    JBoss AS6: Mini (Stateful) EJB 3 Example using JBoss and Eclipse

    Phi GF Newbie

      Hi

       

      I switched to JBoss 6.1.0. I created a new JBoss 6.1.0-Server Project:

       

      package ch.my.timer.server;

      import javax.ejb.Remote;

       

      @Remote

      public interface MyTimerRemote {

        void  setRemainingSecs(int seconds);

        float getRemainingSecs();

      }

       

      Here the implementation:

       

      import javax.ejb.Stateful;

       

       

      /**

      * Session Bean implementation class MyTimer

      */

      @Stateful(mappedName="/MyTimer")

      public class MyTimer implements MyTimerRemote {

       

          public MyTimer() {

              this.endTimePoint = System.currentTimeMillis();

          }

       

          private long endTimePoint; // timestamp in milliseconds

       

          @Override

          public void setRemainingSecs(int seconds) {

              long millis = seconds * 1000;

              long now    = System.currentTimeMillis();

              this.endTimePoint = now + millis;

          }

       

          @Override

          public float getRemainingSecs() {

              long now  = System.currentTimeMillis();

              long diff = this.endTimePoint - now;

              float secs = (float) (diff / 1000.0);

              return secs;

          }

       

      }

       

      Starting the Server I get the following messages:

      It does not look as the EJB is deployed.

      Starting the following Client I get the message below:

      import java.util.Hashtable;

      import javax.naming.InitialContext;

      import javax.naming.NamingException;

       

      import  ch.my.timer.server.*;

       

      public class MyTimerTest {

        public static void main(String[] args) {

           try {

              new MyTimerTest().top();

           } catch (NamingException e) {

              // TODO Auto-generated catch block

              e.printStackTrace();

           }

         }

       

         void top() throws NamingException {

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

            env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");    

            env.put(Context.PROVIDER_URL, "localhost:1099");     

            env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );

            InitialContext ctx = new InitialContext(env);

       

            MyTimerRemote str = (MyTimerRemote) ctx.lookup("/MyTimer");

       

            str.setRemainingSecs(3);

            float rem = str.getRemainingSecs();

            System.out.println("Remaining: " + rem);

         }

      }

       

       

      ... here comes the message, which is obvious:

       

      javax.naming.NameNotFoundException: MyTimer not bound

          at org.jnp.server.NamingServer.getBinding(NamingServer.java:771)

          at org.jnp.server.NamingServer.getBinding(NamingServer.java:779)

              ...

       

       

      What am I missing now?
