I'm also trying to forward to a JSP from a servlet.
I had planed on having the user log into a standard html page
that would send off a post request to a login servlet which would
then foward to a JSP page. But i keep getting a
-----------------------------------------
Error: 405
HTTP method POST is not supported by this URL
-----------------------------------------
thrown. The JSP that i'm forwarding to is really basic
"Hello i'm hear". From the error message i'm getting i'm thinking
i might need some kind of POST handling in the JSP i'm forwading
to but don't know what that might be (That or the error message is just
a red herring).
I've also attached the code (below) in my doPost Method in my login Servlet.
Any help would be grrrreatly appreciated.
Thanks in advance.
Kelsey.
=======================================
public void doPost(HttpServletRequest request, HttpServletResponse res)
throws IOException, ServletException
{
//Just getting info from the post call
String msgBoxNum = request.getParameter(MSGBOX_NUM);
String msgBoxPin = request.getParameter(MSGBOX_PIN);
//forward to msg box JSP
try {
RequestDispatcher dispatcher =
getServletConfig().getServletContext().getRequestDispatcher("/jsp/jsptoserv/
hello.jsp");
if (dispatcher == null){
PrintWriter out = res.getWriter ();
res.setContentType("text/html");
out.println("Could not forward to msgbox.jsp page. URI
error.");
}
dispatcher.forward(request, res);
}
catch (ServletException ex) { ex.printStackTrace (); }
