"at java.lang.Thread.run(Thread.java:595)" was the last thing in my
catalina.out file. I refreshed several times and nothing changed. Are
there log levels in tomcat? Should I try to find this and increase the
amount of info being logged?
Thanks.

From catalina.out, you can find the root cause for this error, It's usually
right below this error...

I'm using tomcat version 5.5.7 with jdk 1.5.0_04 on a linux system. One of
my apps is giving me the following error when I try to access it. From
catalina.out:

I'm pretty sure it's something with our code, because another version of
the
web app seems to run fine. The problem is that I can't figure out what
this
error message is telling me and where to start looking. What exactly does
this mean? What problem am I getting?
Thanks for any help.
