i am trying to use zk instead of jsf.
in my jsf-controller-classes (managed beans) i use the @EJB annotation to inject my controller with my ejb-DAOs.

it works perfectly. EJB-sepc says you can only use this dependency-injection (@EJB) with managed classes.

now i try to use the injection in my zk-controller, which basically works as a data-binding manager to submit new form-data.
(as you demenstraded in your latest data-binding smalltalk).

no i try to inject this class with my ejb-DAO as well, but it doesn't work. (@EJB annotation doesn't do anything, it just get ignored.).

#1. how can i make my zl-controller class "managed" like a jsf-managed-bean ?

#2. any other suggestions ?

thanks for any help.

Can you provide a "very" simple example and let's see what we can do? (In jsf form and in zk form)

I have the same problem.
Here is a simple Window what does not work propertly:
package test;

import org.zkoss.zul.*;
import org.zkoss.zk.ui.*;
import org.zkoss.zk.ui.event.*;
import org.zkforge.dojo.*;
import javax.ejb.*;
import mario.*;

public class Main extends Window

MarioLocal m;

private Button b = new Button("test");

public Main()
super(null, "none", false);

b.addEventListener(Events.ON_CLICK, new EventListener()
public void onEvent(Event evt)
b.setLabel("" + m);

MarioLocal is the local interface to a stateless EJB in the same EAR.
when the button is pressed, m is still null.
If I implement the same in JSF m is correctly retrieved.

I cannot attach the whole zip, if you need I can upload it.

thanks for any help.

Yeah, I think ZK should aware on Java EE 6, by providing EJB Annotation to access Local SessionBean. We do need it.
