    look up jndi problem

    igal israilevich Newbie

      I have communication ( may be JNDI ?) problems even by testing the simplest EJB program
      My Ejb Bean:

      @Stateless(name = "Test1")
      public class Test1 implements Test1Remote {
      
       /**
       * Default constructor.
       */
       public Test1() {
       // TODO Auto-generated constructor stub
       }
      
       public String echo (String str){
       System.out.println("Test1:echo str ="+str);
       return str;
       }


      My Remote:


      @Remote
      public interface Test1Remote {
      
       public String echo (String str);
      
      }


      My Client:

      Code:
      public class Main {
       public static void main(String[] args) {
       try {
       InitialContext ctx = CmsEjbUtil.getInitialCotext();
       Test1Remote dao = (Test1Remote) ctx.lookup("Test1/remote");
       String str =dao.echo("Hello World");
       System.out.println(str);
       } catch (NamingException e) {
      
       e.printStackTrace();
       }
      
       }


      CmsEjbUtil.getInitialCotext() :

      Code:

      public static InitialContext getInitialCotext() throws NamingException {
       Hashtable props = new Hashtable<String, String>();
       props.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
       props.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
       props.put("java.naming.provider.url", "jnp://localhost:1099");
       return new InitialContext(props);
       }


      but when I run client I get the following stack trace:
      Code:
      javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost:109
