postmethod does not work

[Xiaohang Wang <xx...@health.state.ny.us>]

Hello,

I have a problem when the HttpClient try to post some simple form data to
an external Servlet.

The form data comes from this simple jsp:


////// ***** index.jsp  ***** //////////////////////////
<form method="POST" action="PreSend">
<input type="hidden" name="year" value="2007">
<input type="hidden" name="sex" value="male">
<input type="submit" value="Submit" name="submit">
</form>
//////////////////////////////////////////////////////



And the PreSend servlet deals with the request without any problem:


      //////////// ***** PreSend.java  *****
//////////////////////////////////////////////////
          webpage="http://m168.com/test_servlet";
          HttpClient client = new HttpClient();
          PostMethod httppost = new PostMethod(webpage);

          ServletInputStream sis=  request.getInputStream(); ///these 2
line can be replaced by set RequestEntity***
          httppost.setRequestBody(sis); // *** ****************************

          client.executeMethod(httppost);

        ////// *****  or use new api in version 3.1:  *****/////////
        //InputStreamRequestEntity re= new InputStreamRequestEntity(sis);
        //httppost.setRequestEntity(re);

///////////////////////////////////////////////////////////////////////////////////////



However, after the PreSend servlet POST the request to test_servlet,
test_servlet just cannot get any data from its request object.


      //////////// ***** test_servlet.java  *****
//////////////////////////////////////////////////
            Enumeration em=request.getParameterNames();
            String paramName="";
             while(em.hasMoreElements())
            paramName = (String)em.nextElement();

///////////////////////////////////////////////////////////////////////////////////////

   I mean, after control goes to test_servlet, the above paramName is
always empty.


Please give me a hint about what is wrong here.
Thanks for you help!
