Class WebFacetsFilter

java.lang.Object
  net.sourceforge.jfacets.web.WebFacetsFilter

All Implemented Interfaces:

javax.servlet.Filter

public class WebFacetsFilter
extends java.lang.Object
implements javax.servlet.Filter

Intercepts HTTP requests and associates a jFacets bean to them. This filter is used to inject the web stuff (request, response and servlet context) into tje system for each request, so that we can have web-enabled contexts in facets.
It loads descriptors at init, and then provides one new instance of JFacets for each request.
