This tutorial explains ou how to code a Java EJB Client for a stateful EJB 3 deployed on Weblogic 12c.

This article is using:

Eclipse Java EE IDE for Web Developers, Version: Neon.3 Release (4.6.3)
Java 8

The Enterprise Java Bean is deployed on the Oracle WebLogic 12c.

You have to add to your new Java Project the MyEJB project to the build path:

You have to add to your new Java Project the weblogic.jar and wlclient.jar (are in the WebLogic download package):

Now it time for coding. Here is the class I added to the project:

import java.util.Hashtable;
 
import javax.naming.Context;
import javax.naming.InitialContext;
 
public class RunTest {
 
    public static void main(String[] args)throws Exception {  
 
        System.out.println("Start EJB3 Client for connecting to Weblogic");
          
           final Hashtable jndiProperties = new Hashtable();
         
           jndiProperties.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
           jndiProperties.put(Context.PROVIDER_URL,"t3://localhost:7001");
         
           Context ctx = new InitialContext(jndiProperties);
           System.out.println("Initial Context created");
         
           AddIntegersRemoteInterface addIntegers =
                   (AddIntegersRemoteInterface) ctx.lookup("AddIntegers#AddIntegersRemoteInterface");
         
           System.out.println("lookup successful");  
         
           //Remote EJB function calls   
           addIntegers.addValue(1);
           addIntegers.addValue(1);
            
           System.out.println(addIntegers.returnSum());  
         
           System.out.println("EJB3 Client : END");
    }
}

I run the project as "Java Application" 2 times and here is the result of the last run:
