Debug Java actions in Eclipse: no files found

I'm getting this error when trying to start the debugger in Eclipse for my Java actions: Error: no files found in WEB-INF/model/ The project was deployed and there are indeed files in this directory; and it is not marked read-only or anything. Presumably something is pointing to the wrong place, anyone know how to sort it out please?

In the WEB-INF/model should only reside .class files, and Eclipse cannot do anything with them, since they are already compiled. Your Eclipse project should point at the javasource directory (not in WEB-INF), which should contain the source code (.java files) of those classes.
