Does anybody have a pointer to what folks should do with their existing J2EE 1.4 code/applications?
What are the migration/evolution best practices?
For example: if I have a J2EE 1.4 ejb-jar and I want to start doing EJB 3.0, what should I do?
a. change the namespace in my existing jar, then rock and roll...
b. create a new jar for my EJB 3.0 components and "call" back and forth between the two jars...
I would imagine that we don't get to mix-and-match @Entity and CMPs...
What other "gotchas" are there?
