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/528239#528239 Author : Guy Coleman Profile : http://community.jboss.org/people/gcoleman Message: -------------------------------------------------------------- Found it. There's a weblogic client jar included in the EAR (we need to access some Weblogic JMS queues), and if that jar is removed the ear deploys without any problems.   It also fixes the issue in my other thread http://community.jboss.org/message/527872   I sense some manual jar hacking coming up.. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528239#528239
