Hi List,
Just wondering, anyone from the list who is attending the Tomcat training?
I'm flying to Amsterdam tomorrow, in case somebody is in for some beers, just
let me know! :)
Cheers.

Hi list.
I've got an issue which I would like to share with you guys.
My webapp requires a user to login, which on his turn creates a session
for that user.
Now, when I browse my webapp the address bar shows the current URL with
a JSESSIONID. Let's say:

I realize my question may be very dependent on the environment,
requirements and scope, but I was wondering if you guys recommend the

Don't know if this will answer your question, but I see that the
following class is loaded:

I'm not the developer of this webapp, so I'm afraid I cannot answer that
question.

Hello List,
A colleague of mine is having an issue with his application deployed in
a Tomcat 5.5.27 (jdk1.5.0_15) on a Debian Linux.
The application makes a connection to service running on a WebLogic
server. Therefor, he needs to include the weblogic.jar library in his
application.
When redeplo
The sessions are saved inside
$CATALINA_HOME/work/catalina/localhost/APPNAME/sessions.ser
In case you deploy a new version of your application or make
modifications, I suppose Tomcat sees this as a new application and
removes your current APP work-dir, and thus it's sessions.ser file

The thing is, using JDK5, I don't see any Xerces threads anymore that

Thanks Chris,
I just bumped into a very nice plugin for Jconsole called "TopThread".
It's a linux top alike and shows the CPU usage of all threads.
This only confirms what I figured out before, there are two threads
taking up all CPU. See below for their stack trace:

I'm quite sure that one of the RUNNING threads of Tomcat 6 is the
problem, which will probably be related to the webservice.
But I'm puzzled with wath the problem might be.
Sorry for the long response, I tried to be as complete as possible.

Hi
I got a Tomcat cluster set up, which is working for most applications.
However, since I am experiencing some problems (See another thread of
mine "Deltamanager + Session beans: Do they like eachother?"), I reread
the Tomcat clustering documentation.
The following are a few things that are not
A bit of more information.
The session bean is implemented using

I haven't found any relationship between that class and
incompatibilities with Tomcat and/or the DeltaManager.

Hello everybody,
First of all, to avoid any misunderstandings, below problems relate to
applications that I did not write, neither do I exactly know the
implementation of them. Although, if required, I can ask the programmer
for more information.
That being said, the problem that I am seeing is t

I replaced the SimpleTcpReplicationManager by the DeltaManager and
everything works as expected.

Hi all,
I'm having two Tomcats which are placed in a cluster.
If I stop and start a context (instead of completely stopping/restarting
Tomcat), then I see the following error in catalina.out:

Hi.
A quick question:
My session timeout is set to 45 minutes, so after a while I get a lot of
open sessions, although they are not active.
Is it possible that my application is slower because of the amount of
open sessions?
How much memory does a session occupy?
Thanks in advance
Hi Alberto,
I think this is merely "try and error".
Maybe jconsole would help as suggested by other people today.
I personally have not used it before.
Cheers.

Hi All,
I experienced a problem with Tomcat where all applications where
inaccessible. (Tomcat just hung, no 404 errors where given or
something).
The only thing that I think could be related to the problem is listed
below.
Exception in thread "TP-Processor15" Exception in thread

I think that is not possible.
In production, the best option would be to use a database or LDAP
directory to store your accounts.
