public class P13NEntityResolver

extends java.lang.Object

implements org.xml.sax.EntityResolver

A SAX EntityResolver which can get XML Entities (including DTDs) for WLCS.

This first looks for a file of the SYSTEM ID, relative to the basePath (either specified in the constructor or defaults to the value of the "commerce.xml.entity.basePath" property in the weblogicommerce.properties file, which defaults to "lib/dtd"). If that fails, it pulls the filename portion of the SYSTEM ID and tries that relative to the same basePath. Failing that, it looks in the CLASSPATH for the SYSTEM ID, relative to the basePath. Failing that, it looks in the CLASSPATH for the SYSTEM ID. Failing that, it looks in the CLASSPATH for the filename of the SYSTEM ID, relative to the basePath. Failing that, it looks in the CLASSPATH for filename of SYSTEM ID.
