--------------------------------------------------------------
Hey all. I'm having a really difficult time with EJB3.

I have a server running a simple calculator demo. I am trying to create a Mule ESB call into it. If I run my calculator client standalone, it works fine. If I move my calculator client to Mule, it fails.

One hint I have is that running standalone, my EJB call returns a class $Proxy2 and running on Mule, it returns class javax.naming.Reference. Any Ideas



OUTPUT:

If I run my EJB Client on my local client, it works just fine:
Initializing
CLASS:class $Proxy2
Loaded Calculator Bean
 public final float $Proxy2.division(float,float), public final float $Proxy2.subtract(float,float), .....public final void java.lang.Object.wait() throws java.lang.InterruptedException public final float $Proxy2.division(float,float), public final float $Proxy2.subtract(float,float), .....public final void java.lang.Object.wait() throws java.lang.InterruptedException
Result:-3.0



But if I run my EJB Client on my Mule Server, it breaks:
Initializing
CLASS:class javax.naming.Reference
Loaded Calculator Bean
 public void javax.naming.Reference.add(int,javax.naming.RefAddr), public void javax.naming.Reference.add(javax.naming.RefAddr), .....  public void javax.naming.Reference.add(int,javax.naming.RefAddr), public void javax.naming.Reference.add(javax.naming.RefAddr), ..... 
java.lang.NoSuchMethodException: javax.naming.Reference.subtract(float, float)
    at java.lang.Class.getMethod(Unknown Source)




CODE:

Here's my code. Like I said, it's identicle on both my Mule Server and Eclipse Client.

package com.allurent;

import java.lang.reflect.Method;
import java.util.Arrays;
import java.util.Hashtable;

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

import org.mule.api.MuleEvent;
import org.mule.api.MuleException;

public class CalculatorLocal implements org.mule.api.processor.MessageProcessor
{
    private static Object calculator = null;

    public static void jspInit() {
        System.out.println("Initializing");

            Hashtable<String, String> t = new Hashtable<String, String>();

            t.put("java.naming.provider.url", "jnp://localhost:1099");
            t.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
            t.put("java.naming.factory.initial", "org.jboss.naming.NamingContextFactory");

            InitialContext ic = null;
            try {
                ic = new InitialContext(t);
            } catch (NamingException e) {
                e.printStackTrace();
            }

            Object temp = null;
            try {
                temp = ic.lookup("example/CalculatorBean/remote");
            } catch (NamingException e) {
                e.printStackTrace();
            }

            System.out.println("CLASS:"+temp.getClass());
            calculator = temp;    
            System.out.println("Loaded Calculator Bean");
    }

    public static void jspDestroy() {
        calculator = null;
    }

    public static void main (String [] args)
    {
        args = new String[3];
        args[1] = "12";
        args[2] = "15";
        args[0] = "subtract";


        jspInit();

        try {
            String s1 = args[1];
            String s2 = args[2];
            String s3 = args[0];

            if ( s1 != null && s2 != null ) {
                Float num1  = new Float(s1);
                Float num2  = new Float(s2);

                System.out.println(Arrays.toString(calculator.getClass().getMethods()));

                Class<? extends Object> c = calculator.getClass();
                Method m = c.getMethod(s3, float.class, float.class);
                Object value = null;
                value = m.invoke(calculator, num1.floatValue(), num2.floatValue());

                System.out.println("Result:"+value.toString());
            }

        }
        catch (Exception e) {
            e.printStackTrace ();
        }
        jspDestroy();
    }

    @Override
    public MuleEvent process(MuleEvent event) throws MuleException {
        CalculatorLocal.main(new String [] {"test","test2"});
        return null;
    }
}


I've been working on this for 3 days now, and I'm at my wit's end.

Thanks,
-Rob
