Subject Re: Cayenne vs JPA tools
Date Sun, 25 Feb 2007 15:53:36 GMT
I have taken a look at Hibernate a bit this weekend which claims to be JPA
compliant. I haven't looked at the JPA APIs in much detail yet, but what is
your gut feeling on the migration path between Cayenne 2.x and Cayenne JPA?
We are already going thru a lot of changes to migrate from EOF to Cayenne -
I really don't want to have to radically rebuild our app again when Cayenne
JPA rolls around.

BTW - I don't really care for the manual building of Hibernate mapping
files. It seems like a step backward from Cayenne.

I haven't gone into depth yet on Hibernate - it seems capable but I think
people who have never used tools like EOF or Cayenne really don't appreciate
their sophistication and design.

Are there any comparisons between current versions of Hibernate and Cayenne?

Thanks in advance
