    Cant' lookup an EJB via JNDI into java application under EAP6

      I have Tow separated applications :

      1=> The first named : my-services (contains Remote Interfaces and Implementations) and this is an example:

       

      @Remote(IPersonRemote.class)
      @Local(IPersonLocal.class)
      @Stateless
      public class PersonFactory implements IPersonLocal, IPersonRemote {
                private static final long serialVersionUID = 1L;
                @Override
                public voif findByCostumer(final String cId) {
                System.out.println("The client id is "+cId);
           }

      }



      I marked a clean and install (maven) and that generated a jar file in the target folder and I deployed it on the jboss EAP6:

      my-services.jar

      my-services.jar.deployed

      2=> I have a another java project named : MyProject with a main methode like this:

       

      public class RemoteEJBClient {

      public static void main(String[] args) throws Exception {
        invokeStatelessBean      ();
      }

      private static void invokeStatelessBean() throws NamingException {

               final Hashtable jndiProperties = new Hashtable();
         jndiProperties      .put(Context.URL_PKG_PREFIXES,"org.jboss.ejb.client.naming");
               final Context context = new InitialContext(jndiProperties);
               final String appName = "";
               final String moduleName = "my-services-all";
               final String distinctName = "";
               final String beanName = PersonFactory.class.getSimpleName();
               final String viewClassName = IPersonFactoryRemote.class.getName();
               final IPersonFactoryRemote statelessRemoteCalculator = (IPersonFactoryRemote) context
               .lookup("ejb:" + appName + "/" + moduleName + "/"
               + distinctName + "/" + beanName + "!" + viewClassName);
       }

      }



      but when I try to execute the programme it gives me the following errors :


      DEBUG org.jboss.logging - EjbNamingContext.java:59 - Logging Provider: org.jboss.logging.Log4jLoggerProvider
      INFO org      .jboss.ejb.client - EJBClient.java:45 - JBoss EJB Client version 1.0.24.Final-redhat-1
