soxTest1.vox
Connection: close
Date: Mon, 01 Dec 2003 09:30:03 GMT
Server: Apache-Coyote/1.1
Content-Length: 8130
Content-Type: audio/x-vox;charset=ISO-8859-1
ETag: W/8130-1069965466970
Last-Modified: Thu, 27 Nov 2003 20:37:46 GMT
Client-Date: Mon, 01 Dec 2003 09:29:38 GMT
Client-Peer: 10.100.1.113:8080

I have added the following lines to web.xml
mime-mapping
extensionvox/extension
mime-typeaudio/x-vox/mime-type
/mime-mapping

The file fails to play because of the charset being appended to the
'content-type'. When I host the application and .vox file on Tomcat 4 I can
play the file as the content-type is returned as only 'audio/x-vox'.

Please could you help me as I'd rather use Tomcat 5 but this issue is
currently stopping me.

Thanks in advance,

Steve

Tomcat 4 threads

I have some doubts about Tomcat and his threads. If someone could help me, i will be 
very grateful.

In what moment new threads are created in Tomcat when it's running? 
Is there a thread pool? In case positive:
- What is the initial quantity of threads created? 
- What is the stagger algorithm?
- After created, when a thread terminates (end of life, release)?
- What means o large number of threads? Many users? Many sessions? Many requests?

Re: Tomcat 4 threads

2003-12-01 Thread Andoni

Hello,

You should not have to worry about when tomcat creates or pools threads.

It will do this in the background in whatever way it does and you should not
have to know about it.

There are rules for keeping servlets thread-safe so that you will not be
affected by the threading of servlets by the container.  You can read about
how to keep your servlets thread-safe in the servlet specification which you
can download from here:

http://java.sun.com/products/servlet/download.html

Re: How to install new version of application (war file)

2003-12-01 Thread Jacob Kjome

The manager app in Tomcat5 now allows for a tag to be associated with the 
war you deploy.  You can use this from the ant manager tasks as well.  You 
can deploy an app and deploy the same app (different version) again with a 
different tag.  The old one will be undeployed and the new one will go 
in.  If you want to switch back, just specify the tag of an existing 
deployed version.

RE: endorsed directory

2003-12-01 Thread Philip Busby

Hi Basu,

I'm new to tomcat, and over the last weekend I've been poking and prodding
at Tomcat (with many problems, although none there wasn't a manual for).

As far as I can reason, xalan.jar is placed in the endorsed folder and not
the lib folder because it is endorsed by Tomcat... But they (we) didn't
write it. I figure there may be a more recent copy of the library elsewhere,
and if this is the case, you could put all of your lib directories before
your endorsed directories in your path, so the system will use the
first-hand libraries first.

Please correct me if any of this is wrong, playing with tomcat right now
feels like I'm fumbling with a bra clasp.

Nt Service and Sax Parser

2003-12-01 Thread Altug B. Altintas

Hi,

I have got very strange problem.  Here is the problem

If i write a bat file to start Tomcat like this


set TOMCAT_HOME=C:\tomcat
set JAVA_HOME=C:\j2sdk1.4.1
set RTDIR=c:\rt
set PATH=%RTDIR%\bin;c:\tomcat\;c:\tomcat\bin;.
set CATALINA_OPTS=-Xmx1024m
set CATALINA_HOME=C:\tomcat
set CATALINA_BASE=C:\tomcat
set CLASSPATH=C:\tomcat;.
cd %RTDIR%

call %TOMCAT_HOME%\bin\shutdown.bat
call %TOMCAT_HOME%\bin\startup.bat


Tomcat starts and my application works well. In my application i used SAX
parser APIs so i put crimson.jar and jaxp.jar to
TOMCAT_HOME\common\endorsed

Anyway this is not problem, the problem is when i want to make  Tomcat NT
service, my JSP pages which are uses  SAX Parser API doesn't work.

