Icefaces and Tomcat Crash-Collection of common programming errors

I have an application made with ICEfaces and ran on Tomcat 6. When I try to access one of the pages where I select users, if gives me this error. The weird thing is, after I get the error, I refresh the page, and it normally goes to where ever I needed it to go to.

Does anyone know what the error actually means, because the lines of code that are highlighted are closing of a DB connection, a comment line (weird lol), and some other syntax stuff that can’t have errors in it.

exception

Has the NPE. Doesn’t look like IceFaces code at all, probably what you are building.
