Hi All ...

    code:

My code goes like this (I have put it in a servlet) ::


    code:

      	
    	// set the JNDI Properties
    		Properties props = new Properties();
     	    props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
     	    props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
       	    props.setProperty("java.naming.provider.url", "localhost:1099");
    //   	    Session mySession= SessionManager.getManager().getSession("comics");
    //   	    ((JNDIConnector)((Session) mySession).getLogin().getConnector()).setLookupType(JNDIConnector.STRING_LOOKUP);
            
       	    
       	 
        // invoke the session bean object 	
       	    try {
       	        Context context = new InitialContext(props);
    //    	    DatabaseLogin login = (DatabaseLogin)mySession.getProject().getLogin();
    //    	    javax.sql.DataSource ds = (javax.sql.DataSource) context.lookup("java:system");
    //    	    System.out.println("Data Source "+ds);
    //    	    JNDIConnector connector = new JNDIConnector(ds);
    //    	    login.setConnector(connector);
       	        
    			src.FirstSession myBeabObj = (src.FirstSession) context.lookup("sample123/FirstSessionBean/remote");
    			myBeabObj.sayHello(Name, Age, Dept);
       	        PrintWriter pwWriter = response.getWriter();
       	        pwWriter.println("Before calling Persistence");
                
       	        
    //   	        new entityCaller().persistEntity(Name, iAge);
       	        
       	        
       	        pwWriter.println("After calling Persistence");
    			pwWriter.println("new Deployment"+System.currentTimeMillis());
    			pwWriter.println("You submitted Age"+Name);
    			pwWriter.println("You submitted Age"+Age);
    			pwWriter.println("You submitted Age"+Dept);
    //			pwWriter.println("The Bean returned this value"+myBeabObj.sayHello(Name , Age , Dept ));
    			System.out.println("Finished Transaction");
    		} catch (NamingException e) {
    			
    			System.out.println("Exception Reached");
    			e.printStackTrace();
    		}// end of try catch block
