As David suggests, the best way to get ongoing help is on the OpenAz maillist, which you can browse or join @: http://lists.openliberty.org/mailman/listinfo/openaz
Briefly, there are a few places in the code base that use AzServiceFactory. Probably the best one at present is in the TestUtils module method setupAzService, which is used in most of the testing on the site: http://sourceforge.net/p/openaz/code/HEAD/tree/trunk/openaz/test/src/test/TestUtils.java
In that module, lines 171->203 are a few examples of usage of AzServiceFactory.registerProvider()
