That looks like it's still trying to read directly from the URL during the request. Yes I'm sure I changed the index.jsp However, it probably is still reading the old version found in /usr/share/tomcat-6.0.18/work/Catalina/ This might also be the cause. Is there anyway to flush it or better yet make it where it has to compile a new version each time. I realize in most cases this would NOT be the case.

RE: Reloading Tomcat Server
one of 3 things that could possibly be causing this the response is too big the response is taking too long (timeout) you need to authenticate to the url I would use wget or curl to determine what the error is if you point us to the URL i can test it out here and then we can suggest an appropriate solution Martin __ Disclaimer and confidentiality note Everything in this e-mail and any attachments relates to the official business of Sender.
