POProblem investigating JmDNS3.4.1 jar
text
Body
copied!<p>I'm newbie here. I'm dealing with my first program using osgi bundles and JmDNS. After adding JmDNS 3.4.1 jar to my project, I'm testing the following basic code:</p> <p>My Activator:</p> <pre><code>package test.discoverservice; import java.io.IOException; import test.DiscoverServices; import javax.jmdns.JmDNS; import javax.jmdns.ServiceTypeListener; import org.equinoxosgi.jmdns.dev.discoverservice.DiscoverServices.SampleListener; import org.osgi.framework.BundleActivator; import org.osgi.framework.BundleContext; public class JmdnsActivator implements BundleActivator { public void start(BundleContext context) throws Exception { System.out.println("Launching"); try { System.out.println("step 1"); final JmDNS jmdns = JmDNS.create(); System.out.println("step 2"); jmdns.addServiceListener("_http._tcp.local.", new SampleListener()); // jmdns.close(); // System.out.println("Done"); } catch (IOException e) { e.printStackTrace(); } } public void stop(BundleContext context) throws Exception { System.out.println("Terminating"); } } </code></pre> <p>and here is the bundle:</p> <pre><code>package test.discoverservice; import javax.jmdns.ServiceEvent; import javax.jmdns.ServiceListener; public class DiscoverServices { static class SampleListener implements ServiceListener { @Override public void serviceAdded(ServiceEvent event) { System.out.println("Service added : " + event.getName() + "." + event.getType()); } @Override public void serviceRemoved(ServiceEvent event) { System.out.println("Service removed : " + event.getName() + "." + event.getType()); } @Override public void serviceResolved(ServiceEvent event) { System.out.println("Service resolved: " + event.getInfo()); } } } </code></pre> <p>when I run the code, I get :</p> <pre><code>osgi> Launching step 1 </code></pre> <p>and then it stops, so I guess there is a probelm with the creation of the JmDNS instance.. Any idea please?</p> <p>Note that if I don't use a bundle with an activator (simple program with main) everything works properly </p> <pre><code>import java.io.IOException; import javax.jmdns.JmDNS; import javax.jmdns.ServiceEvent; import javax.jmdns.ServiceTypeListener; public class DiscoverServiceTypes { static class SampleListener implements ServiceTypeListener { @Override public void serviceTypeAdded(ServiceEvent event) { System.out.println("Service type added: " + event.getType()); } public void subTypeForServiceTypeAdded(ServiceEvent event) { System.out.println("SubType for service type added: " + event.getType()); } } public static void main(String[] args) { try { JmDNS jmdns = JmDNS.create(); System.out.println("JmDNS created !!"); jmdns.addServiceTypeListener(new SampleListener()); // jmdns.close(); // System.out.println("Done"); } catch (IOException e) { e.printStackTrace(); } } } </code></pre> <p>PS: I'm running it on Windows</p>
