Project overview

This feature is about adding the attribute mapping converter annotations supported by the EclipseLink JPA extension.

  • Provide the validation for the converters

EclipseLink converters documentation

Requirements / Functionality


  • @Convert annotation supported on Basic, Id, Version, BasicMap and BasicCollection mappings
  • Converter, TypeConverter, ObjectTypeConverter, StructConverter will be supported on Id, Version, Basic, BasicMap, BasicCollection mappings in java. In the eclipselink-orm.xml only the convert name widget will be supported on these mappings.
  • Should change non-eclipselink mappings to handle converters with checkboxes: No Converter, Lob, Temporal, Enumerated



  • Converter, TypeConverter, ObjectTypeConverter, StructConverter supported on Entity, MappedSuperclass, Embeddable in java and in eclipselink-orm.xml. Also supported on entity-mappings element in eclipselink-orm.xml.
  • On the eclipselink-orm.xml entity-mappings node supporting adding/removing conerters. If you select a particular converter in the list then you will see that panel for that converter type. This should also be how the support works for Entity, MappedSuperclass, and Embeddable in eclipselink-orm.xml
