--------------------------------------------------------------
Hello,

I'm trying to deploy a Stateless Session Bean with Bean-Managed Transaction on JBoss AS 6.1 with the default configuration.
Methods in that bean throws application exceptions, which are annotated with @ApplicationException.

When a method throws an application exception, it's wrapped in an EJBException.

If I use Container-Managed Transaction, application exceptions are not wrapped in EJBException.

The Stateless Session Bean  (I use a very simple case as an example, but the problem is the same) :

package org.helloworld;

import javax.ejb.Stateless;
import javax.ejb.TransactionManagement;
import javax.ejb.TransactionManagementType;
import org.helloworld.exception.MyAppException;

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class MyBean implements MyBeanRemote {

    public MyBean() { }

    @Override
    public void doSomething(boolean throwException) throws MyAppException {
        if (throwException) {
            throw new MyAppException("Oops") ;
        }
        else {
            return ;
        }
    }

}


The remote interface :

package org.helloworld;
import javax.ejb.Remote;

import org.helloworld.exception.MyAppException;

@Remote
public interface MyBeanRemote {

    public void doSomething(boolean throwException) throws MyAppException;

}


The application exception :


package org.helloworld.exception;

import javax.ejb.ApplicationException;

@ApplicationException
public class MyAppException extends Exception {

    private static final long serialVersionUID = 1L;

    public MyAppException() {
        super();
    }

    public MyAppException(String arg0, Throwable arg1) {
        super(arg0, arg1);
    }

    public MyAppException(String arg0) {
        super(arg0);
    }

    public MyAppException(Throwable arg0) {
        super(arg0);
    }    
}



The client program (java SE) :


package org.helloworld.client;

import javax.naming.InitialContext;

import org.helloworld.MyBeanRemote;
import org.helloworld.exception.MyAppException;

public class MyAppClient {

    public static void main(String[]  args){
        try {
            InitialContext ctxt = new InitialContext() ;
            MyBeanRemote myBean = (MyBeanRemote) ctxt.lookup("HelloworldEAR/MyBean/remote") ;
            myBean.doSomething(true) ;
        }
        catch (MyAppException e) {
            System.err.println("My App Exception Message : "+e.getMessage()) ;
        }
        catch(Exception e) {
            e.printStackTrace() ;
        }
    }
}



And here, the stacktrace, when I run the client code :
