The web console seems to be available. Requesting
"http://localhost:8080/system/console/bundles"; leads to:
'A username and password are being requested by http://localhost:8080. The site
says: "OSGi Management Console"'
So i assume the HttpService is available.
i rewrote the EmbeddedServletActivator to use a ServiceTracker
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
@Override
public void start(BundleContext context) throws Exception
{
httpServiceTracker = new ServiceTracker(context,
HttpService.class.getName(), null);
httpServiceTracker.open();
System.out.println("Looking for HttpService");
final HttpService httpService =
(HttpService)httpServiceTracker.getService();
if(httpService!=null) {
System.out.println("Found HttpSerice");
httpService.registerServlet(ALIAS, new HelloWorldServlet(), null,
null);
System.out.println("registered "+ALIAS+" with HttpService");
}else{
System.out.println("httpServiceTracker.getService() returned null");
}
}
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
which lead to
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Starting bundle [com.mobenga.HelloWorldServletEmbedded]
Looking for HttpService
httpServiceTracker.getService() returned null
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
so no change there.

Betreff: Re: No HttpService available
Hi
Can you verify the HttpService is available at all in the framework ? (You
might try to access the web console)
If not, you might have an issue to not properly setup the Http Service bridge:
This requires wiring from the servlet which is actually deployed in the servlet
container. See [1] and the linked examples for details.
