Error getting EJB reference

[Khaled Mahmoud]

Hi all,
I am using "Sun Application Server 9.0" with Netbeans 5.5 IDE.
I have developed a simple EJB called AccesDriveCBean.

Here are the class names and interfaces for this bean.

    
 
 Package name :  org.khaledinho.learning.sun.java.certifications.scbcd
 Bean class name : AccessDriveCBean
 Local Interface class name : AccessDriveCLocal
 Remote Interface class name : AccessDriveCRemote
 
 All these classes and interfaces belong to the package specified as above.
 

I have successfully deployed this bean into the "Sun Application Server 9.0"
and logs of server shows that the JNDI name of the deployed bean is as following :

**RemoteBusinessJndiName: org.khaledinho.learning.sun.java.certifications.scbcd.AccessDriveCRemote; remoteBusIntf: org.khaledinho.learning.sun.java.certifications.scbcd.AccessDriveCRemote

JNDI name is : org.khaledinho.learning.sun.java.certifications.scbcd.AccessDriveCRemote

When i tried to get a reference to this enterprise from a remote client i got the following exception :

  
javax.naming.NameNotFoundException [Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL :-o	 mg.org/CosNaming/NamingContext/NotFound:1.0]

Here is the code for the Java Client Application

    
 Hashtable connProps = new Hashtable();
        Context initCntxt = null;
        
        try {
            
            connProps.put("java.naming.factory.initial","com.sun.jndi.cosnaming.CNCtxFactory");                                 
            connProps.put(Context.PROVIDER_URL,"iiop://localhost:3700");            
            
            initCntxt = new InitialContext(connProps);
            initCntxt.lookup("org.khaledinho.learning.sun.java.certifications.scbcd.AccessDriveCRemote");
        } catch(Exception exc) {
            System.out.println(exc.getMessage());
            exc.printStackTrace();
        }

I still don't know what was wrong in my first approach in getting a reference to the remote EJB. Mosts posts and topics I read on the net point to my way in obtaining a reference to a remote EJB.

Any ideas regarding any of the shown exceptions.

Hi,

The second way worked successfully. I restarted my PC and when I tried to a get a reference to stateless session bean the operation was successful.
Looks like there was a problem in the "Sun Application Server" on the port 3700.
