Weird Web Services App
Posted on 2006-11-08
I am working on a client application that is kind of strange, and I’m not sure how to pull this off. The client uses a web service that was developed by another party that I don’t have access to. There are already a number of clients that use this web service on their website. It’s a simple XML post to the service, with a response. What we are trying to accomplish is the XML to be posted to a service that I would create, do some processing on that XML string, then post the same XML string to the service that is already in use, pass its response back to my service, my service would then pass the response back to the client. The reason it has to be done this way is because we only want the clients to only have to change the URL they are posting to, and we cannot make any changes to the original web service.
I have implemented web services before, but I’ve never built one. So I’m not sure how to do this. I created simple “Hello Word” web service from a tutorial that works OK, but as soon as I post the XML string to it craps out. Any light you can shed would be great. I am doing this in ASP/VB.net in Visual Studio.
