  • 0

i’ve created a project in struts2 MVC.
can anyone tell me how to access the servlet without directing through struts2.xml?
i know that we can access through struts2.xml by the action dispatcher but i want to know if there is any other method by which i can access the servlet directly from jsp?

web.xml

MyServlet.java

package com.myservlet;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.swing.JOptionPane;

public class MyServlet extends HttpServlet {
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
        } finally { 
            out.close();
        }
    } 
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);

    } 

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
        PrintWriter out = response.getWriter();
        String name=request.getParameter("username");
        JOptionPane.showMessageDialog(null,"SEEE:"+name);
    }

    @Override
    public String getServletInfo() {
        return "Short description";
    }// </editor-fold>

}

index.jsp

<%@page contentType="text/html" pageEncoding="UTF-8"%>

        <title>JSP Page</title>
    </head>
    <body>
        <form action="MyServlet" method="post">
            USERNAME:<input type="text" name="username"/><br>
            <input type="submit" value="SHOW"/>
        </form>
    </body>
</html>

In the above code why i can’t access the values of the textfield in the getPost() method?
Thanks in Advance…

    I am sure you know about how to call servlet and how to configure them, so i will not go to that detail.

    You can create servlet and can call them as per your use-case all you need to tell Struts2 filter that you do not want some particular URLs to be handled by Struts2

    in your struts.xml add:

    <constant name="struts.action.excludePattern" value="/ServletToExcludeFromStruts*"/>

    For more details refer to webxml
