Hi,
Has anyone ever tested Grizzly's HttpService with a Jersey ServletContainer? I have tried several different ways and have failed to get Jersey to locate my resource file. I see an Embedded Grizzly test in the Jersey tests, but not one with HttpService. I see use of the Jersey client in the Grizzly tests, but no use of the Jersey servlet.
I'm using Felix BTW.
Here's my code and the result from the startup log file.
package camiant.osgi.msr.rest;
import java.util.Dictionary;
import java.util.Hashtable;
import org.osgi.framework.ServiceReference;
import org.osgi.service.http.HttpService;
import org.osgi.util.tracker.ServiceTrackerCustomizer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import com.sun.jersey.api.core.PackagesResourceConfig;
import com.sun.jersey.spi.container.servlet.ServletContainer;
public class RestGrizzlyServiceTrackerCustomizer implements ServiceTrackerCustomizer {
private static final Logger LOGGER = LoggerFactory.getLogger(RestGrizzlyServiceTrackerCustomizer.class);
@Override
public Object addingService(ServiceReference serviceRef) {
LOGGER.info("Adding service: " + serviceRef.getBundle().getSymbolicName());
Dictionary<String, String> JERSEY_INIT_PARAMS = new Hashtable<String, String>();
// package based
JERSEY_INIT_PARAMS.put(PackagesResourceConfig.PROPERTY_PACKAGES, "camiant.osgi.msr.rest.resource");
// application based
//JERSEY_INIT_PARAMS.put("javax.ws.rs.Application", "camiant.osgi.msr.rest.MSRRestApplication");
// resource based
// JERSEY_INIT_PARAMS.put("com.sun.jersey.config.property.classnames", Resource1.class.getCanonicalName());
// JERSEY_INIT_PARAMS.put("com.sun.jersey.config.property.resourceConfigClass", ClassNamesResourceConfig.class.getName());
HttpService grizzlyService = (HttpService)serviceRef.getBundle().getBundleContext().getService(serviceRef);
try {
ServletContainer jerseyServletContainer = new ServletContainer();
grizzlyService.registerServlet("/rs", jerseyServletContainer, JERSEY_INIT_PARAMS, null);
} catch (Exception e) {
e.printStackTrace();
grizzlyService = null;
}
return grizzlyService;
}
@Override
public void modifiedService(ServiceReference serviceRef, Object httpService) {
LOGGER.info("Modifying service: " + serviceRef.getBundle().getSymbolicName());
removedService(serviceRef, httpService);
addingService(serviceRef);
}
@Override
public void removedService(ServiceReference serviceRef, Object httpService) {
LOGGER.info("Removing service: " + serviceRef.getBundle().getSymbolicName());
serviceRef.getBundle().getBundleContext().ungetService(serviceRef);
httpService = null;
}
}

So, I've tried package-based, resource-based, and application methods of trying to get Jersey to locate my resource file. No luck at all. Am I not bundling things such that Jersey can see them (i.e. classload issue?).
Any help would be greatly appreciated.
Thanks,
Dave
P.S. here's the ps...
