Keith Cochran commented on EJBTHREE-698:
----------------------------------------
I am seeing this issue as well whereas I was not when I was using JBoss4.0.3SP1 / JDK 1.4.2_06.
I've now changed everything over to JBoss4.0.5GA / EJB3.0 RC9 - FD / JDK 1.5.0_09 (and JDK 1.6 for comparison). With the 1.5_09 JDK, several of my DTO classes cannot be found on returns from remote calls. With JDK1.6 it is java.lang.Object that can't be found. My client classpath hasn't changed since the time it was all working under 4.0.3 JBoss.
I have found these forum threads seemingly related to this issue:
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=89959
http://www.jboss.com/index.html?module=bb&op=viewtopic&t=82578
Following JIRA reports as resolved for returned object arrays:
http://jira.jboss.com/jira/browse/JBREM-450
Generally my stack is the same as was posted above depending on which class wasn't found.
