So for the moment, no dtd reference is possible

// Turn validation on for the DOM parser to make sure it reads the DTD
domParser.setFeature("http://xml.org/sax/features/validation", true);
DTDResolver dtdResolver = new DTDResolver("xbel-1.0.dtd");
domParser.setEntityResolver(dtdResolver);

// Parse the XML document containing the user's bookmarks
domParser.parse(new InputSource(new StringReader(inputXML)));

Here's an example patch that fixes uPortal so it will use the services.dtd when parsing the services.xml file. I've tested this and it works.

thanks,
Brad

Not yet validating.

When I enable validation I got a complaint about PersonDirs.xml not having a DOCTYPE, so I
added/created one. Now I get a NPE because personAttributeDao is invoked
before uPortal has been initialized so there is no way to load the PersonsDir.dtd
with PortalSessionManager.getResourceAsStream()

Any ideas?
