I put deleted in quotes because that is what my client is claiming. The users of the system were working this morning and getting error 500s when trying to access the jsp pages. The error log was stating that it couldn't find the jsp pages. They restarted Tomcat and everything was back to normal. They are claiming that no users other than people using the Tomcat, were doing anything in the system. So their conslusion is that Tomcat deleted the work directory. Is that at all possible? I know that if the work directory doesn't exist, the next time somebody restarts Tomcat, it will recreate it as well as compile any jsp pages that are run. But I've never seen Tomcat delete the work area while still running.
