Perhaps you should read agian my posting. My argumnt was that there 
are two problems here and you do not tell us which you want to solve. 
The problem that you asked Mathematica to solve was to determine the 
conditions for convergence of this integral in the compelx plane. It's 
not a trivial problem.
