I hate to spam, but I should include this too. I seem to get it more
often than the other stack trace. Don't know if it helps or not :(
java.lang.NoClassDefFoundError
at org.apache.ojb.odmg.OJB.(OJB.java:68)

Thanks Steve.
The NoClassDefFound doesn't refer to anything. Here's part of the
Tomcat Error Report:

You need to compile with j2ee.jar or the equivalent, but don't install
that jar (or servlet.jar or any of that ilk) with your servlet -
Tomcat provides its own equivalent at runtime. This is the way the
Servlet spec works: the container is supposed to provide the classes
in servlet.jar, and individual servlets or webapps cannot.
What class does the NoClassDefFound refer to?
