Actually I did the same thing from this example: 
http://tuscany.apache.org/workingwithstaticdataobjects.html

Just

SDOUtil.registerStaticTypes(CustomerFactory.class);

was changed with

HelperContext hc = HelperProvider.getDefaultContext();
PersonFactory.INSTANCE.register(hc);

But unfortunately it's not working.
