Jonathon, Probably the best approach would be to write an xslt script which would parse the OfBiz XML descriptors and generate skeleton code which could then be subclassed to put in specific processing (it may be possible to generate the whole thing, I have not looked closely enough). I am thinking of something like the juic system used by QtJambi - the new Java binding for Qt that Trolltech have currently in beta (juic was actually originally part of kdebindings but that is another story).
It may sound odd, but actually it is best not to think about HTML and Javascript when coding GWT, it just complicates things. You can include explicit HTML or Javascript if necessary, but it is better to start from the position of doing it natively in GWT. It may be necessary (or desirable) to write some GWT code to emulate specific OfBiz widgets, I have not looked closely enough to find out.
