Loading Schema Definitions and Generating
Schema Helper Classes 
The WSDL schema fragments are loaded in the internal schema representation. The Schema-to-Java generator is initialized and mapping between schema and Java components is also initialized. If required, schema helper classes are generated to represent the schema types in the Java language.
All schema-derived classes are stored in types sub-package of the root proxy package. If more than one schema is used, then a sub-package of types package is used for each additional schema. ackage mapping of schema types can be configured (by default, additional packages have the names pN, where N is a sequential number).
