Probably the exception happened because the PortableRemoteObject.narrow()
was not able to load an IIOP stub class. More info on this below.

The IOR:xx part looks good. The com.sun.corba.se.internal.iiop part means
that your client is not using JacORB. The client is using the Sun ORB
provided with, which is not able to dynamically download IIOP stubs.
More info on this below.

This looks good.

Right.

Right.

Right.

It looks that you are using jacorb.jar only at the server side.
The Sun ORB is being used at the client side.=20

OK.
In addition to these things you need to ensure that the client
finds the IIOP stubs it needs. Here you have two options:
1) Use JacORB at the client side and grant the client permissions
to download the IIOP stubs from the JBoss server.
2) Use the command 'rmic -iiop' to pre-generate the IIOP stub classes
and put these classes in the client classpath.
With option 2 you do not need to use jacorb.jar at the client side
(you may use the Sun ORB), but you need IIOP stub classes avaliable=20
at the client side.
Option 1 is the one I recommend. It does not require you to generate=20
IIOP in any way, but requires two changes to the run-client script.
- Change 1 is to specify that JacORB is to be used at the client side:
keep jacorb.jar in the client classpath (you already have it there)
and pass to java the switches=20
'-Dorg.omg.CORBA.ORBClass=3Dorg.jacorb.orb.ORB' and
'-Dorg.omg.CORBA.ORBSingletonClass=3Dorg.jacorb.orb.ORBSingleton'.
(An alternative -- and overkill -- way to accomplish the same thing
is to prepend jacorb.jar to the boot classpath, with a switch like
'-Xbootclasspath/p:C:\pack\java\jboss-3.0.1RC1\client\jacorb.jar'.)
- Change 2 is to grant the client rights to download IIOP stubs
from the JBoss server: pass to java the switches
'-Djava.security.manager' and
'-Djava.security.policy=3DC:\path\to\your\java.policy'
=20
The java.policy file should at least grant your client permission=20
to connect to the port 8083 of the JBoss server. To make things=20
work, it might be easier to start with a java.policy file that=20
grants AllPermission: =20
grant {
// Allow everything for now
permission java.security.AllPermission;
};
Change the run-client script as indicated above, and you may just forget=20
about IIOP stubs. You will never have to generate them.=20
If you use an IOR parser utility to inspect the IOR of your EJB, you=B4ll
see that it includes a Java codebase tag:
#1: TAG_JAVA_CODEBASE
Codebase: http://ukp10775:8083/WebCL[ejb/test/TestSession]/
Clients will automagically download IIOP stubs from the URL above.
Hope this helps. (I should have already added this info to the IIOP=20
page at the JBoss site.)=20
Best,
Francisco
