This example walks through the migration from Hibernate(TM) V3 using JPA + native annotations in combination with the native API to EclipseLink JPA.

Entity Annotations

Custom Sequence Generator

In Hibernate a custom generator for sequence values can be defined and used as:

   @Id
   @GeneratedValue(generator = "system-uuid")
   @GenericGenerator(name = "system-uuid", strategy = "mypackage.UUIDGenerator")
   public String getTransactionGuid()

With EclipseLink a custom sequence generator can be implemented and registered for use using the @GeneratedValue. How to use Custom Sequencing (ie. UUID)
