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

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), .....

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,
