In Java EE 6, how do I get the URL of a JAX-RS endpoint programmatically?

Question

TomEE 1.7.2, Java EE 6, Java 8

I have this JAX-RS Application:

@ApplicationPath("/api")
public class CallStatsCatcherApplication extends Application {
    @Override
    public Set<Class<?>> getClasses() {
        return new HashSet<Class<?>>(Arrays.asList(RestEndpoint.class));
    }
}

@ApplicationScoped
@Path("/rest")
public class RestEndpoint {
    @GET
    public String echo(@QueryParam("foo") String foo) {
        return foo;
    }
}

During startup, TomEE prints:

INFO:               GET http://localhost:8080/test-application/api/rest/      ->      String echo(String)

How can I get that URL programmatically during startup? I'd like to create a framework that advertises this URL locally on the network.

To get server adress part you can try use something like that: Java EE: how to get the URL of my application?

But if you need IP address in startup bean, you can try use:

InetAddress ip = InetAddress.getLocalHost();
String ipAddress = ip.getHostAddress();`

Another option is to use:

MBeanServer mBeanServer = ManagementFactory.getPlatformMBeanServer()`

But it may be associated with the server platform and you will need to search the property.

Is there anyway to do that _not_ in the request lifecycle though when there is no active HttpRequest? – Jonathan S. Fisher Dec 07 '15 at 23:49
Sweet... that's just a little bit farther... what about the port the server is listening on? – Jonathan S. Fisher Dec 08 '15 at 00:09
The port is not constant? – ostry Dec 08 '15 at 00:12
In production it will be, but for local testing it could definitely be different. – Jonathan S. Fisher Dec 08 '15 at 00:28
Ah crap... also need the context root. Sigh. This is difficult! – Jonathan S. Fisher Dec 08 '15 at 00:41

You can use the UriInfo class in conjunction with UriBuilder class to mount or create URLs using the current path.

There is similar question in stackoverflow: getting the base url...

I saw that class too... the javadoc says it has to be called in the scope of a request, I was hoping to find something for boot time – Jonathan S. Fisher Dec 08 '15 at 00:28
