java.lang.ClassCastException: org.jnp.interfaces.NamingConte

[toplink]

Hi,

I have an ejb2.0 sessionbean and ejb3.0 pojos, the sessionbean is defined in ejb-jar.xml along with persistence-context-ref and persistence-unit-ref.

In the client, it will look up the sessionbean by jndi look up "test-client/ejb/TestRunner" to create the sessionbean to operate entity. Now I have a problem in the jndi look up, "test-client" is the "display-name" in application-client.xml, "ejb/TestRunner" is the "ejb-ref-name" in application-client.xml, and I see "Global JNDI Namingspace" in jmx-console is:

+- test-client (class: org.jnp.interfaces.NamingContext)
| +- ejb (class: org.jnp.interfaces.NamingContext)
| | +- TestRunner[link -> TestRunnerBean] (class: javax.naming.LinkRef)

See the look up string is exactly matching the one displayed in Global JNDI Namingspace, but I got exception. I saw bunch of posts talking about the ClassCastException, but it seems none of them is related to my case, does anyone have idea about this?


Thanks.

in application-client.xml, "ejb/TestRunner" is the "ejb-ref-name"

Did you try looking up using

ctx.lookup("ejb/TestRunner");

I tried it already, if i look up like ctx.loopup("ejb/TestRunner"), I will get:

javax.naming.NameNotFoundException: ejb not bound

what's the exception you're getting?

The exception I got is:
