ho to check if forward-target exists?

[Marten Lehmann]

Hello,

I can start a forward like this e.g. through a filter:

request.getRequestDispatcher(/test.html).forward(request, response);

But how can I check if the ressource really exists?

request.getRequestDispatcher(/test.html) always gives me a 
RequestDispatcher reference. Or is it possible to get the response-code 
somehow to check if the forward resulted in a file-not-found error?


Regards
Marten

If you are looking for a physical resource use
if (null==servletContext.getResource()) {
  ... yes it exists ...
}
