[jboss-user] [JNDI/Naming/Network] - Why does JBoss4.0.5GA not compatible with JBoss4.2.1GA while

[Herculesx]

  I have an application EAR package that deployed in a JBoss4.0.5GA server, the EAR have lots of EJB2.1 style beans and a WAR. Now I need to call a remote EJB3 style bean in another JBoss4.2.1GA server. My JNDI configuration is:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
  | java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
  | java.naming.provider.url=10.100.x.x
  But when it invoke lookup(), cause exceptions:
javax.naming.CommunicationException [Root exception is java.io.InvalidClassException: org.jboss.remoting.InvokerLocator; local class incompatible: stream classdesc serialVersionUID = -4977622166779282521, local class serialVersionUID = -2909329895029296248]

  But when I use jbossall-client.jar in JBoss4.2.1GA to run a client program with the same code, it is nomal. I try to copy the jbossall-client.jar from JBoss4.2.1GA in my EAR directory, and make this jar in ejb jar class path, but the default ClassLoader doesn't load this jar. So I modified the jboss-app.xml, use HeirarchicalLoaderRepository3 to load local jar file first, as this:
<?xml version="1.0" encoding="UTF-8"?>
  | <jboss-app>
  |    <loader-repository loaderRepositoryClass='org.jboss.mx.loading.HeirarchicalLoaderRepository3'>
  |       sso:loader=sso.ear
  |       <loader-repository-config configParserClass='org.jboss.mx.loading.HeirarchicalLoaderRepository3ConfigParser'>
  |          java2ParentDelegaton=true
  |       </loader-repository-config>
  |    </loader-repository>
  | </jboss-app>
   Then the situation even get worse, the EJB2.1 beans deploy failed!

   So, is there any way to call Jboss 4.2.1GA EJB3 bean from a JBoss 4.0.5GA EAR application?
