    JBossMQProvider and HTTPServerILService

    uuu Newbie

      Hi!
      I try to connect MDB to remote topic through HTTP in JBoss 3.2.1.
      I have configured JBossMQProvider in jms-ds.xml


      JBossMQRemoteProvider

      org.jboss.jms.jndi.JBossMQProvider

      HTTPConnectionFactory
      HTTPConnectionFactory
      http://localhost:8080/invoker/JMXInvokerServlet



      I've forced my MDB to use this JMS provider(JBossMQRemoteProvider) by defining <container-configuration>.
      If I use UIL2ConnectionFactory instead of HTTPConnectionFactory it works fine.
      But when I try HTTPConnectionFactory I get the following error:

      .....
      I've looked inside the code of org.jboss.jms.jndi.JBossMQProvider and it seems to me there's a bug.

      public Context getInitialContext() throws NamingException {
      Context ctx = null;
      boolean debug = log.isDebugEnabled();
      if (providerURL == null) {
      // Use default
      if (debug)
      log.debug("no provider url; connecting to local JNDI");
      ctx = new InitialContext(); // Only for JBoss embedded now
      } else {
      // Try another location

      Hashtable props = new Hashtable();
      props.put(Context.INITIAL_CONTEXT_FACTORY,INITIAL_CONTEXT_FACTORY);
      props.put(Context.PROVIDER_URL, providerURL);
      props.put(SECURITY_MANAGER, hasJndiSecurityManager);
      props.put(Context.URL_PKG_PREFIXES, URL_PKG_PREFIXES);

      if (debug)
      log.debug("connecting to remote JNDI with props: " + props);
      ctx = new InitialContext(props);
      }

      if (debug) {
      log.debug("created context: " + ctx);
      }
      return ctx;
      }
      That code tries to get the connection factory using org.jnp.interfaces.NamingContextFactory and it fails to handle communication by HTTP.
      And I found no way to make it use the right context factory.
      Please tell me if there is a way out.
