[Zoo-discuss] WPS

[Anunay Sinha]

I think for now I can go ahead and use the bianries on the IIS server.
But eventually we need to integrate it with the our GIS Engine. So I Have
to build from the tree. But I can delay this part for now.
As of now if I can just run it on IIS with some test services, that will be
all.
So please provide those binaries so that I can have these services running

Also if you have some other document which can elaborate on building WPS
from the source for IIS with external libraries that will be really helpful.

Thanks for your quick response.
