I have a webservice deployed in WLS 8.1sp5. I have configured few users in the WLS. From my Java Client generated using the <clientgen> process I am calling the webservice by StockQuoteProvider sqp = sqs.getStockQuoteProviderPort ("juliet", "mypassword");. I need to know how I can call my WebService from .NET with the credentials provided . Is there any way I can specify the credential while Adding the web reference to my project?
