Hi All,

I am having a client connection problem.  I am using JBoss 5.0 implementing JDK 6.  I have sucessfuly deployed my test Stateful bean and here is the output from the URL:http://localhost:8080/jmx-console/ (after selecting service=JNDIView from the jboss section AND pressing 'Invoke' from the list operation):

java: Namespace

  +- UserTransactionSessionFactory (proxy: $Proxy125 implements interface org.jboss.tm.usertx.interfaces.UserTransactionSessionFactory)
  +- TS_AppClient1
  |   +- UserTransaction[link -> UserTransaction]
  |   +- metaData
  |   +- env
  |   |   +- testserver
  |   |   |   +- HelloStatefulBean[link -> HelloStatefulBean]
  |   +- classPathEntries

Now when I use my standalone client, to access this Stateful bean, I continue to get the following stack trace:
Before silly 1:
javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out]

        ... 5 more

Here is the client code:

public class Main
    public static void main(String[] args)
        InitialContext ctx = null;
        HelloStatefulRemoteInterface silly;
        Object array[] = new Object[1];
        Properties prop = new Properties();

            prop.setProperty("j2ee.clientName", "TS_AppClient1");
            ctx = new InitialContext(prop);
            System.out.println("Before silly 1:"+ctx.getNameInNamespace());
            Context enc = (Context) ctx.lookup("HelloStatefulBean");
            System.out.println("Before silly 2:"+enc.getNameInNamespace());
        catch (NamingException e)

Also, my jndi.properties file has the following key/values:

Here is my jboss-client.xml:

I have tried doing the lookup with the text from the 'ejb-ref-name' with no success...

Anybody have any thoughts?
