Question

in a controller servlet I have the doGet as

protected void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {
  RequestDispatcher view = req.getRequestDispatcher("views/insert_item.jsp");
  view.forward(req, res);
}

in the view insert_item.jsp I want to post back to the same calling servlet but in the HTML Form of the insert_item.jsp I want to specify the Action programmatically such as

<form method="post" action="<%= request.GET_CALLING_SERVLET%>">

I’ve tried

<form method="post" action="<%= request.getServletPath() %>">
<form method="post" action="<%=request.getRequestURI %>">

but these just put the path to the view views/insert_item.jsp

Is it possible to programmatically put the calling servlet into the action of an HTML Form??
Or am I once again trying some unorthodix approach?

Answer 1

You can always pass the original request in an attribute.

But a simpler way would be to use an empty action attribute (html).

<form method="post" action="">
