I was asked to migrate a range of applications to different frameworks.

One of the changes was that JDBC had to be replaced with JPA.

In theory this should be a cinch, but in practice it was very hard. For a range of reasons. Not all of them technical.

In this talk I:

• Show why you ‘should’ migrate to JPA.
• Give an introduction to JPA.
• Show why it is a good idea to use JPA instead of an implementation.
  (Hibernate, openJPA, EclipseLink, …)
• Share the problems we encountered.
  And what you could do to circumvent them.
• Give tips on how to improve code quality.
• Share where to think about with Unit Testing.
