EclipseLink/Development/DBWS/MetadataGenerationFromDDLMetaModel
Generating JAXB and JPA Metadata From DDL Parser Meta-model
The EclipseLink DBWS design time component (a.k.a. DBWSBuilder) generates OR and OX projects for use by the runtime component - these project instances are built using DDLParser generated meta-model objects. Since EclipseLink 2.5, DBWS generates and writes out JAXB and JPA metadata (DBWS Metadata Support) based on the OR/OX projects. When considering JAXB/JPA metadata generation consolidation among various components, it would make sense to have the ability to generate metadata directly from the DDLParser generated metamodel, then bootstrap DBWS builder, JPA-RS, etc. from this metadata. This would allow the DDLParser and metadata generation piece proposed here to be standalone components, available for use by other components.
