It’s not exactly part five of the four part GWT series, but it is closely related. Please check out my newest article on IBM Developerworks: Simplify Ajax development using Cypal Studio for GWT.
I actually wrote this a few months ago, when the tool was still called Googlipse, and the final publication was delayed a bit while I rechecked all the code and instructions, and changed the name throughout.
One note: it seems as though the GWT 1.4 release candidates do not currently work with Cypal – you have to use the GWT 1.3 version.
Enjoy.
