Hi Justin,
But should it not be enough that the OSGi Activator programmatically
registers the service in the Service Registry with registerService() ?
I am using a code like the following...
package com.me.helloservice;
import java.util.Dictionary;
import java.util.Hashtable;
import com.me.helloservice.impl.HelloServiceImpl;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import org.osgi.framework.Constants;
import org.osgi.framework.ServiceRegistration;
public class Activator implements BundleActivator {
private ServiceRegistration registration;
public void start(BundleContext context) throws Exception {
HelloService greeter = new HelloServiceImpl();
final Dictionary<String, Object> props = new Hashtable<String,
Object>();
props.put(Constants.SERVICE_DESCRIPTION, "Greatest Service on
Earth");
props.put(Constants.SERVICE_VENDOR, "Me");
registration =
context.registerService(HelloService.class.getName(), greeter, props);
System.err.println("HelloService Started");
}
public void stop(BundleContext context) throws Exception {
System.err.println("HelloService Stopped");
registration.unregister();
}
}
