Hi Michael,
yes it is possible, but you need to install the SAXParserFactory as a
service
before starting the registry bundle - I don't know if there's a small bundle
in
Equinox that will do this for you, but otherwise you could write one
yourself.
you just need to do the following in the start method:
bundleContext.registerService(
javax.xml.parsers.SAXParserFactory.class.getName(),
javax.xml.parsers.SAXParserFactory.newInstance(), null);
once this is in place you should be able to use the registry as normal.

I tried the same configuration with bundles from release 3.4.2.
