GWT only supports a set of JRE classes client side. This is because it
has to be compiled into JavaScript. A complete overview of supported
JRE classes that can be used client side can be found here:
http://code.google.com/webtoolkit/documentation/jre.html
FYI, server side you can use any class you want.
Hope this helps.

If you want to do date manipulation, I'm not too good with that on the
client. I seem to see most folks doing basic validation on client,
then having server do advanced stuff.
