Error during EJB3 call

Question

I have written a simple Ejb program, by looking from

http://mrbool.com/how-to-use-enterprise-java-beans-3-x-based-application-with-websphere-8-5-application-server/28063

The files are

package ejb3.test;
import javax.ejb.Remote;
/**
 * TODO: Document me!
 *
 * @author aprashanth
 *
 */
@Remote 
public interface ITestEJBRemoteInterface { 
    public boolean checkNames(String fsName); 
   }

Implementation Class:

package ejb3.test;

/**
 * TODO: Document me!
 *
 * @author aprashanth
 *
 */
import java.util.Arrays;
import java.util.List;

import javax.ejb.Stateless;
/** * Session Bean implementation class TestEJB */ 
@Stateless 
public class TestEJB implements ITestEJBRemoteInterface { 
    List<String> moListOfNames = Arrays.asList("Kevin","Jiten","Martina","Brian");

    /** * Default constructor. */ 
    public TestEJB() { } 
    /** * Find if the passed name is present in the default list of names * * 
     * 
     * @return */ 
        public boolean checkNames(String fsName) { 
            boolean lboolNamePresent = false; 
            if(fsName != null) 
            { 
                lboolNamePresent = moListOfNames.contains(fsName); 
             } 
            return lboolNamePresent; 
            } 
        }

Ejb-jar.xml:

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd" version="3.1">
  <display-name>TestEJB3 </display-name>
  <ejb-client-jar>TestEJB3Client.jar</ejb-client-jar>
</ejb-jar>

At the client side:

I have created the stub using createStub.bat of IBM.and that jar is imported at the client side.

package ejb31.test;

/**
 * TODO: Document me!
 *
 * @author aprashanth
 *
 */
import java.util.Properties;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

import ejb3.test.ITestEJBRemoteInterface;

public class TestEJBClient { 
    /** * @param args */ 
    public static void main(String[] args) { 
        Properties props = new Properties(); 
        props.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");

        props.put(javax.naming.Context.PROVIDER_URL, "iiop://localhost:2809");

        ITestEJBRemoteInterface loEJB =null; 
        Object lobj; try { InitialContext ctx = new InitialContext(props); 
        lobj = ctx.lookup("checkName"); 
        if (lobj instanceof ITestEJBRemoteInterface) { 
            loEJB = (ITestEJBRemoteInterface) lobj; 
            } 
            String lsName = "Imran"; 
            System.out.println("Is "+ lsName + " present in the list:: "+loEJB.checkNames(lsName)); 
            System.out.println("EJB run successful"); 
            } catch (NamingException e) { 
                e.printStackTrace(); 
                } 
        } 
   }

My project structure and the imported libraries as in the below figure:

At the WAS side, setup steps are as below: Port

Installation Steps

Lastly JndI Configuration.

When I run the client code, I get the following error.

Note: Port and address is correct:

Screen Shot of Security

New error on changing the inbound Configuration

Inside server.jar inside war file

Answer 1

Hmm, you have to look better on your screenshot, as it is clearly visible that Enable Administrative Security is CHECKED.

So you either have to disable SSL in the RMI/IIOP inbound transport configuration, or properly configure your client to use SSL.

Something like this:

<java_install_root>/bin/java  
-classpath com.ibm.ws.ejb.thinclient_8.5.0.jar:<list_of_your_application_jars_and_classes> 
-Djava.naming.provider.url=iiop://<your_application_server_machine_name> 
-Dcom.ibm.SSL.ConfigURL=file:///home/user1/ssl.client.props
-Dcom.ibm.CORBA.ConfigURL=file:///home/user1/sas.client.props
<fully_qualified_class_name_to_run>

For details check the following page - Running the IBM Thin Client for Enterprise JavaBeans (EJB)

UPDATE

Now you have issue in the code. You have to use PortableRemoteObject.narrow for unmanaged clients. Instead of:

   Object lobj; try { InitialContext ctx = new InitialContext(props); 
   lobj = ctx.lookup("checkName"); 
   if (lobj instanceof ITestEJBRemoteInterface) {   // <##### this is the problem
        loEJB = (ITestEJBRemoteInterface) lobj; 
   } 

use:

lobj = initCtx.lookup(ejbJNDIName);
loEJB = (ITestEJBRemoteInterface)        javax.rmi.PortableRemoteObject.narrow(lobj , ITestEJBRemoteInterface.class);
