An excellent intermediate-level JPA overview. I appreciated the segment concerning specifying meta-data via a "merged view" that split the meta-data between annotations and XML. I found Linskey's information to be very informative and useful.
The video includes some very helpful examples (including JPQL and native queries) that I was able to immediately apply to what I was working on -- one of which I discuss in my next post.

Interesting topics like compound identities and disabling(!) annotations are covered. A lot of what's covered I have not come up against in my normal day-to-day JPA programming, but it is still nice to see what's available to me in case I need it someday.

A good overview of possibilities to come. Personally, I like the sound of built-in validation annotations in JPA. Right now, I'm using Hibernate's validation annotations in my Seam Framework applications and those work fine, but it would be nice to use some standard validation annotations instead.

These looked promising, but the performance is horrible, and I'm on a corporate network with a large pipe to the network. The first video was barely understandable for the first few minutes, and then it froze.
I'm not sure what could be causing problems on their site. I have watched all three videos at least twice each on my cable connection at home and all three played fine.
