Hi All,
Just wanted to give you an update on the plug-in work I've been doing.
I've added another patch to OPENEJB-674 (many thanks to whoever applied
the last patch. I've also attached a zip to the issue as I'm not sure if
files I added made it into SVN last time.
With this patch, I think the plug-in will now generate most of the
annotations for session and message driven beans. I'm hoping to use the
plug-in to migrate the code at work (which doesn't have any entity
beans) over to EJB 3 over the next week or so. I'll post with how I get on.
I've added some PDE tests, although I'm not completely sure how to get
them to run from Maven, does anyone know how to do this?
I've also started working on generating annotations for Entity beans.
The approach I've taken is to use the CmpJpaConversion class to get
EntityMappings from both the ejb-jar.xml and openejb-jar.xml and using
the EntityMappings structure to work out which annotations should be
added to the entity bean classes. If I've understood it correctly, when
an EJB 2 app is deployed, OpenEJB generates an intermediate orm.xml file
that it passes to OpenJPA to handle the persistence, so I'm trying to do
the same thing. Obviously, please let me know if you think I'm going
about this the wrong way, or if I could be doing something better.
In terms of CMP beans, I guess we need to convert the CMP class into a
regular class, I was thinking of just removing the abstract keyword, and
turning them into very basic POJOs. I guess we'll also need to find some
way of refactoring lookups to CMP beans to use the JPA EntityManager.
Does anyone have any thoughts on this?
Sorry this has taken longer than I had hoped, I've been pretty busy with
work lately.
Cheers
Jon
