RE: RESEND: Is it possible to send control back to 'ActionServlet' instead of to a JSP?

[Kevin Duffey <kd...@buymedia.com>]

I would do it this way..if you want ALL links/pages to go through the
ActionServlet no matter what:

<action path="/Default" class="com.company.actions.Default" />

<action path="/Login" class="com.company.actions.Login">
  <forward name="LoginOK" path="/Default.do?page=somepage.jsp"
redirect="false" />
  <forward name="LoginError" path="/Default.do?page=anotherpage.jsp"
redirect="false" />
</action>

This way, the Default.java class will get ALL links passed to it. The
request attribute "page" would indicate the page to forward to. So..ALL of
your links would be processed by this Default class. Name it what you like.
Then you could wrap up any security issues inside the Default class..such as
making sure if a given path exists in the requestURI, and a certain session
variable doesn't exist..you redirect them to a login page.  I am not doing
this myself mainly because I include the same one header file in every JSP
page that I use some scriplet code to do this. It is a good idea though..the
only problem I see is its a little extra processing to forward to another
servlet to handle the forwarding to a page. Its much faster than
sendRedirect() though..so I don't think its that bad for the extra "control"
you get.
