    javax.naming.NameNotFoundException: ejb not bound

    Jose Alvarez de Lara Novice

      Hi,

      I am trying to develop a CMP EJB 2.0 application and I found two problems,
      both of them are the same listed below:

      java.rmi.ServerException: EJBException:; nested exception is:
       javax.ejb.EJBException: javax.naming.NameNotFoundException: ejb not bound
      


      The first one I have solved with the following code on the client,

      // Get an initial context
       InitialContext jndiContext = new InitialContext(properties);
       System.out.println("Got client context");
      
       // Get a reference to the Bean
       //Object ref = jndiContext.lookup("java:comp/env/ejb/Bookstore"); //java:comp/env/ejb/Bookstore
       //System.out.println("Got reference");
      
       // Get a reference from this to the Bean's Home interface
       BookstoreHomeRemote home = (BookstoreHomeRemote)
       PortableRemoteObject.narrow (jndiContext.lookup("BookstoreBean"), BookstoreHomeRemote.class);
      


      But when I use JNDI on the Session Bean to call the Entity Bean, then theserver throws the exception above. The code is,

      public class BookstoreBean implements SessionBean{
      
       CMPBooksHomeRemote booksHome;
      
       public void ejbCreate() throws CreateException {
       }
      
       public Collection booksList(){
       Vector books = new Vector();
      
       try{
       Context ctx = new InitialContext();
       System.out.println("Got context in Session Bean");
      
       booksHome = (MPBooksHomeRemote) ctx.lookup("java:comp/env/ejb/CMPBooksHomeRemote");
       System.out.println("Got booksHome");
      
       books = (Vector)booksHome.findAll();
      
       } catch(NamingException ne){
       throw new EJBException(ne);
       } catch(RemoteException re){
       throw new EJBException(re);
       } catch (FinderException fe) {
       throw new EJBException(fe);
       }
       return books;
       }
      
       public void ejbRemove(){}
       public void ejbActivate(){}
       public void ejbPassivate(){}
       public void setSessionContext(SessionContext sc){}
      }
      


      This is the log,

      2008-10-05 10:57:41,887 INFO [STDOUT] Got context in Session Bean
