[xwiki-users] Obtaining a XWikiContext

Hi, for one of our projects, we're creating a XWiki component, based upon this documentation (http://platform.xwiki.org/xwiki/bin/view/DevGuide/WritingComponents). In documentation, it is said we can access the XWikiContext, which is also said to be deprecated. Considering that, and the fact we're running in XWiki 7.0, what is the best way to get incoming request parameter ? Thanks
