Thomas Driessen commented on FELIX-6049:
----------------------------------------
ListenersTracker#getServiceInfo is called.
I searched a little bit and I think I found the reason why this is not working:
Within ListenerInfo constructor there is the following statement:
this.enabled = "true".equalsIgnoreCase(this.getStringProperty(ref,
HttpWhiteboardConstants.HTTP_WHITEBOARD_LISTENER));
This one returns false although the value is actually set to "true".
This is because getStringProperty() returns null if the value asked for is not
of type String.
The attribute HttpWhiteboardConstants.HTTP_WHITEBOARD_LISTENER is of type
Boolean, so this statement evaluates to "true".equalsIgnoreCase(null);
The "enabled" value is then used in WhiteboardManager#addWhiteboardService to
determine if the the service is actually valid, which it is not because it is
not enabled.

> Key: FELIX-6049
> URL: https://issues.apache.org/jira/browse/FELIX-6049
> Project: Felix
> Issue Type: Bug
> Components: HTTP Service
> Affects Versions: http.jetty-4.0.6
> Reporter: Thomas Driessen
> Priority: Major
> Fix For: http.jetty-4.0.8
>
>
> I just tried to get a ServletContextListener to work, but did not succeed,
> although everything is done as defined by the spec.
>
> Here you can find a minimal example of my setup
> [https://github.com/Sandared/io.jatoms.osgi.possiblebugs.scl]
>
> The Servlet I'm registering is working fine, but the ServletContextListener
> that I registered too is never called.
> Even if I call getServletContext() from within the Servlet, my Listener is
> never called.
> I would have expected the ServletContextListener to be called at least once,
> after a DefaultServletContext has been created by the ServletContainer
>
> Additional Information:
> The MySCL.java:
>
> @Component
> @HttpWhiteboardListener
> public class MySCL implements ServletContextListener {
> @Override
> public void contextDestroyed(ServletContextEvent arg0) {
> System.out.println("Destroyed");
> }
> @Override
> public void contextInitialized(ServletContextEvent arg0) {
> System.out.println("Initialized");
> }
> }
