Here is my index.jsp code:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Index JSP File</title>
</head>
<body>
<form action="/IndexController" method="get">
<table>
<tr><td>Enter Your Name :</td> <td><input type="text" name="name"/></td></tr>
<tr><td><input type="submit" value="Submit" /></td></tr>
</table>
</form>

Here is my IndexController Servlet code:

public class IndexController extends HttpServlet {

    protected void doProcess(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String uname = request.getParameter("name");
        response.sendRedirect("welcome.jsp?name="+uname);
    }

    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doProcess(request, response);
    }


    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doProcess(request, response);
    }

}

Here is my welcome.jsp page code

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<% String fname = request.getParameter("uname");%>
<h1>Welcome to JSP World,  <%=fname%></h1>
</body>
</html>

When I run this through the Java EE runtime, I got an index.jsp page, but after I entered a name and click submit I got the following error:

Error 404 - Not Found No context on this server matched or handled this request. Contexts known to this server are:  JSPExample(/JSPExample)

    Also change the line in welcome.jsp <% String fname = request.getParameter("**uname**");%> to <% String fname = request.getParameter("**name**");%>, since your parameter name is name response.sendRedirect("**welcome.jsp?name="+uname);** 🙂
