Subject Re: Java 1.4 and JEE 5

We're working on a plugin that adds JPA support to web apps (assuming
you started Geronimo in Java 5).  If you can help with the OpenJPA
provider, that would be great.  I think there should be something to
show for this soon.  I'm eagerly awating Jason's fix to the
car-maven-plugin so we can pop a plugin out of a Maven build.  :)

However, it's really only a stopgap measure.  Even to do that much, we
have to work around limitations of the Geronimo deployer (which
doesn't seem to have good handling for letting many deployers all
operate on one module).  So we can fix that in 1.2 or whatever, but
even so, you're right that it would be nice to drop J2SE 1.4 support.

I think the real holdup is CORBA certification.  How's Yoko coming?
Rick, weren't you tracking how close we were to being able to switch
over to it?
