Some things I'm not clear on from your post: 1) Did you inherit the commons module in each of your *.gwt.xml files? 2) When you did the jar packaging, did you include the java source for the client-side? 3) Are your public resources (i.e. CSS) located in a ".../moduleName/ public/" folder? Were they included in the jar? 4) Was your commons.gwt.xml file included in the jar?
