This seems invalid to me, though (they can't use a base URL, and expect the CL to have a straight organization of the classes). I've switched to a different mechanism in 5.0 to avoid careless accesses to resources which are inside JARs, which cause resource leaks (and seem to be exactly what Eclips seems to like doing). You have to load CL resources through CL.getResource or CL.getResourceAsStream. As a workaround, I belive you could try extracting your classes to /WEB-INF/classes.

Hi Remy, What you say sounds reasonable to me as a user of the eclipse code, looks like the developers of eclipse emf did not think of the problems such an access method can cause. Unfortunately EMF is a base for other APIs like XSD ... However, I did add a workaround in the CL which makes your test case work, but which has a performance penalty on first access to a JAR. I think avoiding resource leak is more important. Thanks a lot !! I agree. Best regards, Jan

Hi Remy, sorry for not sending you a test case, there were some high priority tasks coming in which had to be served first. As it looks now I will be able to set up a test case within the next 2 days.