Here is the comments which i tried to make NT Service

**
set TOMCAT_HOME=C:\tomcat
set JAVA_HOME=C:\j2sdk1.4.1
set RTDIR=c:\rt
set PATH=%RTDIR%\bin;C:\tomcat;C:\tomcat;.
set CATALINA_OPTS=-Xmx1024m
set CATALINA_HOME=C:\tomcat
set CATALINA_BASE=C:\tomcat
set CLASSPATH=C:\tomcat;.



%CATALINA_HOME%\bin\tomcat.exe  -install tomcat
%JAVA_HOME%\jre\bin\server\jvm.dll -Djava.class.path=%CATALINA_HOME%\comm

My code is same, crimson.jar and jaxp.jar files are same, the difference

Has somebody already used mod_gzip with Apache  Tomcat ?

new verion of Tomcat Service Manager

2003-12-01 Thread David Boyer

version 2.0.8 is out.
 
-Changed GUI to multi-tabbed panels due the space constraints of a
single-paned form, and to work better with screen resolutions less than
1024 x 768. This should also make it easier to add options without
trying to pack everything onto the same form. 

-Added service start type parameter (disabled, manual, automatic). 

-Now using Windows API (advapi32.dll) for service control and status.
This should eliminate the dependency on WMI (better NT 4
compatibility).

-Using Timer component to automatically refresh the service status
every 5 seconds.

Windows Serive Permissions?

2003-12-01 Thread Karl Coleman

I have a command-line utility I am running that converts files into PDF. Here is the 
line we're using to run the program:

Process proc = Runtime.getRuntime().exec(cmd.exe /c C:\\BatchPDF.exe 
+rtfFile.getAbsolutePath()+ +pdfFile.getAbsolutePath());

The problem is, it only runs if Tomcat was started from the startup.bat file. If 
Tomcat is running as a service, which is how we want it, it does not run. We set up 
Tomcat to run under administrator with no luck. We are guessing this is a file 
permissions problem, either from running it as a Windows service or with Tomcat 
itself. Any ideas would be appreciated.

Thanks,
Karl

SessionListener

My SessionListener doesn't seem to be firing, any help?

I have a SessionListener that I want to go off when a user authenticates to my web app 
(this is a correct usage, right?)

So, in the web.xml of my app, I would put the lines:

web-app
listener
listener-class
the class
/listener-class
/listener
/web-app

This should fire off when the user signs in to the page, correct?

forward thing: tomcat 4.1

2003-12-01 Thread Kumar, Sumit

Hello,

This is more like a jsp question rather then the tomcat one but pardon me
for asking here. In my servlet, I do a 
getServletContext().getRequestDispatcher(
/reports.jsp?msg='selectEval'pid= + pid).forward( req, res ). The code is
given below. I believe this should forward it to reports.jsp[line (4)]. But
what happens is that even though it forwards it to reports.jsp, it continues
to execute the servlet even below the forward statement. When it encounters
the next forward statement[line (5)], it gives IllegalStateException. I
would think it should not go even past first forward[line (4)]. Please help
in clarifying.

if (revList.length  1)
{
req.setAttribute(revList, revList);   
   (4)getServletContext().getRequestDispatcher(
/reports.jsp?msg='selectEval'pid= + pid).forward( req, res );
}
else if (revList.length == 1)
{   

req.setAttribute(projEvalInfo, pe);
}   
(5)getServletContext().getRequestDispatcher(
/OtaceEvalFormRpt.jsp).forward( req, res );

Sun One Studio is Sun's 'extension' to NetBeans
Studio v4 was free, but v5 is not.
from Sun:-
Developers who prefer to continue using a free IDE and only require 
J2SE and Web application development capabilities should download the 
NetBeans http://www.netbeans.org open source IDE.

PS. If you have some space bucks, i'd go for IntelliJ's IDEA (or at 
least give it a spin)
They were good to us for a few licences(cheaper than what was stated on 
their site), and I believe they also offer educational discounts :)

Otherwise, NetBeans all the way, its bearable for free. ;)

Have you tried removing the connector line from server.xml?

then tried going direct to Tomcat on the port 8080 or whatever it is set to
in the Tomcat Connector on your machine (in server.xml)

This is a JK problem so try to remove it from the Equation and make sure the
rest works.

what did you change or what changed before this started happening?

