System.out.println and EJBs

Question

Hi,
I'm trying to develop an application that has 2 main components:
1) A stateless session EJB, which is called by the container timer service periodically and makes some DB uptades.
2) A servlet which basically calls the create method in the EJB.
I've implemented a prototype of the app and the servlet code looks like this:
try {
Context context = new InitialContext();
MyClassLocalHome home = (MyClassLocalHome)PortableRemoteObject.narrow(
               context.lookup("java:comp/env/ejb/MyClass"),
          MyClassLocalHome.class);
System.out.println("Narrowed");
MyClassLocal timer;
// create a new instance
timer = home.create();
System.out.println("Created!");
In the ejbCreate() in MyClass callback, all I have is a System.out.println("ejbCreate() called") to show the method was called.
My problem is the even though the servlet code runs without errors and I can see the output in the application server's SystemOut.log, I can't find "ejbCreate() called" message. Am I looking in the wrong place? Am I doing something wrong?
Thanks in advance.

Hi Pedro,
You're not necessarily doing something wrong. Where are you actually invoking a business method on the Stateless Session bean? In the Stateless Session Bean lifecycle, the actual bean instance creation is not required to be linked to the Home.create() call. That's because Stateless Session bean instances have no client-specific state. The container can delay the bean instance creation until an actual business method is called. Only then would the bean instance's ejbCreate method be called.
