Class XMLCatalogSystemIdAdapter

java.lang.Object
  org.backsource.utils.ant.XMLCatalogSystemIdAdapter

All Implemented Interfaces:

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

public class XMLCatalogSystemIdAdapter

extends java.lang.Object

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

Adapts the ant XMLCatalog, so that it is possible to lookup also systemid.

The current implementation of XMLCatalog only handles public id for dtd:s and enitiys. Often it is necesarry to be able to also look up a systemId at another location than the one specifyed, for example when only SYSTEM is specifyed in an XML file. eq <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">.

by specifying the last part of the systemid in the XMLCatalog data it is possible to lookup a systemid at another location than the one normaly resolved. for example, the following catalog definition would resolv the above SYSTEM to the log4j.jar file. *

 <xmlcatalog id="jbosscatalog">
   <classpath>
     <pathelement location="${lib.dir}/log4j.jar"/>
   </classpath>
   <entity
                   publicId="log4j.dtd"
                   location="org/apache/log4j/xml/log4j.dtd"/>
 
  </xmlcatalog>
 

Remember that this class is only possible to use from custom ant targets/helper classes.
