Class BootstrapResolver

java.lang.Object

org.jboss.util.xml.catalog.helpers.BootstrapResolver

All Implemented Interfaces:

javax.xml.transform.URIResolver, org.xml.sax.EntityResolver

public class BootstrapResolver
extends java.lang.Object
implements org.xml.sax.EntityResolver, javax.xml.transform.URIResolver

A simple bootstrapping resolver.

This class is used as the entity resolver when reading XML Catalogs. It searches for the OASIS XML Catalog DTD, Relax NG Grammar and W3C XML Schema as resources (e.g., in the resolver jar file).

If you have your own DTDs or schemas, you can extend this class and set the BootstrapResolver in your CatalogManager.
