EJB3 multiple embedded component safe namingstrategy

[js8523]

Hi Gavin

I am sorry to post this question here, but I know that you were one of the original authors of this section of code!

How do you change the default namingstrategy to the safe version you guys created (which I cannot find)?

I could not find a configuration (persistence.xml or hbm.cfg.xml) method anywhere, and I could not find the location of the safe namingstrategy version that was talked about in some newsgroup discussions.

I could not find any documentation for this, so if you are kind enough to tell me I promise to add a wiki statement in the hibernate pages.

Many thanks for any help.

I've no idea what you're talking about...

Sorry for the confusion

Gavin, I saw your name on the original implementation of the hibernate naming strategy, therefore I thought you were the most appropriate person to ask.

I eventually found the resolution in a mail group email.

you use the following setting in your persistence.xml



This resolves the issue when you have two objects (of type Embeddable) in a entity, and the default naming strategy tries to give a table with two identitical column names.


I hope this helps other people.

Many thanks,

James
