從GCM服務器嚮應用程序發送消息

我嘗試從http://developer.android.com/guide/google/gcm/gs.html 執行gcm我可以發送regid到servlet，但無法從它獲取消息。從GCM服務器嚮應用程序發送消息

的Servlet：

if("send".equals(id)) 
     { 
      deviceHolder.put(did, reGid); 
      reGid = deviceHolder.get(did); 
      if(reGid== null || "".equals(reGid)){ 
       System.out.println("device is not registered "+did); 
      }else{ 
       Sender sender = new Sender(myApiKey); 
       Message message = new Message.Builder() 
       .collapseKey("1") 
       .timeToLive(3) 
       .delayWhileIdle(true) 
       .addData("message", "message is created at builder") 
       .build(); 

       Result result = sender.send(message, reGid, 5); 
       System.out.println("result of message is "+ result); 
      } 
     }

GCMINtentService：

@Override 
protected void onMessage(Context arg0, Intent arg1) { 
Log.i(TAG, "new message= "); 
Toast.makeText(getApplicationContext(), arg1.getStringExtra("message"), 
Toast.LENGTH_SHORT).show(); 
}

我怎樣才能解決這個問題？

您的servlet類路徑應包含GCM服務器API。確保你的servlet war文件中的WEB-INF/lib文件夾下有gcm-server.jar。
