    Connection problems

      JBoss gurus,

      I just downloaded the JBoss 4.0.0 DR2 release a few days back and I was able to start the server, deploy my application without any problems.

      When I try to connect to the application from a remote client, I get the following error:

      java.rmi.RemoteException: Failure looking up home javax.naming.CommunicationException [Root exception is java.io.InvalidClassException: org.jboss.invocation.remoting.RemotingAdapter; unable to create instance]

      I have already had the jndi properties for the client to have the following:
      java.naming.provider.url=jnp://myhostname:1099 java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

      I also have on my server startup the following java startup parameter -Djava.rmi.server.hostname=myhostname

      I am not sure why I am seeing the above exceptions. Any ideas/suggestions?

          > java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

          Is this a typo?

          Under 3.2.1 I'm using the following:

            in jndi.properties it has the org.jboss.naming package in there for the class org.jboss.naming.HttpContextNaming Factory. That's used for using the JNDI over Http.

              We're finding similar problems with 4.0.0DR2. At the moment we're just trying to get a reference to a session bean from a remote (outside VM) client, but with no success so far.
              It appears that the default transport mechanism has been changed; after throwing various jars into our client config it's now busy creating an Axis server/taking over the world etc.
              It would be great if we could curtail such notions and simply get a reference to the session bean :) - do we need to modify our client jndi.properties file or must we reconfigure the JBoss server (the remoting service or similar)?
              Any help would be much appreciated: losing hair fast!
