Forwarding in custom RequestProcessor
Hi!
I have extended the RequestProcessor's processPreprocess() method
in order to perform a simple user authentication mechanism using
cookies. If a cookie identifying a user is found, but the users member-
ship has expired, I would like him to be forwarded/redirected to a
corresponding error page. What is the best way to do this? I tried
the following:
request.getRequestDispatcher( "membershipExpired.jsp" ).forward( request,
response );
which works fine. But this is surely not how struts should work because
I have hardcoded the target in my code, and not configured in my
struts-config.xml for example. So if the error page changes I have to
chnage my code and not only the struts-config.xml. Does anybody know
a better solution? I tried a global-forward like this but it didn't work:
<global-forwards>
<forward name="nodb" path="/membershipExpired.jsp" />
</global-forwards>
with
request.getRequestDispatcher( "nodb" ).forward( request, response );
Perhaps I made a mistake somewhere...

Have you considered doing this in a Filter instead of extending the
RequestProcessor? I question the wisdom of tying
authentication/authorization so closely to the Struts framework.
With a Filter, you can stick it in front of anything. For example, I posted
all the documentation for our internal projects on the web server, but
didn't want to leave it wide open. Though it's all static HTML, it's
packaged as a .war file, and I was able to drop the same Filter I use in
Struts apps in front of it with a simple change to web.xml.

Calling just request.getRequestProcessor() effectively exits the
Struts environment since the request object doesn't know anything
about struts_config.xml. You need to use the method and fields of the
RequestProcessor instead.
Try this:
ActionForward expireForward = moduleConfig.findForwardConfig("nodb");
processForwardConfig(request,response,expireForward);
return false;

RE: Forwarding in custom RequestProcessor
Posted by "Mulligan, Scott H" <sc...@eds.com>.
I extended the RequestProcessor to forward between two web applications. The following code is what I use to forward to an action that the other web application has. Then the other web application can define an action that can handle forwarding to whatever jsp it wants.
if (forward.getName().startsWith("common_"))
{
getServletContext().getContext("/thinClient/common.do").getRequestDispatcher("/common.do").forward(request,response);
return;
}
