Hi Frank:
Thanks for the quick response.  My problem was that I was doing a new on
the generated factory, not using the singleton pattern implemented by

You can take a look at SimpleStaticTestCase in the tools-test project
a simple example:


The first thing that you need to do is make sure the metadata is 
registered. Your generated factory class has a register method that you 
need to call:

    scope = SDOUtil.createHelperContext();

Once you've registered the metada, you can load an instance using the 
standard SDO load API: XMLHelper.load().

    XMLDocument xml = scope.getXMLHelper().load(source, null, null);
    assertTrue("Root element is not an instance of the generated class",

        .getRootObject() instanceof Quote);

I hope this helps.
