Two buttons in same Jsp connect to two methods

<![CDATA[<%@page import="com.mobitel.bankdemo.web.GetSession"%>]]>
<![CDATA[<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>]]>

There are so many way to handle this.

Process 1
=============
1. Create a hidden filed in your jsp called as "ReqType" .
2.Set value as per Login/Logout request.
2. Read this value in servlet

String type request.getParameter("ReqType")
if("LOGOUT".equals(type)){
//do logout operation
}else if("LOGIN".equals(type)){
//do login operation
}

Process 2
=============
1. Assume that requested url are
http://localhost:8080/login
http://localhost:8080/logout
2. add both url pattern in you web.xml file to point the same servlet

3.And read the Uri info in servlet

String uri = request.getRequestURI();
if("/login".equals(uri)){
//do login operation
}else if("/logout".equals(uri)){
//do logout operation
}
