A simple way that I use do go:
Super Action class, like:
UserMustBeLoggedAction{
execute(attribs){
verify session stuff....
if ok -> myExecute(attribs);
else return ActionForward;
}
abstract myExecute(attribs);
}
NewAction extends UserMustBeLoggedAction{
myExecute(){
......
}
}
What do experts recommend??
Regards
Felipe

Assunto: RE: Subclassing ActionServlet
Hi
I have come across a plug-in for Struts, that is called as SAIF (Struts
Action Invocation Framework), which enables us to write a pre-action and
post action methods. You can use PreAction method for doing all the
session authentication, etc., I did not really use this, but the
features are available at : http://struts.sourceforge.net/saif/
<http://struts.sourceforge.net/saif/>
Any thoughts on this.
Regards,
Gopal

Subject: Subclassing ActionServlet
All,
I need to check the Session for an authenticated user before
most requests.
To do this I subclassed ActionServlet and only call
super(request, response)
upon verification that authenticated user is in the Session.
if (request.getRequestURI().endsWith("welcome.do") |
request.getRequestURI().endsWith("logon.do") |
request.getRequestURI().endsWith("html"))
{
super.process(request, response);
}
else if (request.getSession().getAttribute("USER") == null)
{
//Forward to login page
response.sendRedirect("/welcome.do");
}
I also know about the ability to subclass the RequestProcessor
and
providing my own implementation of the processPreprocess method
to
accomplish the same thing.
Does anybody know of any serious disadvantages or side effects
of
subclassing the ActionServlet class rather than the
RequestProcessor class.
