Java EE (Java Enterprise Edition) General Discussion

Does anyone have a recommended set of steps to follow to create a web service. These steps do not have to be full blown tutuorials. Simple one liners will do.
For example,
1) Write the interface and methods
2) Write or generate the WSDL
3) etcetera.....

I am just interested in a simple guidline. As of now there are alot of technologies but no "big picture".... Sun people take note! How does it all work together. To Suns credit they are working on a step by step example, but in the meantime, please post some simple guidlines.
