Remote ejb call failed after successful calls

问题

I've a strange problem. I've install JbossAS 7.1.1 and deployed my ear file successfully.

My client is running to tomcat 6.035.

I can make successful EJB calls to my jboss deployment - but one specific EJB calls fails.

my client environment setup is as below :-

  Hashtable<String, String> env = new Hashtable<String, String>();

  env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jboss.naming.remote.client.InitialContextFactory");
  env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
  env.put(Context.PROVIDER_URL, "remote://localhost:4447");
  env.put(Context.SECURITY_PRINCIPAL, "abc");
  env.put(Context.SECURITY_CREDENTIALS, "123");
  env.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");
  env.put("jboss.naming.client.ejb.context", "true");

  env.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
  env.put("remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");
  //env.put("remote.connection.x1.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS", "false");

  logger.debug("Added security ");

  try {
    ctx = new InitialContext(env);
  } catch (NamingException e) {
    logger.error("Can't get initial context.");
    e.printStackTrace();
  }

The stracktrace is very strange. Its looking for RemoteNamingEJBClient Please help - I'm out of idea.

I've solved this problem by adding

ejb-client module in remote-naming module

this issue is tracked here-
