Hi All,
I would like to know which is the best approach for session tracking in
struts among the following
1) Writing your own ActionServlet class which will have the
following code
public class MyActionServlet extends ActionServlet{
/* (non-Javadoc)
* @see
org.apache.struts.action.ActionServlet#doGet(javax.servlet.http.HttpServ
letRequest, javax.servlet.http.HttpServletResponse)
*/
public void doGet(HttpServletRequest request,
HttpServletResponse response) throws IOException, ServletException {
System.out.println(" Inside doGet Method of
MyActionServlet");
String id = request.getRequestedSessionId();
System.out.println(" The REQUEST SESSION ID IS
::"+id);
HttpSession session=request.getSession(true);
System.out.println(" Value of the new SESSION
OBJECT IS :;"+session.getId());
System.out.println(" Is it a new session object
? :;"+session.isNew());
if (!(id.matches(session.getId())))
{
System.out.println("************************************");
System.out.println("*********SESSION TIME
OUT********");
System.out.println("************************************");
}
super.doGet(request,response);
}
2) Writing a base action and checking for session expiry in
that class
public class DisplayProfileAction extends Action
{
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws IOException,
ServletException
{
HttpSession session= HttpSession
session=request.getSession(true);
Boolean valid=session.getParameter("VALID");
if (valid == null)
{
System.out.println("************************************");
System.out.println("*********SESSION TIME
OUT********");
System.out.println("************************************");
}
}
}
3) Or using the following code. Any suggestion as to where should
this code be placed. In your own action servlet class or in BaseAction
class
if (!request.isRequestedSessionIdValid())
{
System.out.println("************************************");
System.out.println("*********SESSION TIME OUT ********");
System.out.println("************************************");
}
4) Using filters (Cookies) to track session timeout which by using
filters will the performance of the system not get affected?
Thanks & Regards
