"Hibernate, is prompting interest in transparent persistence. It's a strong solution for medium-sized and smaller applications, especially when the database schema is directly under the control of the development team. Still, many larger customers will not consider an open source alternative, especially a nonstandard one, and Hibernate does not yet have the enterprise extensions or mapping flexibility of the best Java Data Object (JDO) solutions."

Did anyone else see this? I can't think of anymore mapping options provided by the JDO vendors. Perhaps a class to more than 1 table? Is that what he's talking about?

I saw this, and have no idea what Bruce is referring to. The only JDO implementation I ever did a somewhat thorough functional evaluation of was pretty much a subset of Hibernate. I would say that Bruce is probably misled on this point. (Note that I am on the JDO spec group, and Bruce is not, so I consider myself fairly well-informed about the capabilities of both JDO and Hibernate.)

Certainly he does not name any feature that is missing.



If so, he is out of date, since I already implemented this in v22branch ;) This is not really such a good feature anyway, and will come with a "don't use this unless you have to" warning.

"enterprise extensions" sounds like marketing dribble to me.

This kind of guys get me nervious!!! Can he talk about REAL things under his knowledge instead of lying for (i suppose) commercial purpose? arghh he reminds me some people inside my society!!! grrrr[/quote]

Actually lot's of customers are moving to OS just because of good people inside believing and understanding what such tools can provide. No doubt this kind of speak will be outdated some day.

i know about this because i fought to use hibernate... we only want to do our job
