Enclosing class:

WebContainerAuthorizer

public class WebContainerAuthorizer.LocalEntityResolver
extends java.lang.Object
implements org.xml.sax.EntityResolver

XML entity resolver that redirects resolution requests by JDOM, JAXP and other XML parsers to locally-cached copies of the resources. Local resources are stored in the WEB-INF/dtd directory.

For example, Sun Microsystem's DTD for the webapp 2.3 specification is normally kept at http://java.sun.com/dtd/web-app_2_3.dtd. The local copy is stored at WEB-INF/dtd/web-app_2_3.dtd.
