What makes you think so? The doPrivileged() calls and SecureC
Odd,
I did not explicitly enable the security manager, but this makes sense. I
try logging directly from my servlet (by doing a stack trace into a log
file), which seems to be causing this issue.
thanks!

Oh... and I see it looks like you have the JVM's security manager turned
on. Have you made any adjustments to conf/catalina.policy? What's in
your logs when your webapp is started?

I really doubt the database pooling is causing the issue. More likely
your deployment is doing something to remove the servlet-api.jar or
duplicating it somewhere. What do you have in tomcat's lib directory
and in your webapp's WEB-INF/lib directory?

Hello,
I am trying to configure DB pooling in Tomcat 6. The combination of the
elements below causes the exception:
java.lang.ClassNotFoundException: javax.servlet.http.HttpServlet
I have followed the directions on

So the problem you see once a week occurs only when you start Tomcat?

First question: why are you putting a webapp jar in Tomcat's lib
directory? It belongs in the
well, but once a week or so we'll get a Class Not
Found exception in the Tomcat std out log -- Tomcat can't find this very
important class. The webapp will obviously not work, and once Tomcat is
restarted, normal functionality resumes.
I'm no Tomcat developer, so I'm struggling
