Thanks for your feedback! I'm sorry you feel like this. Please note that the description of the book mentions that basic knowledge of JSF is expected. However, I got very positive feedback from some beginners that used my book to get started.

The tricky thing when getting started is always that there are so much components involved. That often makes it hard to pinpoint the problem if something gets wrong. I'm glad you found a solution to your problem. Please feel free to contact me if you get stuck again!

Best regards,
Bart Kummel

I hope this answers your question. Should you have more ExtVal-related questions, you could also ask them on the MyFaces user list.

I started looking at ExtVal and it offers quite a bit from the standard validation that is included in JSR 303. It all works very nicely. I was wondering if you knew if this can work within the EJB tier via a ValidationFactory.

At this point it appear to only get automatically invoked from within JSF 2.0. I ask because it would be nice to use the same exact validation in the EJB tier if for example an non JSF client (Java SE) calls an EJB.

Thanks
Pete