You can get a mod_gzip module and do it from Apache which would 
probably be faster.

 Are you sure ?
 Has somebody already used mod_gzip with Apache  Tomcat ?

 I use it with Resin, but it was not possible with tomcat because 
 mod_jk replied directly to the client (so I think ...). There was many

 message on newsgroups about this. We had to adapt the sample gzip 
 filter provided with tomcat.

Listening to Session Creation... Need Access to Session

Ok, here's what I've tried.

1)  Implement SessionListener, put in web.xml file in listener tags.
This never seems to run.
2)  Implement HttpSessionListener, put in web.xml file in listener tags.
This runs, but doesn't seem to have access to the Session (I need the username 
and pass off the Session to authenticate to a database).
3)  Implement a Valve to do the same.
I saw that SingleSignOn uses a valve implementation, and is a SessionListener. 
 I see that it sets itself up to listen to its sessions, but now how this code is ever 
called!

So, my question is:
1)  Can I use SessionListener in any meaningful way?  Is there a way to add 
this to my xml files that I am unaware of?
2)  Can I get to the Session (or at least the data I need) from 
HttpSessionListener?
3)  Why isn't my valve running?  It's just valve className=theClass in my 
server.xml, right?

/mime-mapping

The file fails to play because of the charset being appended to the
'content-type'. When I host the application and .vox file on Tomcat 4 I can
play the file as the content-type is returned as only 'audio/x-vox'.

Please could you help me as I'd rather use Tomcat 5 but this issue is
currently stopping me.

Thanks in advance,

Does this mean it will still return a charset? I don't need any charset

Now, you won't get the charset unless you ask for it (so no more 
Content-Type: image/gif; charset=iso-8859-1
).  However, if you call response.setCharacterEncoding(iso-9959-1), 
you now get it in the response.

I will continue using Tomcat 4.1.27 until the fixed release of 5 is stable.
 

Will be released soon.

You are mostly correct.  The context will also be destroyed and a new

RE: Garbage Collection issues


Howdy,
Perhaps you are experiencing higher load, which requires more memory.
Or perhaps your application does have a memory leak: those are possible
and occur in java, so yes that would a programming error on your part.
The garbage collector does much magic, but it can't save you all the
time.  You may wish to read up on java memory leaks, as they've been
discussed at length on this list and on the net in general.

Note that when you call Runtime#gc that's only a suggestion to the JVM:
many times when you call that the garbage collector may not run at all.

My Tomcat 4.1 (hosted on Linux) seems to have a problem in recent
months
with crashing due to unavailable free RAM.  Specifically I get a
java.error.outOfMemory exception.  If check the RAM available
(Runtime.getRuntime().totalMemory()), I can see it ticking down through
the week.  If explicitly run garbage collection however my RAM totally
frees up and all is well (Runtime.getRuntime().gc();).

Why would this happen?  Surely this isn't due to a programming error on

whenever
the JRE performs periodic garbage collection. Isn't that correct?
Anyone have any theories as to what this may mean and what the best

RE: How can we know Tomcat is running or not through Standalone Java Prog


Howdy,
You have options that check slightly different things:
- Ping tomcat's port: checks the server is up, accepting request on the
port you check
- Specify a CATALINA_PID file, have your standalone program check for
presence of this file
- Write out your own file from your webapp, have your standalone program
check for presence of this file.
- Use a tool like Nagios

etc. etc.  This is a basic operational question.

I'd like to know why so few people bother to do a bit of research prior

You can search the archives of this list, and you'll see that you have
two main choices, summarized as:
- Put it under your webapp root, and use ServletContext#getResource(...)
- Put it on the classpath, and use ClassLoader#getResource(...)

