Using JSON-RPC with yaws_rpc works perfectly fine for me using "JSON/ 
XML-RPC Client <http://code.google.com/p/json-xml-rpc/>" as client  
library.

However I would like to point out, that JSON-RPC appears to be not  
fully implemented in yaws_rpc regarding the json-rpc error reply.
For example: A perfectly valid json-rpc reply of the form
	{"id":6,"error":{"code":23,"message":"this and that"}}
can not be handled by yaws_rpc, where replies indicating a success  
such as
	{"result":true,"id":2}
are being handled just fine.
