Hi Jane, Spring Data JPA is just helping you to implement data access layer easily. You will still have to choose a JPA implementation.
I don't think we can easily use Spring projects with WSO2 Carbon Components. In the past, we have tried to stay away from using Spring framework in our code. You can try using Spring Data JPA. I also have experience using Spring Data JPA and it certainly helps to write code very efficiently and quickly. I'm not sure why you say Apache OpenJPA is buggy. It's an active project and the recently release is on May 5 [1]. It might had many bugs in earlier releases, but I think we can use latest OpenJPA for Stratos requirements. Thanks!
