python 2.6 请求servlet报错?报错

我的sendToJava.py中的程序如下：

#-*- coding:utf-8 -*-
ps_url = "http://10.143.239.253:8080/secondJavaDemo/TestServlet?account=guopengfei&receiver=0001"
filename="E:\PythonWork\Testdefdoc.xml"
file = open(filename, 'r')
content = file.read()
import urllib2
req = urllib2.Request(url=ps_url,  headers = {'Content-type':'text/xml'})
req.add_data(content)
rep = urllib2.urlopen(req)
print rep.read()

package com.demo;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class TestServlet extends HttpServlet {

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		System.out.println("执行get方阿飞");
    	String  string = req.getParameter("account");
        System.err.println("接收到的数据为："+string);
        resp.setContentType("text/xml;charSet=utf-8");
        
		super.doGet(req, resp);
	}

	@Override
	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
			throws ServletException, IOException {
		System.out.println("执行post方阿飞");
    	String  string = req.getParameter("account");
        System.err.println("接收到的数据为："+string);
		super.doPost(req, resp);
	}

}
