Jawad, You're right that the first problem was because the types were not defined/registered.
The XSDHelper.define() method is used to define types that will be implemented using dynamic SDO. If, you want to use static (generated) SDO classes, then you must call the generated Factory.register() method, instead of XSDHelper.define() to define the types. Frank.
