When starting up Tomcat, I would like to do a System.exit() if an exception
of any kind is thrown. Is there a way to configure this? We are using a
large number of frameworks (Spring, Hibernate, log4j) and I want the
developers to pay attention right away if there is something wrong and to

I agree that many have experienced the jsessionid on URLs accessed by bots,
perhaps it happens in a Struts environment or some other environment.
In certain set-ups (only JSPs, no servlets, no MVC - session is removed and
created freshly on each JSP page) the jsessionid doesn't appear on URLs

Not really. The generational HotSpot collector does reserve a port

We've seen errors where individual queries are improperly bounded or
unbounded allowing requests to attempt to retrieve unreasonable amounts of
data. A single request like this can take an otherwise stable system and
throw it into all sorts of bad behaviors and error conditions.

We have a fairly substantial amount of data that is loaded on startup and
remains for the duration. This probably accounts for part of the old-gen

Sharon,
You have quite a bit of memory in your 'Old Generation'. You need to

How many sessions do you have active when the problem occurs? What is your

Hi Huges,
The standard Tomcat 5.5 policy file includes:

permission java.security.AllPermission;
};
which grants permission to the common/endorsed jars.
It is possible for code to programmatically grant itself some
extra permissions, such

Has anyone gotten a custom ELResolver to work in Tomcat 6.0.x using the

It is likely that some other class in your webapp is on the
stack when the permission check occurs and it causing the
check to fail. You could try ".../WEB-INF/-" to expand
the grant to the entire webapp and see what happens.
To diagnose this kind of exception, you can add the following
