Just put the string that maps to your servlet in the hyperlink.

Servlet class get method:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Servler example</title>");
out.println("<body>");
out.println("<h1>Package class simple servlet<h1>");
out.println("</body>");
out.println("</html>");
}

prompt.jsp:

Web.xml:

<servlet>
<description></description>
<display-name>hello</display-name>
<servlet-name>hello</servlet-name>
<servlet-class>pack1.hello</servlet-class>

Post the link that you are trying to use to invoke this servlet. You should dynamicaly get your context path and then append your servlet name in your mapping.
