| The _Request_ and _Response_ classes are located in package _org.apache.wicket.request_ and they provide an abstraction of the concrete request and response used by our web application. |
| Both classes are declared as abstract but if our application class inherits from _WebApplication_ it will use their sub classes _ServletWebRequest_ and _ServletWebResponse_, both of them located inside the package _org.apache.wicket.protocol.http.servlet.ServletWebRequest_ and _ServletWebResponse_ wrap respectively a _HttpServletRequest_ and a _HttpServletResponse_ object. If we need to access these low-level objects, we can call _Request_'s method _getContainerRequest()_ and _Response_'s method _getContainerResponse()_. |
