title: Initialize data in the beginning Wicket Application throw url parameters
body: <p>Let's imagine that I have a application which is written in JSF, and I have some module which is written in Wicket. The user authorize in JSF application, and go to Wicket module throw simple link, and transfer username therein. So, the question is, how I can get that url request in Wicket application? I think that in <code>Application</code> class which is extend Wicket <code>WebApplication</code> class using <code>Request</code> class. Am i right? Where I should call that? In constructor or in the init() method?</p>
