Carlo de Wolf resolved JBAS-7807.
---------------------------------

    Resolution: Rejected


Any class used as an argument (or return type) on an EJB method is considered to be an user / application class.
It's not up to the container to ensure that both client and server have the same version of those classes installed.

> I have a EJB method that has  javax.xml.namespace.QName as an argument. On trying to connect to it from the jse client it gives the following exception: Our EJBs are deplyed on JBOSS AS 5.
> java.lang.RuntimeException: java.io.InvalidClassException:  javax.xml.namespace.QName; local class incompatible: stream classdesc  serialVersionUID = -9120448754896609940, local class serialVersionUID  = -711357515002332258
> After removing QName class from stax-api.jar in the endorsed\lib directory , i could successfully invoke the EJB method. This is the due to the fact the QName class is available as part of JRE libraries as well and i guess this is a well-known fact that there are issue around it due to incompatible serialVersionUID.
>  
> Now my point is what is the solution to resolve this.We can't recommend removing QName class from stax-api.jar for EJBs( methods with QName as argument) to work.
