One small part of the ToCollege.net site is its Maven / GWT integration. While there were a number of projects that tried to make this work I found them either overkill or dead in the water.
As of today, I've released the net.tocollege.gwt_maven plugin as open source on Google Code.
See how to integrate this into your pom.xml here.
See the source code here.
And check out Pro Web 2.0 Application Development with GWT for some 400 pages of walk through of the ToCollege.net project.
