Servlet - doGet - doPost - parameter

Hi,
I have a jsp page (test.jsp), two servlets (Servlet1 and Servlet2).
In test.jsp, parameters are submitted using a form and test.jsp calls Servlet1's doPost method.
Then, in Servlet1, I use response.sendRedirect("/Servlet2") or getServletContext.getRequestDispatcher("/Servlet2") to call the second servlet.
My problems are: (1) Servlet1 always called the doGet method of Servlet2, I want Servlet1 to call the doPost method of Servlet2. (2) The parameters sent from test.jsp are not passed from Servlet1 to Servlet2.
Can someone help?


Thanks,<br />Mike

Hi Mike,
doGet() method is called by default when the form's method attribute is not explicitly set. You must use requestdispatcher.forward("/servlet")to call the next servlet in chain. Then the doPost() method will be invoked and request parameters will be available to the servlet.

to Lakshmi:
I viewed j2ee api doc,but I cannt find you have posted method,"requestdispather.forward("/servlet")"
In apis,requestdispather's method as follows:
public void forward(ServletRequest request,
ServletResponse response)
throws ServletException,
java.io.IOException
would u like explain for me?


Thanks...qingwu<br />When I open my eyes,I see your pretty face.

hi wang ,
U r right. That was a syntax error. It should be as follows:
getServletContext().getRequestDispatcher("/NextServlet").forward(request,response);
Thanks for the correction
