RE: EJB JNDI lookup

Thanks Rakesh and Manu for your information. Now my look up doesn’t work and it throws an exception NamingException: /java:comp/env/ejb/helloworld-ejb/HelloBean not found.

 

My openejb-jar.xml referes jndi name as

 

<enterprise-beans>

        <session>

            <ejb-name>HelloBean</ejb-name>

            <jndi-name>ejb/helloworld-ejb/HelloBean</jndi-name>

        </session>

</enterprise-beans>

 

And I am trying looking up it in my client class as:

Object homeObject = ctx.lookup("java:comp/env/ejb/helloworld-ejb/HelloBean");

 

I also tried with different options like:

Object homeObject = ctx.lookup("ejb/helloworld-ejb/HelloBean"); or

Object homeObject = ctx.lookup("HelloBean");

 

Either one did not work.

 

Am I missing some thing else?

 

Thanks,

-Siraj

You have not specified the system properties to get the InitialContext.

Use the following code to get the InitialContext.

 

Properties props = new Properties();

props.put("java.naming.factory.initial","org.openejb.client.RemoteInitialContextFactory");

props.put("java.naming.provider.url", "127.0.0.1:4201");

props.put("java.naming.security.principal", "system");

props.put("java.naming.security.credentials", "manager");

 

javax.naming.InitialContext ctx = new javax.naming.InitialContext(props);

 

With Regards,

Rakesh Ranjan

Hi All,

 

I have deployed a hello world application (helloworld.ear) on Geronimo 1.0 M5. I have written a java client class to test my application. But I am getting following error message from the client code:

 

NamingException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

 

It tells that I have to set java.naming.factory.initial and java.naming.provider.url in the jndi.properties. What would be the values to be specified for them for Geronimo server?

 

 

This is my sample client code:

 

/*

 * A simple client for accessing an EJB.

 */

 

public class HelloClient

{

  public static void main(String[] args)

  {

    System.out.println("client started...");

    try {

      javax.naming.Context ctx = new javax.naming.InitialContext();

 

      // This is for use with com.evermind.server.ApplicationClientInitialContextFactory

      System.out.println("looking up...");

      Object homeObject = ctx.lookup("java:comp/env/HelloBean");

 

      // Narrow the reference to HelloHome

      HelloHome home =

            (HelloHome) PortableRemoteObject.narrow(homeObject, HelloHome.class);

 

      // Create remote object and narrow the reference to Hello.

      Hello remote =

            (Hello) PortableRemoteObject.narrow(home.create(), Hello.class);

 

      System.out.println(remote.sayHello("James Earl"));

 

    } catch(NamingException e) {

      System.err.println("NamingException: " + e.getMessage());

    } catch(RemoteException e) {

      System.err.println("RemoteException: " + e.getMessage());

    } catch(CreateException e) {

      System.err.println("FinderException: " + e.getMessage());

    }

  }

}

 

 

Thanks in advance,
