I'll try this out. At runtime, the log4j.dtd file is in the classpath, so I'm not sure whether we can change the system ID, but I will look into how to do this and have it still work with log4j. . John On Feb 16, 2005, at 10:00 AM, oxygen-user-request@oxygenxml.com wrote:

Hello,

The XML parser resolves only full URIs using the catalog so if you specify the system ID with a relative path first it will be expanded to its full path and then searched in the catalog. If the XML document is located in the directory C:\work then you must specify in the catalog:

<system systemId="file:///C:/work/log4j.dtd" uri="file:///Users/john/Documents/oxygen/log4j.dtd"/>

You can make the document portable if you use a system ID like logging.apache.org/site/log4j.dtd in the document and

<system systemId="logging.apache.org/site/log4j.dtd" uri="file:///Users/john/Documents/oxygen/log4j.dtd"/>

in the catalog where the uri attribute is modified by each user to correspond to the path on the local machine.
