Don't put that there. An array isn't a valid serializable object (and putting fields in an interface is an established Bad Thing (tm) according to Josh Bloch, though sometimes handy for cases like this).
Best change that array to 2 separate String fields (I assume they're allowed values for some parameter?).
P.S. there's no need to mark the field public static final in the interface, it's implicit (just as methods in interfaces are implicitly public).
Thank you very much !
This EJB work on WebLogic, but, I want use JBoss now !! I'll test with 2 separate String fields !
So, thank you jwenting.
