Proxy error

jactor Jul 23, 2005 7:12 AM

When I use the JNDI context to look up a bean thir error occurs:

Ex:
InitialContext ctx = new InitialContext();
container = (TeamContainer) ctx.lookup(TeamContainer.class.getName());

Error:
$Proxy136 (org.apache.jsp.team_jsp)
in org.apache.jsp.team_jsp.jspInit, line 28
in org.apache.jasper.runtime.HttpJspBase.init, line 78
in org.apache.jasper.servlet.JspServletWrapper.getServlet, line 145
in org.apache.jasper.servlet.JspServletWrapper.service, line 305
...

Any ideas? I use jboss-4.0.3RC1...

Regards!

Are you sure that is all of the error? doesn't the error start higher?

Have you packaged the beans interface in the web app as well as in the war file?

Are you sure you the error is a proxy error? Are you sure that it is not a ClassCastException?

If it is a class cast exception and you have packaged the interfaces in the war, remove the interfaces from the war.

Yes, I am sure this is the error...

The only thing that is changing is the proxy number (look at the errormessages I pasted earlier).

I get the same error if I have the interfaces in the war file and vice versa. Should I have the interfaces in the war?

...and you are right...

...it is a ClassCastException whith the errormessage given...

When I debugged the exceptiontype this class was what has been thrown...

Anyone who got an idea about what is causing this ClassCastException/proxy failure?

This is an annoying show-stopper, and I don't have a clue abaout what could be wrong. I thought I followed the EJBTrail examples thorough and I can't backtrace the failure... I can't see that what I have done is different from that... The only thing that I have done different from the example is using entity beans in generic collections. But if this is the problem, I thought it would bring me some different errormessage than a class cast exception with a proxy error...

Please... Anybody: help!

As darranl has already mentioned:

Remove the bean classes and their interfaces from the war file

... as I already said: I get the same error anyway.

At least now I know that they should not be there...

Any others idea?

I am working on several things on my server and things suddenly start woking, so I must have done something that has the right sideeffect.

Thanx for the tips anyway!

See http://www.jboss.com/index.html?module=bb&op=viewtopic&t=67287 for my solution. Instead of packaging an EAR, I got it all running out of eclipse using 2 source (and build) paths. This keeps the interfaces out of the web-inf/classes path.
