You can let the plain jars have the ClassPath entries to point to other plain jars. Infact the EJB jars too can have Classpath entries pointing to *plain jar* files. But just make sure the EJB jars do not point to other EJB jars through Classpath attribute in the MANIFEST.MF. The reason i asked you to remove all Classpath entries was to keep it simple :)

Yes, it will work without the need for ClassPath attribute in MANIFEST.MF.

The plain jars in the "lib" of the EAR are available to all components, including the jars in the WAR file, within that EAR. So it will work.

Yes, the EJBs (placed at the root of the EAR) too will be available to the WARs (and the jars within that WAR).

No, not needed.