- You have other choices, but they're more complex, e.g. JNDI
env-entry-refs
- You should NOT use a File-based approach, as it won't work in a packed

- Since these are connection properties for a DB, you may wish to let

A SessionListener of the org.apache.catalina variety would go in the

$CATALINA_HOME/conf/server.xml.  That means the class specified there

 I try to create many session (with a stress tool like grinder) and
i've
set
 session life time to 1 minute.
 Tomcat memory occupation stretch to increase ... inexplicably, in my
 opinion.
 When destroy session event occurs memory does not recycle...

 Thanks for help

RE: Tomcat 4 threads


Howdy,

In what moment new threads are created in Tomcat when it's running?

Under many possible circumstances: new webapp deployed, new request
arrived and current # processors on the receiving connector less than
max and all processors busy, some new JNDI resources (e.g. 3rd party
datasource reaper thread), some app code (e.g. log4j's configureAndWatch
call), many many.

Is there a thread pool? In case positive:

For some things, notably request processors, there's a pool.

- What is the initial quantity of threads created?

You specify it, see server.xml.

- What is the stagger algorithm?

You didn't really mean to ask that in this context, did you?

- After created, when a thread terminates (end of life, release)?

For request processors in current coyote, answer is when the server
dies.  But again there are many possible permutations.

- What means o large number of threads? Many users? Many sessions? Many
requests?

Any and all of the above as well as none of the above.  Consider for
example a server configured with ten connectors, each with 100 min spare
processors, one webapp per connector calling log4j's configureAndWatch
- 10*100 + 10 = 1010 threads.  And that's just on startup, before
receiving any requests or creating any sessions ;)

Howdy,
I'd like to know why so few people bother to do a bit of research prior
to posting ;(

You can search the archives of this list, and you'll see that you have
two main choices, summarized as:
- Put it under your webapp root, and use ServletContext#getResource(...)
- Put it on the classpath, and use ClassLoader#getResource(...)

- You have other choices, but they're more complex, e.g. JNDI
env-entry-refs
- You should NOT use a File-based approach, as it won't work in a packed
WAR distribution

- Since these are connection properties for a DB, you may wish to let
tomcat setup your datasource for you: see the JNDI DataSources How-To
document.

Howdy,
A SessionListener of the org.apache.catalina variety would go in the
same place as all tomcat-specific features:
$CATALINA_HOME/conf/server.xml.  That means the class specified there
must be accessible to the server classloaders, i.e. must reside in
common/lib or higher on the classloader hierarchy.

The above is true for Valves, Realms, Listeners, etc, that are
proprietary to tomcat.

RE: SessionListener


Howdy,

Ok, still, I haven't found any documentation on how to add a
SessionListener in the server.xml file, and adding one using the
listener
tags defined for web.xml files doesn't seem to work.

The XML is the similar but not quite the same to the portable one:
listener className=mypackage.myclass ... /  There is a generic
example in the Engine configuration reference, and another more specific
example in the Host configuration reference.  Neither, however, is a
SessionListener example.

There IS one specific, full-features SessionListener example: the
SingleSignOn valve.  It's present (but commented out) in server.xml by
default, and you can take a look at the source code.  It's a more
complicated and confusing example because it's also a Valve ;(  But then
again, I wouldn't even bother with this whole approach when you have the
HttpSessionListener as part of the servlet specification.

where ... are attributes specific to your listener.  (The astute reader
would recognize the above as a commons Digester bean-based
initialization pattern).

I also haven't seen how to get a user's credentials from a HttpSession,
or
how to get a Session from an HttpSessionListener.  Could you throw me a
bone?

If the user is authenticated by the server, typically the information is
not in the session, it's in the request:
HttpServletRequest#getUserPrincipal.  A common use-case is to stuff this
in the session via a filter.

If you had an attribute called username that something was stuffing into
the session, i.e. something like a filter calling
session.setAttribute(username, something), then an
HttpSessionAttributeListener's attributeAdded would be called with the
attribute name and latest value.

