he Web services concept—connecting standardized components via well-advertised interfaces—seems as if it would make for simple programming. While there are developer tools available to ease the creation process, there is a need for detailed knowledge of the programming domain. There are several key implementation choices that make the difference between a difficult project and one that sails along.

The first article in this series described good design practices; this article will discuss specific development techniques that will get you quickly past the more complicated programming challenges that will arise.

These techniques fall into four general categories:

• Enhancing Interoperability
• Adding Security to your Web Service
• Choosing the Right Development and Testing Tools
• Preparing for Deployment
