To: Tom Cato Amundsen <[email protected]>
Thank you very much! I finally was able to run a simple exercise (I'll write
a little tutorial) without too much trouble. Looking at twelvetone was a
great suggestion! Now I have to implement some functionality,the rest seems
quite understandable and there are plenty of examples in the code.
Thank you again for helping, I'll contact you if I'm in trouble again!

What happens now with your Lotus Notes apps - do you make another costly
upgrade, or settle for being marooned without product support? Time to move
off Lotus Notes and onto the cloud with Force.com, apps are easier to build,
use, and manage than apps on traditional platforms. Sign up for the Lotus
