RE: embedded openjms server

It *should* work, although I haven't tried it with tcp.
 What version of OpenJMS are you using?

Note that if all calls to OpenJMS are in the one JVM,
then the tcp connector is overkill - you should use the
embedded connector instead:

Hi,

I would like to run JMS Server as a component in another Java Application(
in the same VM).  Here is what I did:

//configFile is the xml file for OpenJMS configuration.  I used tcp_jms.xml
in %OPENJMS_HOME%\config directory as the base
        EmbeddedJmsServer jmsServer = new EmbeddedJmsServer(configFile);


In my command console widnow I see TCP JNDI Server started as following:

15:46:30.290 INFO  [VSE Manager Server] - Started TCP JNDI Server on port
3035
.
.
After this line, I don't see any other printouts as what I see when I run
the startjms.bat located in OPENJMS_HOME%\bin directory.

15:53:36.798 INFO  [main] - Started TCP JNDI Server on port 3035
15:53:37.126 INFO  [main] - Started the JNDI service

15:53:37.485 INFO  [main] - Registering Garbage Collection every 120000 for
other resources.
15:53:37.501 INFO  [main] - Started service [GCCollectionService]
15:53:37.595 INFO  [main] - Started service [MessageManager]


 I believe that something is not quite right.  I also tried to write a
simple test program and try to create the initialContext as following.

----------------------------------------------------------------------------
----------------------------------------------------------------------------
--------

        Hashtable props = new Hashtable();
        String sHost = "localhost";
        String sPort = "3035";
        props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.exolab.jms.jndi.mipc.IpcJndiInitialContextFactory");
        String sURL = "tcp://" + sHost + ":" + sPort + "/";
        props.put(Context.PROVIDER_URL, sURL);
        try
        {
            Context context = new InitialContext(props);
        }
        catch(Exception e)
        {
        }


I got following exception.

javax.naming.CommunicationException: Failed to connect to JNDI service: Read

Can someone give me some idea, what I did wrong?  Is it possible to run
OpenJMS as an embedded component in another Java application?
