 I use following code:

Wavelet wavelet = fetchWavelet(new WaveId("googlewave.com", waveId),
new WaveletId("googlewave.com", waveletId), url);

where url="http://gmodules.com/api/rpc";;

In log i can see this request JSON:

com.google.wave.api.AbstractRobot makeRpc: JSON request to be sent:
[{"method":"wave.robot.fetchWave","id":"op1","params":
