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 =

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?
