This actually looks more problematic than it first appears. The EJB
control (and others) rely on some of the lifecycle methods like
onAcquire and onRelease to get and release their resources.
So unfortunately I don't know of a quick answer to that problem
outside of a control container, it will take some digging. If others
have tips on how to accomplish this or where to look that would be
helpful.

Hi Chris,
I'm retyped the code using programmatic and declarative mechanism to instance
the control.
Unfortunately calling the two method (welcomeDeclarative, welcomeProgrammatic)
I'm getting in both case the same exception:
org.apache.beehive.controls.api.ControlException: Control initialization
failure[Contextual service
org.apache.beehive.controls.api.context.ResourceContext is not available]
Do you have any advice to solve this (two) problems (declarative (if is
possible) and programmatic)?
This is my client class:
package controls;
import org.apache.beehive.controls.api.bean.Control;
import org.apache.beehive.controls.api.bean.Controls;
import org.apache.beehive.controls.api.context.ControlThreadContext;
public class Prova {
@Control
private ProvaSessioBeanCtrl provaSessioBeanCtrl;
public Prova() throws ClassNotFoundException {
try {
Controls.initializeClient(null, this, null);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
public String welcomeProgrammatic(String name) {
String ritorno = "bubububu";
try {
ProvaSessioBeanCtrlBean provaSessioBeanCtrl =
(ProvaSessioBeanCtrlBean) Controls
.instantiate(ProvaSessioBeanCtrlBean.class, null,
ControlThreadContext.getContext(),
"provaSessioBeanCtrl");
ritorno = provaSessioBeanCtrl.welcomeName(name);
} catch (Exception ex) {
//cnfe.printStackTrace();
ritorno = "Exception by Programmatic: " + ex.toString();
}
return ritorno;
}
public String welcomeDeclarative(String name) {
String ritorno = "bububub";
try {
ritorno = provaSessioBeanCtrl.welcomeName(name);
} catch (Exception cnfe) {
//cnfe.printStackTrace();
ritorno = "Exception by Declarative: " +
cnfe.toString();
}
return ritorno;
}
}
