Class FacesViewsForwardingFilter

java.lang.Object

org.omnifaces.filter.HttpFilter

org.omnifaces.facesviews.FacesViewsForwardingFilter

All Implemented Interfaces:

Filter

public class FacesViewsForwardingFilter
extends HttpFilter

This filter makes sure extensionless requests arrive at the FacesServlet using an extension on which that Servlet is mapped, and that non-extensionless requests are handled according to a set preference.

A filter like this is needed for extensionless requests, since the FacesServlet does not take into account any other mapping than prefix- and extension (suffix) mapping.

For a guide on FacesViews, please see the package summary.
