how to get HttpServletRequest in My Application class
Hi,
I need to get the HttpServletRequest object in My Application class. In the
WebPage we can get from
((HttpServletRequest) ((ServletWebRequest)
getRequest()).getContainerRequest())
but its not working in Application class. Please suggest any ideas.

I'm new to Wicket, but it seems obvious that this is impossible.
The application object exists outside of resp. independent of any
servlet requests. Only Web pages and their components are
concercened with HTTP requests, and thus only they have access.
If you want to store or access something from a request in your
application object -- which is a singleton that's independent from
any request and any session, then there's probably something wrong
with your design.

BTW, if you get a NPE on RequestCycle.get() then you most likely place this
code outside a Wicket Component like a Page.
Try moving it to a page first and see if you grab a reference to the request
object. If you do, then pass it as a parameter to your other method/class.
For older version of Wicket < 1.5.x see:

For newer version see:
