User development, A new message was posted in the thread "[6.0.0M2] EJB Implementation Class for EJB XXX was not specified": http://community.jboss.org/message/528004#528004 Author : jaikiran pai Profile : http://community.jboss.org/people/jaikiran Message: -------------------------------------------------------------- I just tried this similar example against 6.0.0 M2 with a simple jar. Everything worked fine. Can you please provide more details about your .ear? Or can you attach the .ear or a trimmed down version of that .ear, which reproduces this issue, to this thread? Also does any of the jars or the ear have any Class-path entries in the MANIFEST.MF files? If yes, try removing those entries. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528004#528004
