How to bind a bean's method with package in actionListener?

Question

I am pretty much newbie to Java/JSF technology and I've been trying to do simple UIs to understand how things are going on in Java/JSF world.

Now I want to bind a ManagedBean's method with its package name to a CommandButton's actionListener.

Example:

index.xhtml

...
<h:commandButton actionListener="#{com.acme.myclass.MyMethod}" ...
...

MyClass.java

package com.acme;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;

@ManagedBean
@RequestScoped

public class MyClass {

    public MyClass() {
        // Constructor
    }

    public void MyMethod() {
        // Do some job
    }

}

I tried to bind the method as the given example above but the method is not called. Besides I don't see my packages in Netbeans's little autocomplete window. If I bind the method in #{class.method} format (as all given examples on the internet) it works.

Is there a way to achieve this?

Why do I need to do this?

While projects are getting larger and larger naming classes getting harder and harder. So, I think that same class names in different packages make life easier.

JSF doesn't permit that kind of actionlistener binding, simple. The only semblance to what you have in the JSF world, is a standalone implementation of the ActionListener interface, with which you can then supply a FQN:

  <h:commandButton>
       <f:actionListener type="com.you.YourActionListenerImpl" />
  </h:commandButton>

Where YourActionListenerImpl will be a class implementing ActionListener as mentioned previously

As to why you want to do this, I think you're overstating the cost of naming - it's not that hard. Massive, sprawling projects are getting along just fine (look at the Spring project for example) with the naming of Java artifacts.
