I need some help to integrate the NetworkAddressService to get the primary IP.
Preparation in the Code:
```
import org.eclipse.smarthome.core.net.NetworkAddressService;
Class:
private NetworkAddressService networkAddressService;
Code inside the ThingFactoryClass class (tried also others):
@Reference
protected void setNetworkAddressService(NetworkAddressService networkAddressService) {
this.networkAddressService = networkAddressService;
}
protected void unsetNetworkAddressService(NetworkAddressService networkAddressService) {
this.networkAddressService = null;
}
Usage:
networkAddressService.getPrimaryIpv4HostAddress()
```
Sounds easy, but the problem is that the setNetworkAddressService() is never called. The binding gets loaded, but I reach never the breakpoint I set on the routine.
I checked OSGI-INF/ThingFactory.xml
```
<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="..." activate="activate" configuration-pid="telekomtv" immediate="true" name="org.openhab.binding.telekomtv.internal.TelekomTVHandlerFactory">
<service servicefactory="false">
<provide interface="org.eclipse.smarthome.core.thing.binding.ThingHandlerFactory"/>
<provide interface="org.openhab.binding.telekomtv.internal.TelekomTVHandlerFactory"/>
</service>
<reference bind="setNetworkAddressService" interface="org.eclipse.smarthome.core.net.NetworkAddressService" name="NetworkAddressService" unbind="unsetNetworkAddressService"/>
<implementation class="org.openhab.binding.telekomtv.internal.TelekomTVHandlerFactory"/>
</scr:component>
```
so the @Reference works. Otherwise Eclipse told me that this is not a public interface.
Is it correct that I need to add a rule to the Java Build Path to get access to
I checked out ESH API Reference->NetworkAddressService documentation, but it does not contain no information how integrate the class. Need some help.

Hi Kai, this did the magic. Thanks!!
When I'm going to implement UpnpIOParticipant and add
import org.eclipse.smarthome.io.transport.upnp.UpnpIOParticipant;
import org.eclipse.smarthome.io.transport.upnp.UpnpIOService;
@Override
public void onValueReceived(String variable, String value, String service) {}
Eclipse shows the following error:
Multiple markers at this line
- Illegal redefinition of parameter variable, inherited method from UpnpIOParticipant does not constrain this parameter
- Illegal redefinition of parameter value, inherited method from UpnpIOParticipant does not constrain this parameter
- Illegal redefinition of parameter service, inherited method from UpnpIOParticipant does not constrain this parameter
- implements org.eclipse.smarthome.io.transport.upnp.UpnpIOParticipant.onValueReceived
However, declaration of UpnpIOParticipant contains
/** Called when the UPNP IO service receives a {variable,value} tuple for the given UPNP service **/
public void onValueReceived(String variable, String value, String service);
so exactly like my implementation.
onServiceSubscribed same - Eclipse reports errors on String
whereas onStatusChanged is accepted, because it contains no String parameters.
Any magic hint?
