Currently, Tomcat 4 doesn't really do session

clustering / distributed session management
solution that should work beautifully in the
the scenario you describe below.
The way it works is that all tomcats in the
cluster are given the same

some time period. This would help limit the number of threads in your

The cost of this solution is in making/breaking multiple TCP connections
for each request, but the advantage is that you gain control over what
resources the server is using.

I think that this may have to do with the security policy not allowing you
to load classes or jars from 'other' directories.
Look in conf/catalina.policy or conf/tomcat.policy (depending on the version
of tomcat you are using).
You will probably need to add an entry that looks like this:

This has nothing to do with tomcat. It is standard unix behavior.
When a user logs out, all processes created by that user are killed.
Unix provides simple way to around this feature.
Simply type the following command:
nohup tomcat.sh run
In this case all 'console output produced by
JSP provides an easier way to do what you are attempting.
However, the 'hot' include mechanism, is very much like a
function call. the output from the included jsp/servlet simply
appears in the middle of your output stream. It does not replace
the entire page.

Another solution is to simply deploy the apache web-application into the
same context as your own. This means that you have to merge web.xml
files, but it's otherwise pretty straightforward.
This means that only your web-application will be able to respond to
SOAP requests, however.
Depending on the proxy server, there may be a configurable
time-out.
Your web-application should spit back the HTTP header and
the beginning of your HTML document before you start the query.
Make sure to flush the output stream.

You should not have to unzip your classes12.zip file. This file is, for

Looking at your error message, I'm willing to bet that the problem is
