android客户端与服务器servlet通信的一个有关问题，求解惑。

TextView t=(TextView)Select.this.findViewById(R.id.textView00);        String strResult;        String uriAPI="http://10.255.153.46:8080/GetInfor/servlet";        HttpPost httpPostRequest=new HttpPost(uriAPI);        List<NameValuePair> httpParams = new ArrayList<NameValuePair>();        httpParams.add((NameValuePair) new BasicNameValuePair("information", s));    //设置post参数        try {            httpPostRequest.setEntity(new UrlEncodedFormEntity(httpParams,HTTP.UTF_8));            HttpResponse httpResponse = new DefaultHttpClient().execute(httpPostRequest);            Log.d("Infor", "post:"+httpResponse.getStatusLine().getStatusCode());            if(httpResponse.getStatusLine().getStatusCode()==200){        //连接成功                String result = EntityUtils.toString(httpResponse.getEntity());    //获得资源                result = result.replaceAll("\r\n|\n\r|\r|\n", "");                                    t.setText(result);                                                                }        } catch (Exception e) {                                        //捕获并打印异常                    //获得EditText对象            t.setText("连接出错:"+e.getMessage());                                    }

public void doGet(HttpServletRequest request, HttpServletResponse response)            throws ServletException, IOException {        response.setContentType("text/html");        PrintWriter out = response.getWriter();        out.print("ziyanguang:"+out);        out.flush();        out.close();    }
