i did a simple Web Service in Java and i deployed it in JBOSS 5.1. This WS handles C2DM service for sending a notify message to an Android phone. I set all like i red in google c2dm api, and, first of all, i sign up for accessing to c2dm service. In this case, all works well.
Now i have to do the same in .NET on IIS7. Some clarification about the .Net code:
setRegId() and pushMessage() method are available by WebService.
handShakeRegId() is simply called by setRegId() after String "reg_id" and "device_id" are setted
all code commented are my try for solving problem, but all was useless
Thats the code:

Error which comes out is always the same in pushMessage getResponse() ( and its strange because i implement connection exactly like its in handshake method :-/ ):
A first chance exception of type 'System.Net.WebException' occurred in System.dll (pushMessageMsgIN) Error: System.Net.WebException: remote server error (401) Unauthorized in System.Net.HttpWebRequest.GetResponse()
2 days for searching something useful but.... NOTHING!! Its very stressful...
I hope someone can help me.
I red something about Authentication in IIS, so i enabled Anonymous User and other unknown things just for trying. Nothing!
Solved: MY STUPIDITY !!! i made a mistake in private String source !! I specified a wrong package name! -.-
