GWT part 3 and 4
Sorry for not mentioning this earlier, but part three of the GWT series is now up on the IBM site at:
http://www-128.ibm.com/developerworks/opensource/library/os-ad-gwt3/
This one is about remote procedure calls, and I'm pleased with how it turned out.
I just got the proofs for the fourth and final article in this series, about deployment. I expect it to be online Tuesday, Feb 27th at:
