The "Hello" message is a special part of the protocol handshake; I
don't think it's permitted to call it after a connection has been
established.  At least this program fails:
python -c "import dbus;
'/org/freedesktop/DBus'); print dbus.Interface(bus,

There are a lot of variables here; I can't claim to know dbus-java,
ARM, or JamVM (though the latter looks pretty interesting).  Do you
know if for example dbus-java works with JamVM on x86?

Is the problem possibly specific to something on the GSM service
interface?  What if you try to call something simple like ListNames on
the bus?
