1. Re: EJB3 Remote client problem
starksm64 Dec 31, 2005 5:04 PM (in response to ramanap)Its a bug in how the proxies are maintaining their serialVersionUIDs:
http://jira.jboss.com/jira/browse/EJBTHREE-402
You will need to have the same classes/jars on the client/server. The error indicates that you have mixed versions and are seeing the incompatibility bug. -

ramanap Jan 1, 2006 9:18 AM (in response to ramanap)I have copied the same jars from the server to the client. Still I get the error.
Thanks -
3. Re: EJB3 Remote client problem
starksm64 Jan 1, 2006 9:49 AM (in response to ramanap)You still have the out of date classes visible on the client then. Explicitly load the org.jboss.ejb3.stateless.StatelessRemoteProxy class and print out its codebase/serialVersionUID:
import java.io.ObjectStreamClass; ... ClassLoader tcl = Thread.currentThread().getContextClassLoader(); Class srp = tcl.loadClass("org.jboss.ejb3.stateless.StatelessRemoteProxy"); System.out.println(srp.getProtectionDomain().getCodeSource()); ObjectStreamClass osc = ObjectStreamClass.lookup(srp); System.out.println("getSerialVersionUID: "+osc.getSerialVersionUID());

ramanap Jan 1, 2006 2:25 PM (in response to ramanap)Yes, You are right. The problem was jars mismatch between client and server.

5. Re: EJB3 Remote client problem
ahachmann Dec 8, 2006 11:34 AM (in response to ramanap)Hello,
I am having a similar problem. But the Class that seems to be invalid is a different one. I have also copied the jars from the Server to the Client.
I am working with 2 JBoss Servern Version 4.0.4 GA. The one server is looking up a remote bean on the other.
How can i fix this ClassMissMatch when even copying the Jars does not heltp?
I am quiet frustrated with this problem.
Happy about every Help,