Re: forward thing: tomcat 4.1

Kumar,

Why not? There is nothing in the code to stop it from proceeding. Think in
the terms of a servlet. If you called a servlet instead of placing this code
in the jsp, how would you write it. Also do you mean for the (5) statement
to be outside your else bracket? Or did you mean for it to look like this:

if (revList.length  1)
{
req.setAttribute(revList, revList);
   (4)getServletContext().getRequestDispatcher(
/reports.jsp?msg='selectEval'pid= + pid).forward( req, res );
}
else if (revList.length == 1)
{
req.setAttribute(projEvalInfo, pe);

RE: Strange GET error with recent linux upgrade.

2003-12-01 Thread Brian Menke

I didn't get a response on this, but I did solve the problem and thought I
would pass it on just in case someone else runs into something similar.

I found out that the web.xml file was an older version that used an older
DTD (2.2). It was tied to an older version of tomcat. I think around tomcat
2.something. 

When they upgraded to the latest red hat enterprise linux, they were using
tomcat 4.1.29. The 2.3 DTD that is used by 4.1.29 includes the
servlet-mapping/servlet-mapping tags that let you specify the
url-pattern for your servlets. As soon as I upgraded the web.xml file to the
new version, and included the servlet-mapping, everything worked perfectly. 

I still don't understand why I got the original error message:

HTTP Status 405 - HTTP method GET is not supported by this URL

I would have expected a servlet not available message if tomcat couldn't
find it because the web.xml file was wrong?

Hi Everyone,

I have a client that just upgraded their Linux to the latest redhat
enterprise linux. They had a bunch of servlets that all worked with the
previous version just fine. Those servlets handled both post and get
request. After the update, all the servlets now display the following
message:

HTTP Status 405 - HTTP method GET is not supported by this URL

I think they just used what ever versions of java, tomcat etc. that came
with linux. I'm not real familiar with linux, or if this is even a linux
problem. Just wonder if there is something obvious that may have caused this
that someone may be aware of? Any insight is greatly appreciated.

jk-1.2.5 not working

I have apache 2.0.48, tomcat 4.1.29, and jk-1.2.5 on the latest Mac OSX

apparently failing to find a match when attempting to map the requested

I configured server.xml, workers.properties, and httpd.conf according 
to the instructions on John Turner's site 
http://www.johnturner.com/howto/apache2-tomcat4127-jk-rh9-howto.html. 
 http://localhost:8080/examples works, but 
http://localhost/examples returns:
	Not Found
	The requested URL /examples/ was not found on this server.
and /usr/local/jakarta-tomcat-4.1.29/logs/mod_jk.log has these lines 
(I've got JkLogLevel set to debug):

As far as I can tell, auto/mod_jk.conf looks right (it's about that

   server just to reload a webapp.
  
  
   Bugs have been filed for this issue against 4.1.x and they have been
   marked as WONTFIX.  Best to try to reproduce the problem on 5.0.x and
   if the bug still exists there, file a report in bugzilla if one does
   not already exist.
  
  
   Where can I find this information?  Is there a bugzilla for tomcat or
   something?  If so, I would like to go there so I can see if there's
   any information indicating where in the code it would be.  I could go
   searching myself, but I've never dove into the Tomcat code before! :)
  
  
   Could you post the bugid or even a link to the bug-report? i'm also
   interested in the porblem.
  
   I would also be interested in a description of the javac-memory-leak.
It
   has become a myth and nobody can explain it. I don't find a bug-
report
   in both Sun's and Tomact's bug-databases.

  I found it once but I can't find it again.  I was pretty sure I entered
  memory leak in the summary field and came up with results, but it
  doesn't work now.

  Anyhow, the javac bug is referenced in the release notes of 4.0.x.  I
  don't think it's a javac bug but a tomcat bug with the interface into
  the javac classes.  After all, it's not referenced in the release notes
  for the newer versions of tomcat.

If this can be done with HttpSessionListener, than I am game.

What I want to do, is get the username and password when the user signs on, so I can 
then use this data to authenticate the user to other programs as themselves.

I'm using BASIC authentication, and trying to avoid having them sign on a second time,

Sticky sessions - How to configure Apache?

2003-12-01 Thread Antonio Fiol Bonnín

Hello,

I have TWO Apache and THREE Tomcat servers. I tried to configure them to 
use mod_jk and sticky sessions.

