[jboss-jira] [JBoss JIRA] Resolved: (JBAS-7807) EJB method having QName as an argument fails on jboss

EJB method having QName as an argument fails on jboss ------------------------------------------------------ Key: JBAS-7807 URL: https://jira.jboss.org/jira/browse/JBAS-7807 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: EJB3 Affects Versions: JBossAS-5.1.0.GA Environment: linux Reporter: Rishi Agarwal Assignee: Carlo de Wolf 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.
