Hi, I need to connect
to legacy jboss servers from our new jboss 3.0.6 servers. I can’t get
a remote reference to my EJB running on JBoss 2.4.4 from
code running inside jboss 3.0.6. I have made this work
between jboss 2.4.4 and jboss
3.0.4 – all I did was put the old 2.4.4 jboss-client.jar
into the 3.0.4 deploy directory (probably not such a good idea but it worked!). However if I
simply put the old jboss 2.4.4 jboss-client.jar
into my deploy directory with jboss 3.0.6 I get the
following error on the jndi lookup. javax.naming.CommunicationException. Root exception is java.rmi.ServerException: RemoteException
occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling
arguments; nested exception is: java.lang.ClassNotFoundException: org.jnp.interfaces.FastNamingProperties

accessing the EJB in jboss 2.4.4 directly using a
test console client and discovered it works with the older jboss-client.jar
at the beginning of my classpath: CLASSPATH=/home/work/nick/JBoss-2.4.4/client/jboss-client.jar:\ /home/nick/JBoss-2.4.4/client/jnp-client.jar:\ /home/nick/jboss-3.0.6/client/jboss-client.jar:\ /home/nick/jboss-3.0.6/client/jbosssx-client.jar:\ /home/nick/jboss-3.0.6/client/jnp-client.jar:\ /home/nick/jboss-3.0.6/client/jboss-j2ee.jar:\ /home/nick/jboss-3.0.6/client/jbossall-client.jar:\ … but when it’s at the end I get a
similar error. CLASSPATH=/home/nick/jboss-3.0.6/client/jboss-client.jar:\ /home/nick/jboss-3.0.6/client/jbosssx-client.jar:\ /home/nick/jboss-3.0.6/client/jnp-client.jar:\ /home/nick/jboss-3.0.6/client/jboss-j2ee.jar:\ /home/nick/jboss-3.0.6/client/jbossall-client.jar:\ … /home/work/nick/JBoss-2.4.4/client/jboss-client.jar:\ /home/nick/JBoss-2.4.4/client/jnp-client.jar:\ This
points
to class conflicts between the old 2.4.4 jboss-client
classes and the new 3.0.6 jboss-client classes. java.rmi.ServerException: RemoteException
occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling

(no security manag er: RMI class loader disabled) Does anybody know
the right way to do this? Cheers and
