| Re: [eclipselink-users] MOXy & JPA |
Hello Roger,My recommendation to users is to start with a well designed model and use EclipseLink to map this model to both XML and your database. This will ultimately make your application development easier.
You can also take the model generated by JAXB and annotate it JPA annotations. Since JAXB will generate a class per level of nesting you will probably end up with a larger than desired domain model.
Maintaining seperate jaxb and jpa models and the logic to convert between is a brute force approach and ultimately the hardest to maintain. You end up with multiple models and custom conversion logic. A small change in either the db or schema requires changes to both the generated models (possibly regenerating) and custom conversion logic.
I am currently out of the office. I can send you some examples when I'm back on Monday.

Hi I've just started experimenting with MOXy and I've now managed to get my java classes generated from an .xsd file. It's been a bit hit & miss and I was wondering if there were any good tutorials on setting up a MOXy project within Eclipse. Now that I've got my @Xml annotated Java classes, can I now add JPA annotations to them as well? Assuming that the answer is yes, is it actually a good idea or would I be better to maintain a seperate set of JPA .java files and use one of the Bean libraries to transfer data between them?
