A server app that submits XML purchase orders to a vendor WS needs to receive an XML document in return as a validation message, While the vendor WS takes the XML purchase order, the validation message will come back as another XML document. That XML documenr may be received by a web page or a WS. Is a web page simpler and easier to implement than a WS? Please advise a good way to create such a web page or WS using VS2005? Thanks.
