It may be something obvious to DBus as I am new to it. I have seen some posts from Matthew Johnson in the past which were quite useful, but 'FrzRemoteSignal' is in a package. When trying to add a SigHandler for a DBusSignal I am getting the following exception: type.getName: org.freedesktop.DBus type.getSimpleName: DBus 0 [main] ERROR Broadcast - Error: Member name 'FrzRemoteSignal$Sig' is invalid--> [ org.freedesktop.dbus.exceptions.DBusException ] Member name 'FrzRemoteSignal$Sig' is invalid --> org.freedesktop.dbus.exceptions.DBusException: Member name 'FrzRemoteSignal$Sig' is invalid at org.freedesktop.dbus.DBusConnection.addSigHandler(Unknown Source) at org.freedesktop.dbus.AbstractConnection.addSigHandler(Unknown Source) at framez.io.dbus.FrzDBusDrv.startFrzSigListen(FrzDBusDrv.java:96) at framez.io.dbus.FrzDBusDrv.connect(FrzDBusDrv.java:70) at DBusBroadcastSigTest.initApp(DBusBroadcastSigTest.java:96) at framez.core.controller.FrzControllerExec.main(FrzControllerExec.java:104) What I find weird is that the Member name is being called FrzRemoteSignal$Sig - where as DBus's own information does not have this dollar sign: [.()] Handling incoming signal: DBusSignal(1,3) { Signature=>s, Sender=>org.freedesktop.DBus, Destination=>:1.201, Member=>NameAcquired, Interface=>org.freedesktop.DBus, Path=>/org/freedesktop/DBus } { framez.tests.dbus.broadcast } I have ran across a bug in GNU Classpath 0.98 (which is patched now) for Class.getName and Class.getSimpleName - where both of these were being reported as the same. This bug is patched but wonder if this could be another problem like that... As above, using the dbus-java-debug libraries...
