How can I generate JPA2 compliant @Entity from existing Databases?.
I found this: Question
Still its not clear if JBoss will generate compliant JPA2 and also I would like to know if there is a vendor independent way to do this.
You can use a plugin like Eclipse Dali to do the trick for you. You can refer to the documentation, section 3.11 Generating Entities from Tables.
I do not know of any specific vendor independent tool to do this, though.
