Re: ClassNotFound Exception with Struts Action
Hi Adam, Well the problem was basically a lot more trivial. I use JBuilder Enterprise to build my apps. It has a facility called 'Refactoring'. You can rename classes, packages etc. and it should rename all references of the object you rename. It does all the Java things but NOT the XML stuff. So I renamed my action class but the action mapping in the XML file containing the struts configuration was not changed! Thats why the class could not be found. Since I could still not figure out, how to configure JBuilder to write a log file when tomcat runs in its debugger, I just saw it, when running a deployed version.

To find out the classpath being used by your app server, you should put an echo in your app server's batch file at the appropriate point, i.e. just before it calls javac. However app servers generally don't include the webapp directories in the classpath that java uses. It should all be internal. A frequent error is the spelling. It's case-sensitive.
