Hi!
I'm doing a webservice that can be stop using a request, I had followed one
forum here. But I run in a trouble stopping the component in a virtual host set
up.
Here is the first testcase 1, I can stop the server using
http://localhost:8182/stop
///////////////////
// testcase 1 //
///////////////////
public static void main(String[] args) throws Exception{
Component component=new Component();
component.getServers().add(Protocol.HTTP,8182); //Private Port
component.getServers().add(Protocol.HTTP,8183); //Public Port
MyApplication myApp=new MyApplication();
component.getDefaultHost().attach(myApp);
myApp.getContext().getAttributes().put("component", component);
component.start();
}
///////////////////
// MyApplication //
///////////////////
public class MyApplication extends Application {
@Override
public synchronized Restlet createInboundRoot() {
Router router = new Router(getContext());
router.attach("/stop", StopResource.class);
return router;
}
}
///////////////////
// StopResource //
///////////////////
public class StopResource extends ServerResource
{
@Get
public Representation requestGet() throws Exception{
((Component) getContext().getAttributes().get("component")).stop();
return null;
}
}
Here is a testcase 2 that is using a virtual host
///////////////////
// testcase 2 //
///////////////////
public static void main(String[] args) throws Exception{
Component component=new Component();
component.getServers().add(Protocol.HTTP,8182); //Private Port
component.getServers().add(Protocol.HTTP,8183); //Public Port
InetAddress inet = InetAddress.getLocalHost();
String cannonicalHostName = inet.getCanonicalHostName();
component.getContext().getAttributes().put("component", component);
VirtualHost proxyHost = new VirtualHost(component.getContext());
proxyHost.setHostDomain(cannonicalHostName);
proxyHost.setHostPort("8182");
proxyHost.attach("/stop", StopResource.class);
VirtualHost loadBalance = new VirtualHost(component.getContext());
loadBalance.setHostDomain(cannonicalHostName);
loadBalance.setHostPort("8183");
loadBalance.setRoutingMode(Router.MODE_NEXT_MATCH);
component.getHosts().add(proxyHost);
component.getHosts().add(loadBalance);
component.start();
}
Here is the stacktrace for the testcase 2