Namely, I simply added jvmRoute=something to every server. A different 
something for each, as explained on the docs. I see it at the end of 
JSESSIONID cookie, so I must believe it is working.

However, sessions do not seem to be sticky. I am quite puzzled. Does 
one have to configure something on the Apacle workers.properties? I have 
not found anything...

Thank you very much.

Tomcat FAQs on Wiki

2003-12-01 Thread Mark Eggers

Folks,

I have put some of my documentation on the Tomcat Wiki
at:

http://nagoya.apache.org/wiki/apachewiki.cgi?TomcatWeb

These are sort of bare-bones documents about some ways
to connect Tomcat/Apache on Linux, Tomcat/Apache on
Windows/2000, and Tomcat/IIS 5 on Windows/2000.

Hopefully this will be of some use.

Re: SessionListener

2003-12-01 Thread Atreya Basu

Hi,

Here is how I use the HttpSessionListener.

First I create a Class that implements HttpSessionListener:
package com.gri.web;
import javax.servlet.http.*;
public MySessionListener implements HttpSessionListener
{
  private static int num_sessions = 0;
  private HttpSession session = null;
  public void sessionCreated(HttpSessionEvent se)
   {
   num_sessions++;
   session = se.getSession();
   }
   public void sessionDestroyed(HttpSessionEvent se)
   { num_session--;}
   public static int getNumSessions() {return num_sessions; }
public static HttpSession getLastSession() { return session;}
}
Now include this in the web.xml for your context (directly after 
filterfilter-mapping but before Servlet element):

|listener|
|||  listener-classcom.gri.web.MySessionListener/listener-class
/listener||
now all you have to do is create a JSP:
jsp:root xmlns:jsp=http://java.sun.com/JSP/Page;
jsp:directive.page import=com.gri.web.* /
jsp:text
html
body
|Last user in session:
/jsp:text
jsp:expression
MySessionListener.getLastSession().getAttribute(j_username)
/jsp:expression
|jsp:text
|Username of current person
/jsp:text
jsp:expression
session.getAttribute(j_username)
/jsp:expression
|/jsp:root
|/body
/html
/jsp:root

Howdy,
A SessionListener of the org.apache.catalina variety would go in the
same place as all tomcat-specific features:
$CATALINA_HOME/conf/server.xml.  That means the class specified there
must be accessible to the server classloaders, i.e. must reside in
common/lib or higher on the classloader hierarchy.
The above is true for Valves, Realms, Listeners, etc, that are

To solve the problem you have to add a new task defintion:

and replace the deploy task within the install target with the new above

That's it. 

Afterwards ant install will be successful

Re: How to install new version of application (war file)

Sorry Jake, I do not understand your suggestion.
In my manager/html there is no tag field in the deployment form.

 
Jeanfrancois link to the 5.0 documentation gave me the hint to 
put the autoDeploy=true to the server.xml :
  Host appBase=webapps name=myhost.mydomain autoDeploy=true
 ^

So now, when I copy my app.war to $CATALINA_HOME/webapps tomcat removes the 
corresponding directory app and redeploys the new app.war.

 in.  If you want to switch back, just specify the tag of an existing

RE: Garbage Collection issues

2003-12-01 Thread neal cabage

When I said that surely it can't be a memory leak in my app I was operating under 
the assumption that the JRE runs garbage collection periodically anywayis this not 
true?
 
If I was waisting resources and not releasing them in a way that the GC could take 
them back when it runs automatically then why would it take them back when I call 
garbage collection explicitly?  To me, this suggested more of a systemic issue.  It 
was suggested by someone last night that I may want to look at some config lines to 
make sure GC is active and this seemed in line with my assumption.  Is there something 
else here that I may be missing however?  Can you see a possible explanation as to why 
my app's waisted resources would not get cleaned up until I explicitly ran GC?
 
Thanks.

Perhaps you are experiencing higher load, which requires more memory.
Or perhaps your application does have a memory leak: those are possible

The garbage collector does much magic, but it can't save you all the

discussed at length on this list and on the net in general.

