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.
