如何将序列化对象从Android客户端发送到Google App Engine Servlet？

Question

如何将Android客户端的序列化对象发送到Google App Engine Servlet。
我有这样的代码：

private static HttpClient getHttpClient() 
{ 
if (mHttpClient == null) 
{ 
    mHttpClient = new DefaultHttpClient(); 
    final HttpParams params = mHttpClient.getParams(); 
    HttpConnectionParams.setConnectionTimeout(params, HTTP_TIMEOUT); 
    HttpConnectionParams.setSoTimeout(params, HTTP_TIMEOUT); 
    ConnManagerParams.setTimeout(params, HTTP_TIMEOUT); 
} 
return mHttpClient; 
} 

public static String executeHttpPost(String url, Object obj) throws Exception 
{  
    HttpClient client = getHttpClient(); 
    HttpPost request = new HttpPost(url); 
    request.set(???? 
} 

我如何从这里继续下去吗？
有没有更好的方法？

在这里你去：

ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
ObjectOutput out = new ObjectOutputStream(bos); 
out.writeObject(obj); 
byte[] yourObjectSerialized = bos.toByteArray(); 

HttpClient client = getHttpClient(); 
HttpPost request = new HttpPost(url); 
request.setEntity(new ByteArrayEntity(yourObjectSerialized));
