does WIcketFilter process subclasses of HttpServlet ?

IN the API for WicketFIlter, we read:
"The advantage of a filter is that, unlike a servlet, it can choose not to process the request and let whatever is next in chain try. So when using a Wicket filter and a request comes in for foo.gif the filter can choose not to process it because it knows it is not a wicket-related request. Since the filter didn't process it, it falls on to the application server to try, and then it works."

I have adopted Wicket recently to upgrade an old application where most of the classes are still subclasses of HttpServlet.
I think the wicket filter does not process classes that extend HttpServlet, but only those that extend Wicket WebPage, etc.



Could anyone confirm ?

Filters do not process classes, they process requests to URLs. Which ones those are depends on how they are mapped in the web.xml file.

"This filter can be used to make the Wicket WebSession instances available to non-wicket servlets. "

I agree. Here's the link: http://aspose.com/file-tools
