I don't konw exactly, but in my "very short experience" (3 months with JavaEE), both are good.
The impact of changing for one to another is mininum if you only uses "standard JPA". But, if you use some special "function" or "feature" from Hibernate (or OpenJPA) the difference will be big. A little example would be sufficient: OpenJPA provides GeneratorType.AUTO, GeneratorType.IDENTITY, GeneratorType.TABLE and GeneratorType.SEQUENCE because are "standard" in JPA, also provides org.apache.openjpa.persistence.Generator.uuid-string, org.apache.openjpa.persistence.Generator.uuid-string, org.apache.openjpa.persistence.Generator.uuid-hex, org.apache.openjpa.persistence.Generator.uuid-type4-string and org.apache.openjpa.persistence.Generator.uuid-type4-hex that aren't "standard" in JPA. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Java EE (J2EE) Programming with Passion!" group.
