FoourierTransform of a function defined in sections

Hello,

I want Mathematica to calculate the FourierTransform of a function which is
defined by Sin[x]^2 for Abs[x]<PI and zero else. I tried and defined the
function g as follows:

g[x_]:=If[Abs[x]>PI,0,Sin[x]^2];

That works fine. But if I have mathematica try to determine the
FourierTransform by

FourierTransform[g[x],x,p]

I always get the error that the recursion limit and the iteration limit were
exceeded...

what am I'm doing wrong?

Any help is appreciated

thanks

Eckhard
