All Implemented Interfaces:

Serializable, Servlet, ServletConfig

public class MCRURNResolver
extends MCRServlet

This servlet resolves a given URN (urn:nbn:de) from a HTTP request and redirects the client to the document that is registered for this URN. The URN can be either given as the query string or as the request path. If the URN is assigned to a local document, the request is redirected to the frontpage that displays the document's metadata, as specified by the configuration property MCR.URN.Resolver.DocumentURL. If the URN is not local, the request is redirected to another URN resolver, as specified by the configuration property MCR.URN.Resolver.MasterURL.
