http://xml.apache.org/xalan-j/apidocs/org/xml/sax/EntityResolver.html has
an example similar to what you want to do.
In the class that implements EntityResolver (your DTDResolver), you want
the method
public InputSource resolveEntity (String publicId, String systemId)
{
if (systemId.equals("myDTD.dtd")) {
// return a special input source
return (new URL("http://myserver.com/dtd/myDTD.dtd";
)).openStream();
} else {
// use the default behaviour
return null;
}
}
