Ugo, can you can share experience with Hibernate vs. Jakarta OJB, Cayenne or another Open Source O/R tool.
There is a reasonably objective comparison here http://c2.com/cgi-bin/wiki?ObjectRelationalToolComparison but I would like to hear more from a usability, flexibility and performance perspective. -=Ivelin=- ----- Original Message ----- From: "Ugo Cei" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, February 15, 2003 2:41 PM Subject: Re: extending XMLForms for different kinds of models...opinions? > Sylvain Wallez wrote: > > This is a good idea when you need to use the JavaBean for some business > > logic.
