Continuing my work on InfoPath I've completed the web service interface in Siebel based on very simple web service contracts that are easy for the rules engine in InfoPath to use. I will walk through the process of setting a reference to the web service and configuring an InfoPath form to use the service.
Firstly - InfoPath uses the WSDL file that Siebel produces on the Inbound Web Service page to create the internal proxy. If you don't know what WSDL is then it's best to learn about it and then continue.
1. Save the wsdl from Siebel into a convenient location
2. Open up an InfoPath form and open up the Data Connections window available from Tools, Data Connections
4. The next dialog asks what the source/destination of the data connection. Select Web Service
I'll go over how to actually use the web service in a future post. (Code free!)
