some problem with QAWF integration

[xie qiong]

Hello there,

I have an urgent question about QAWF function.
 
I need to computer a semi-infinit integration
\int_{0} ^{\infty} f(x)*sin(w*x)/x dx
The integrand f(x) * sin(w*x) / x has a finite value
limit(equal to w) at x = 0.0 but f(x) / x doesn't a
finite value limit at x = 0.0.

In this case, what can I do to make QAWF work?

If I change the lower bound of this integration from 0
to 1e-3, QAWF will work but the error is large.

Thanks.
Qiong
