    Multiple threads on client side for remote EJB calls on Jboss7

    Daniel Jipa Newbie

      Hello

      I am using JBoss EAP 6.4.0.GA (AS 7.5.0.Final-redhat-21) to deploy an ear that contains some stateless ejb 3.

      My problem is in the client side:

       

      public class TestJndi {
      
      
        public static void main(final String[] args) throws AppException {
      
      
        final Hashtable env = new Hashtable();
        env.put("java.naming.factory.initial", "org.jboss.naming.remote.client.InitialContextFactory");
        env.put("java.naming.provider.url", "remote://localhost:4447");
        env.put("java.naming.security.credentials", "c4ca4238a0b923820dcc509a6f75849b");
        env.put("java.naming.security.principal", "capone");
        env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        env.put("jboss.naming.client.ejb.context", "true");
        env.put("jboss.naming.client.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT", "false");
        env.put("org.jboss.ejb.client.scoped.context", "true");
      
      
        try {
        InitialContext ctx = new InitialContext(env);
        final SecurityController o = (SecurityControllerRemote) ctx.lookup(
        "ejb:agency-ear/agency-ejb/SecurityControllerBean!ro.asf.capone.ejb.beans.security.SecurityControllerRemote");
        System.out.println("1outcome: " + o.getServerTimeMillis());
        new Thread(new Runnable() {
        @Override
        public void run() {
        System.out.println("2outcome: " + o.getServerTimeMillis());
        }
        }).start();
      
      
        } catch (final NamingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }
        }
      }
      
      

      The output for this is:

       

      1outcome: 1443468729846
      java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:agency-ear, moduleName:agency-ejb, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@4fc064ca

      I need the multithreading because it's a swing application. Is it a configuration issue? Thank you!
