tomcat应用迁移到was出错 servlet获取不到parameter呀 大家帮我看看

j2ee应用部署到tomcat是正常的 但是迁移到was上就报错

功能大概是：
客户端传送xml文件及url参数给服务器端servlet doPost()
错误出现在服务器端servlet的doPost getParameter()

客户端代码如：
……
URL url = new URL("http://192.168.2.65:9080/ex_server/sendzip?actioncode=2&billid=2&checkorg=370100");
URLConnection urlconn = url.openConnection();
urlconn.setDoOutput(true);
……
服务器端代码如：
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

ServletInputStream inputStream = request.getInputStream();

50行------------String checkOrg = request.getParameter("checkorg");
String actionCode = request.getParameter("actioncode");
String billId = request.getParameter("billid");
……

异常如下：
