Emmanuel Bernard commented on HBX-733:
--------------------------------------
Check the code, Hibernate Annotations has no EJB 3.0 bells and whistles whatever that
means
It certainly do not depends on an App server (for that matter the EJB 3.0 Persistence spec
aka JPA does not either).
As for the EJB 3.0 decorator, are you referring to the annotations? @Entity and so on?
So what is best, having an annotation @org.hibernate.annotations.Table to describe a
table, or having a standard annotation @javax.persistence.Table?
There is no difference, technically, except that you are closer to the standard. Any
drawback? No.
People completely misunderstand EJB 3.0 because they thing that EJB 3.0 == EJB 2.x, this
is not true, read the spec. For that matter, JBoss has an EJB 3.0 container which is
"as lightweight" as Spring Framework, yes it runs in a junit test. yes it runs
in tomcat. Some competitor might have a heavyweight implementation but that is clearly not
inherent to the specification.
FTR, I do believe that EJB 3.0 (the container) combines with Hibernate (and JPA) even
better than Spring.
Check the docs and tutorials :-)
Updated DAO code generation as discussed over the email
-------------------------------------------------------
Key: HBX-733
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HBX-733
Project: Hibernate Tools
Type: Patch
Components: hbm2java, ant
Versions: 3.1alpha5
Environment: I have tested the patch on the latest version of Hibernate Tools I got from
SVN 2 weeks ago.
Reporter: Alex Kalinovsky
Attachments: dao_generation.patch
Original Estimate: 3 days
Remaining: 3 days
This should be a complete implementation of DAO generation according to the design we
have discussed over the email. I've tested this on our project so the DAOs should be
good to go, but of course a more diverse testing would be needed before releasing it to
public. I'm open for recommendations and suggestions, so I see this as the first
draft. Below is a list of files and comments. Contact me at kalinovsky(a)yahoo.com.
src/java/org/hibernate/tool/hbm2x
DAONewExporter.java This class is coded mainly to accept additional parameters
such as dao package name and provide flexible
file naming that is used by Ant task. It would not be needed
if I integrate my changes into GenericExporter.
