I am interested in solving this problem as well - I have worked on this for the last 1.5 days, and searched the forums for a solution, but can't find any? Has anyone been able to get a REMOTE EJB3 client working with jboss? If so please explain the steps... If I include my jar file that has the EJBs in my client's classpath, I get class cast exceptions. If I dont' then I get rmi security exceptions ("no security manager: RMI class loader disabled") - If someone knows how to get past the security problem, that would be great to know.. Thanks!
