Question

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    response.getWriter().append("Served at: ").append(request.getRequestURL());
    System.out.println("Received Value: "+request.getRequestURL());
    Utils.getDataFromFeedbackLink(request.getContextPath());        
    response.setContentType("text/html"); 
    PrintWriter pw=response.getWriter();      
    pw.println("<html><body>");  
    pw.println("Welcome to servlet"+request.getRequestURL());  
    pw.println("</body></html>");   
    pw.close();  

}

web.xml

 <servlet>
    <servlet-name>SubmitFeedbackServlet</servlet-name>
    <display-name>SubmitFeedbackServlet</display-name>
    <description></description>
    <servlet-class>com.techjini.tfs.servlets.SubmitFeedbackServlet</servlet-class>

It's incredible easy: you must use getRequestURL from HttpServletRequest in your Servlet in doGet method

or for more info you can use this methods: getServletPath(), getContextPath and etc.

read more in specification: https://docs.oracle.com/cd/E17802_01/products/products/servlet/2.5/docs/servlet-2_5-mr2/javax/servlet/http/HttpServletRequestWrapper.html#getRequestURL()
