Subject Re: Where do I get javax.persistence package?
Date Sat, 27 Oct 2007 17:48:49 GMT
Hi Satsuma...

  I've started mt Java and JEE development using NetBeans - before joining
IBM Egypt - it was really and advanced Java and JEE development tool, but
being slow is a killer point for development. I suggest you use Eclipse or
IntelliJ which most of the team use to develop for OpenEJB3.0 .
