access to customers and creating a security Web

service available across the enterprise.

Best Practices / Wrap Up

Schema and WSDL first

Dont forget about key management

Tackle versioning up front

Keep it real, write a Java consumer and validate your

service interoperability Write automated unit tests

Dont forget about your customer(s) and your contract(s)
