new to HttpClient, how to get serialized objected using HttpClient

[Ashish Kulkarni]

Hi
I am doing following to seralize and send my response in my servlet,
ObjectOutputStream outputToApplet;
outputToApplet = new ObjectOutputStream(response.getOutputStream());
outputToApplet.writeObject(data);
outputToApplet.flush();
outputToApplet.close();

How do i get this seralized object data using HttpClient, i need to get this
Object passed from the servlet,

My Code is as below
HttpClient client = new HttpClient();
        PostMethod postMethod = new PostMethod(url);

         NameValuePair[] data = {
                    new NameValuePair("as400Name", as400Name),
                    new NameValuePair("envName", envName),
                    new NameValuePair("fileName", fileName)
                  };

         postMethod.setRequestBody(data);

         postMethod.getParams().setParameter(HttpMethodParams.RETRY_HANDLER,

                new DefaultHttpMethodRetryHandler(3, false));
int statusCode = client.executeMethod(postMethod);

              if (statusCode != HttpStatus.SC_OK) {
                System.err.println("Method failed: " +
postMethod.getStatusLine());
              }

              // Read the response body.
              byte[] responseBody = postMethod.getResponseBody();
