Today I tried to get my listener working with a specific context and
added a ServletContextHelper and added a corresponding
@HttpWhiteboardContextSelect annotation to my SCL. Did not work either.
I also tried to change the type to a ServletRequestListener instead of a
ServletContextListener. Still didn't work.
Is there anybody who can help me on this issue?
I'm pretty clueless right now :(
Again this is my setup, maybe someone spots an error in it:

The MySCL class:

@HttpWhiteboardListener
public class MySCL implements ServletContextListener {
@Override
public void contextDestroyed(ServletContextEvent arg0) {
System.out.println("Bye World");
}
@Override
public void contextInitialized(ServletContextEvent arg0) {
System.out.println("Hello World");
}
}
And Apache Felix Web Console still lists my ServletContextListener
under "Failed Listeners" with reason "Invalid".
Is there anybody who knows what this "invalid" means?
Kind regards,
Thomas

Hi Ray,
yes the annotation is processed. At least Apache Felix Webconsole is
showing me this output for my SCL component:
Bundle io.jatoms.osgi.possiblebugs.scl.impl (1)
Implementationsklasse io.jatoms.osgi.possiblebugs.scl.MySCL
Default Status enabled
Aktivierung delayed
Konfigurations Policy optional
Dienst Typ singleton
Dienste javax.servlet.ServletContextListener
PID io.jatoms.osgi.possiblebugs.scl.MySCL
Eigenschaften component.id = 9
component.name = io.jatoms.osgi.possiblebugs.scl.MySCL
osgi.http.whiteboard.listener = true
Sorry, the names are in german. "Eigenschaften" is the properties
section ;)
Kind regards,
Thomas

Thomas did you check that your tool chain processed the annotation
`@HttpWhiteboardListener` into the appropriate service property?

Hi David,
yes this is done via tha @HttpWhiteboardListener annotation. The
webconsole shows me this output for the MySCL component:

Hi Thomas,
The spec states in section 140.7 [1]
"Events are sent to listeners registered in the Service Registry
with the osgi.http.whiteboard.listener service property set to
true"
Did you set this service property?
There is a constant for it in
org.osgi.service.http.whiteboard.HttpWhiteboardConstants [2]
Hope this helps,
David

This is my ServletContextListener:

public class MySCL implements ServletContextListener {
@Override
public void contextDestroyed(ServletContextEvent arg0) {
System.out.println("Destroyed");
}
@Override
