After a lot of fiddling he agreed that this was the solution, but there was a bug in Eclipse and the class files should be copying across. We were on a tight deadline and needed to get something working and found that the easiest thing to do was keep the projects separate and jar up the other project&#8217;s classes and copy them into the WEB_INF/lib. Not an ideal solution, but at least you can run it in the debugger, hot recompiles are a bit flaky but it does the job.</p> <p>So I think the relevant people have been alerted, but if anyone else has any suggestions on what the current work-around is then please, please, pretty please tell us how.

Your above instructions seem to be the right solution, however, when I publish (or even do “Clean…") none of my classes are ever copied out to the tomcat directory. (e.g. to directory .metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\MyWebApp\WEB-INF\classes)

I am using eclipse ganymede 3.4.1.

Any other tricks or configs I am missing?
