Error in Seam Action accessing another JBoss instance passin

I have a Seam application(the booking example in fact) invoking a request to another JBoss app server.
This app server returns the entity objects as result which triggers the exception below:

java.io.InvalidClassException: org.hibernate.collection.PersistentBag; local class incompatible: stream classdesc serialVersionUID = -992182677146982163, local class serialVersionUID = 2819117614876030537

Anybody know how to work around or avoid this problem?

Use the same Hibernate version on both.

finally found the solution.

earlier i just added the hibernate-entitymanager.jar, javaassist.jar to the class path of the entire application not individually and i was also not adding the hibernate3.jar.

now i included hibernate-entitymanager.jar, javaassist.jar and hibernate3.jar to the class path of both the client and ejb module separately.

then deleted all the old jar files, emptied the tmp folder, restarted the server, rebuilt all the packages, redeployed the application and executed the client. it worked fine!

thanks
