I have some code using EJB's. I want to know a couple of simple
answers.
How does one know if EJB v1.0, v2.0, or v3.0 are being used.
Are they backwards compatible?
I read an ariticle which discussed how certain things were made
simpler in v3, but my fundamental question is will old code still
work.
Are EJB's tied to a particular J2EE?
Somewhere I have read that one should use EJB with J2EE1.5.
