Re[7]: ServletContextListener not working?
Posted by Thomas Driessen <th...@gmail.com>.
For all of you who are having the same issue in felix.http 4.0.6:
Change the ServletContextListener component from this
@Component
@HttpWhiteboardListener
public class MySCL implements ServletContextListener
to this:
@Component(property= {HttpWhiteboardConstants.HTTP_WHITEBOARD_LISTENER +
"=true"})
public class MySCL implements ServletContextListener
The version of felix.http affected is 4.0.6. Hopefully this will be
fixed in 4.0.8
An explanation can be found here:

Re[6]: ServletContextListener not working?
Posted by Thomas Driessen <th...@gmail.com>.
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:
@Component
@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

Re[5]: ServletContextListener not working?
Posted by Thomas Driessen <th...@gmail.com>.
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

Re: Re[3]: ServletContextListener not working?
Posted by Raymond Auge <ra...@liferay.com>.
Thomas did you check that your tool chain processed the annotation
`@HttpWhiteboardListener` into the appropriate service property?
