Also, I'd like to note that our application works fine when used with ActiveMQ. We can stop either or both of the JMS Servers and re-start them without having either of them effect each other. We use the following properties when connecting to JBoss Messaging Server: Hashtable properties = new Hashtable(); properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); properties.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces"); properties.put(Context.PROVIDER_URL, "jnp://localhost:1099"); properties.put(Context.SECURITY_PRINCIPAL, "username"); properties.put(Context.SECURITY_CREDENTIALS, "password"); If you require any further information, please ask for it.
