.Net consumer for java webservice

[sonyram]

Hello,

I am trying to create a consumer application (console) for a java webservice
which is outside our domain. When I tried to add web reference, I was able to
locate the service after I give authentication information and I was able to
see all the methods. But when I tried to create proxy by pressing the "Add
Reference" button, I get the message "Object reference not set to an instance
of object" error. any idea why?

When I tried to check with .Net webservice studio for the same webservice,
it passes "Generating Assembly" step but fails on "Reflecting Proxy Assembly"
step, The error message was

System.InvalidOperationException: Unable to generate a temporary class
(result=1). error CS0029: Cannot implicitly convert type 'string' to
'string[]'

Thanks in advance
Ram
