Jboss4 to Jboss3 connection problem

[zajaczeq]

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

These versions have incompatible client jars/apis. The first versions that will have been tested for cross version interop will be 4.0.2 and 3.2.8.
