error while trying to get connection

[sami Mohammed]

Hello All,

I am a beginner to DBus

Here is my code I am trying to execute and I am getting error

@SuppressWarnings("rawtypes")
public class Client implements DBusSigHandler {

	public void handle(DBusSignal s) {
		if(s instanceof ProximitySignal.Connect)
			System.out.println("Got a connect for "+((ProximitySignal.Connect)
s).address);
		else if(s instanceof ProximitySignal.Disconnect)
			System.out.println("Got a disconnect fo
"+((ProximitySignal.Disconnect) s).address);
	}
	@SuppressWarnings("unchecked")
	public static void main(String[] args){
		System.out.println("Creating Connection");
		DBusConnection conn = null;
		
		try{
			conn = DBusConnection.getConnection(DBusConnection.SYSTEM);
		}catch(DBusException dbe){
			System.out.println("cannot make connection");
			System.exit(1);
		}
		
		try{
			conn.addSigHandler(ProximitySignal.Connect.class, new Client());
			conn.addSigHandler(ProximitySignal.Disconnect.class, new Client());
		}catch(DBusException dbe){
			conn.disconnect();
			System.exit(1);
		}
	}
	
}


Here are the errors

Exception in thread "main" java.lang.UnsatisfiedLinkError: no
