Portfolio server Webservice Accessing Error

[mahesh]

Hi
I am trying to access Portfolio server Webservices(PPSI)
in SDK I find one sample based on this I have created a new .NET Solution
that is working fine.It is populating the Portfolio's List in a Grid.This is
Windows appliaction.

But the same application I need to create a .NET Webservice that will return
a Dataset containing all portfolio's list.

This is not working I have done same as in windows application.

am unable to understand the problem
Rrror is:
System.Web.Services.Protocols.SoapException:
