Does not look hopeful

Hi,
Mathematica does not seem to simplify the following expression:
(BesselJ[2, BesselJZero[0, n]] BesselJZero[0, n]^2)/ BesselJ[1,
BesselJZero[0, n]]
(I believe the answer is 2 BesselJZero[0, n]^2)
Is there a way of making Mathematica deal with these types of expressions?
Many thanks in advance,
Sam
