I have some experience in ejb1.1 and have no idea about ejb2.0. so I want to take the
test on july in order to look through the ejb2.0 spec.
I am wondering if my voucher would be invalid because of some reason (for exampe:adequate testers took the test ,etc.) at that time.
Can anyone give me an advise?
Excuse my poor english.
Thanks in advance!
Sincerely
Sam
