Moving EJB jar from 4.2.2 to 6.x deployment exception

[borfnorton22]

We have a jar which works fine on 4.2.2, not on Jboss 6 when starting we get this

23:20:23,233 ERROR [AbstractKernelController] Error installing to Start: name=jboss-switchboard:appName=MyApp,module=MyApp,name=MyAppImpl state=Create: java.lang.ClassCastException: $Proxy255 cannot be cast to javax.naming.Context

In the MyApp.jar we have a class defined as

public @Stateless class MyAppImpl implements MyApplLocal, MyAppRemote

The @local and @Remote s are defined in the subsequent implemented interfaces above

[jaikiran]

Please post the exact code of that bean class and its interfaces. Also do you have any ejb-jar.xml or jboss.xml? If yes, please post the contents of those files too.

[borfnorton22]

There are no entires in ejb-jar.xml related to these classes, only annotations per the below

public @Stateless class MyAppImpl implements MyAppImplLocal, MyAppImplRemote
{
method implementations....

@Local
public interface MyAppImplLocal
{
method declarations....

@Remote
public interface MyAppImplRemote
{
method declarations....

Then there are 2 other beans in the same jar which reference the local interface such as

    @EJB
    private MyAppImplLocal myApp;

[jaikiran]

Without looking at the (complete) real code it's difficult to say what's wrong. Can you post the entire code of that bean? Or attach a simple application which reproduces this?

[borfnorton22]

I can't post the contents of the code/class

I think it has something to do with remote/local names? Seems related to this issue but I can't figure out why

https://issues.jboss.org/browse/EJBTHREE-1545

[jaikiran]

Even though the error message is same, the issue isn't the same. The issue you are running into has to do with some injection that's happening within the MyAppImpl bean implementation.

I can't post the contents of the code/class

Can you atleast post some dummy code which resembles that class (by removing application specific bean names or such things)? Without that, it's difficult to tell what's wrong.
