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 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,

I've investigated this further and in the Apache Felix Web Console my listener is listed under the "Failed Listeners". As reason "Invalid" is

I do not know what I'm doing wrong :(

This is my ServletContextListener:

public class MySCL implements ServletContextListener {

     public void contextDestroyed(ServletContextEvent arg0) {

     public void contextInitialized(ServletContextEvent arg0) {


Any idea what I'm missing?

Kind regards,
