Dear MathGroup, 


Does anybody know why the integration routines are failing here?:

X[z_] := 1/(1 - a z^-1)
 

Needs["Calculus`DiracDelta`"]
a=0.5;

ContourIntegral = Integrate[X[E^(I w)] E^(I w n), {w, -Pi, Pi}] / (2 Pi)
(* no answer given *)
 

              I n w
             E
Integrate[-------------, {w, -Pi, Pi}]
                   -I w
          1 - 0.5 E
--------------------------------------
                 2 Pi
