java.lang.IllegalStateException
tomcat 3.2.1 redhat 7 every now and then, we get the following error. it seems to only happen when we are compiling new classes a lot during development. if we are not developing, but rather, just using our application, we never get this error. has anyone seen this before?

Re: tomcat startup problem
thanks all. ps awx | grep tom revealed a lingering process... strange.

Try typing 'ps awx' from the command line and looking for java processes. If java is running, first try stopping Tomcat again with the shutdown script. If that doesn't get rid of all your java processes, run 'killall java' from the command line -- assuming you don't have anything else important running java on your machine! I've had to do this a few times, if Tomcat doesn't shutdown properly on it's own.

changing web app
This may be a basic question, but I havent seen the answer in any of the docs - do I need to restart tomcat every time I change my web.xml config file for my web application? or is there someway to reload it? thanks
