GWT RPC method name at App Engine server log

Question

Hi, our project runs on GWT and Java App Engine and we use the standard GWT RPC mechanism. App engine adds log trace for each RPC call, but it just logs the servlet URL and not the called method. We would like to add the method name to the log URL.

We have tried extending RpcRequestBuilder class, overriding doCreate and adding the method name to the URL, but the problem is that at this point the method name is unknown - it's known later at doSetRequestData (as part of the data string).

Thanks Itzik
