I have a big problem. I am connecting from EJB located on Jboss 4.0.1SP1 to EJB 
located on Jboss 3.2.3. 
But when I invoke method context.lookup I am getting exception 
java.io.InvalidClassException. 
I know that problem is with objects serializaion and diferent versions of class 
org.jboss.util.id.GUID but I don't know solution. 
Does anyone know solution or work around for this problem?

Exception I get:
javax.naming.CommunicationException [Root exception is 
java.io.InvalidClassException: org.jboss.util.id.GUID; local class 
incompatible: stream classdesc serialVersionUID = 6926421946503004889, local 
class serialVersionUID = 3289509836244263

        at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:663)
        at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:520)
        at javax.naming.InitialContext.lookup(InitialContext.java:351)
...

Best Regards,
Michal
