Hi Steinar.
The problem is, that JSF doesn`t provide any means to handle OSGi services.
CDI would solve this but at the moment it is not possible to use
CDI-Annotations in a JSF-Controller (UkelonnController) because JSF inside
Pax-Web cannot resolve beans within an BeanManager from an EL-Expression
[1]. If this bug would be solved you could just use the CDI-Extensions
provided by Pax-CDI.
IMHO, the only solution at the moment is to get an OSGi-service using the
framework-api, execute it, and release it. With Java 8 you can achieve this
without a lot of noise using Lambdas
public static void executeWithOsgiServiceDelegate(Consumer<
OsgiServiceDelegate> x){
final BundleContext context = FrameworkUtil.getBundle(this.getClass()).
getBundleContext();
// get-service, execute function, and unget-service
ServiceReference<OsgiServiceDelegate> serviceRef = context.
getServiceReference(OsgiServiceDelegate.class);
if (serviceRef != null) {
OsgiServiceDelegate service = context.getService(serviceRef);
if (service != null) {
x.accept(service);
service = null;
}
context.ungetService(serviceRef);
}
}
Now you can use this like
executeWithOsgiServiceDelegate(service -> this.var = service.delegateMethod
());
