Subject RE: OPEN-JPA and Toplink 2.0.XX
Date Mon, 26 Mar 2007 00:50:06 GMT
However, note that you may well want to use JPA when using Toplink. Both
Toplink and OpenJPA are implementations of the JPA specification, so you
might choose to write your application to use JPA (javax.persistence.*)
in your code, and then use either OpenJPA or Toplink as implementations
of the interfaces in javax.persistence.
