Hello,
we have an Web Start application using JBoss. The client application works fine with JBoss 4.2.3.GA but throws Exception using JBoss 6. We use a code sniplet to invoke a bean home interface:

try
        {
            writeLog("connectionStr:", connectionStr);
            writeLog("jndiName:", jndiName);
            
            EJBHome home = getHome(connectionStr, jndiName, homeClass);
            writeLog("Home", "ok");
            writeLog("Home", home.toString());
            Method createMethod = homeClass.getMethod("create", (Class[])null);
            writeLog("createMethod", "ok");
            writeLog("createdMethod ", createMethod.toString());
            
            Object bean = createMethod.invoke(home, (Object[])null);
            writeLog("bean", "ok");
            // sessionCache.put(jndiName, bean);
            return bean;
            // }
            // return sessionCache.get(jndiName);
        }
        catch (ILServiceLocatorException e)
        {
            writeLog("bean", e.getMessage());
            throw e;
        }
        catch (Exception ex)
        {
            writeLog("Exception type", ex.toString());
            PrintWriter pw = null;
            try 
            {
                pw = new PrintWriter(new FileWriter("c:\\test\\properties.txt", true));
                ex.printStackTrace(pw);
                pw.flush();
                pw.close();
            } 
            catch (IOException e) 
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            throw new ILServiceLocatorException(
                    getMessageString("ErrorCreateBusinessDelegate.001"), ex);
        }



As a result we will get:
--- JBoss 4.2.3.GA ---

We think it has something to do of changes on jboss-remoting.jar. 

How can we solve the problem?

Thank you for your help
Volker