Note that when you call Runtime#gc that's only a suggestion to the JVM:
many times when you call that the garbage collector may not run at all.

Subject: Garbage Collection issues

My Tomcat 4.1 (hosted on Linux) seems to have a problem in recent
months
with crashing due to unavailable free RAM. Specifically I get a
java.error.outOfMemory exception. If check the RAM available
(Runtime.getRuntime().totalMemory()), I can see it ticking down through
the week. If explicitly run garbage collection however my RAM totally
frees up and all is well (Runtime.getRuntime().gc();).

Why would this happen? Surely this isn't due to a programming error on
my part, otherwise, the resources should automatically released
whenever
the JRE performs periodic garbage collection. Isn't that correct?
Anyone have any theories as to what this may mean and what the best
solution would be?

Thanks.
Neal

Tag Handler pool eating up Memory (and enablePooling is set to false)

2003-12-01 Thread Neil Aggarwal

Hello:

We have several tomcat servers running an application.  The servers
slow down after a few hours of uptime.

Looking at the memory usage on the servers, we noticed that the servers
seem to be accumulating memory and finally they slow down when
the memory utilization becomes high.

We are using the IBM JDK 1.4.1 SR1 with Tomcat 4.1.24 on RedHat 9.

Using the heapdump utility from the IBM JDK, I generated a heap dump
from one of the servers after it had been up for a while.

From that output, I see these pieces of infromation:

There were a total of 509,235 objects in memory 
taking up 67,992,688 bytes.

There were 436 instances of org/apache/jasper/runtime/TagHandlerPool.
Tracing all of the references from these TagHandlerPool object,
they reference a total of 65,010,600 bytes.

This means that almost 97% of the memory usage of Tomcat is being 
referenced from the TagHandlerPool objects.

I have enablePooling set to false in the Tomcat's web.xml in the conf 
directory.

It seems that the enablePooling setting is not preventing Tomcat from
pooling the tag handlers and they are referencing a lot of memory.

Does that setting work in Tomcat 4.1.24?

Is there any other reason why Tomcat would behave this way?

Thanks,
Neil

Servlet as Welcome File doesn't work

2003-12-01 Thread SH Solutions

Hello.

I'm using tomcat 4.1.29 on debian and I have the following problem:
I need to get / handled by my Servlet myPackage.Root, but I do not want
to change the mapping of ordinary files.
Just as a welcome file would, but welcome-file does not apply to servlets,
right?

My solutions so far is to map / to my servlet an map any other folder with
distinct context's, what surely is'nt what it was meant to be.

I did search the web and the usenet for a long time, since I assumed not to
be the first to run into this problem. But I didn't find anything.
Be aware that I did not enable the jsp-servlet, since I am not using jsps at
all.

If anyone can help me, I would appreciate it very much.

Thanks,

Steffen

Re: building mod_jk - exportable?

2003-12-01 Thread Christopher Schultz

Jon,

 Is it possible to modify the
settings for mod_jk *after* building it so I can export it to this
server from an internal build machine?
I don't think that mod_jk keeps any settings compiled-in, so you should 
be okay. Just to be extra-sure, you should compile it on a machine which 
is configured identically to your prod server.

Re: Servlet as Welcome File doesn't work

edit the $CATALINA_HOME/ROOT/WEB-INF/web.xml if you want the root 
application to show an custom welcome-file

and put 
  welcome-file-list
welcome-filemyFile.jsp/welcome-file
  /welcome-file-list
to the web-app tag.


This works on my tomcat 5.0

RE: Argument Type Mismatch

I thought that there was something related to that, is it that it must implement 
LifeCycleListener  SessionListener, or is SessionListener just not happening?  How is 
it possible, if at all, to add my own SessionListener?

RE: Tag Handler pool eating up Memory (and enablePooling is set to false)

2003-12-01 Thread Filip Hanik

are you sure this is a tomcat reference holding on to it?
it could be one of your classes as well, you need to run it through a memory
profile in order to find out
