dbus java bindings name registery and introspection problem

[ozgur cagdas]

Hi,

I have written the below interface and it's implementation just to practice java dbus bindings but the problem is, when I compile it and run, it doesn't register the name 'com.mycompany.wrapper_interface' but a standard name assigned by the bus something like ':1.99'. 

Just probably because my implementation of Introspect method returns null, I cannot introspect this interface either. Previously I've used Qt dbus bindings and in that case using annotations was enough to make the interface introspectable. So, what should I do to make this interface introspectable? I hope the answer is not simply 'fil the Introspect method manually' or at least there is a better alternative do exists.

Cheers,

Ozgur.

ps: I am using dbus-java-2.7

package com.mycompany.wrapper_interface;

import org.freedesktop.dbus.DBusInterface;
import org.freedesktop.dbus.DBusInterfaceName;

import org.freedesktop.DBus.Introspectable;
import org.freedesktop.dbus.exceptions.DBusException;

@DBusInterfaceName("com.mycompany.wrapper_interface.DvbDemuxInterface") //although this shouldn't be necessary since it's same with the package name, using anyway
public interface DvbDemuxInterface extends DBusInterface, Introspectable {

    public class DvbDemuxDbusSigNo1 extends DBusSignal {

        public DvbDemuxDbusSigNo1(String path, String name) throws DBusException {
            super(path, name);
        }
    }

    @org.freedesktop.DBus.Description("Print something for me")

        try {

        int count = 2;
        while(count != 0) {
