Bootstrap DBWSBuilder from XMLEntityMappings
DBWSBuilder currently builds an EclipseLink object relational (OR) project from the DDL meta-model returned from the DDLParser. This project is then used to build the various files (XSD, WSDL, etc) required for the web service. This processing is complex and hard to maintain. JPAMetadataGenerator (Metadata Generation from DDL meta-model) can generate and XMLEntityMappings instance from the DDL meta-model; the XMLEntityMappings instance contains an OR project, and DBWSBuilder should be bootstrapped from this as opposed to creating the project.
