I upgraded GWT to the latest version (2.2.0), but I can't run my
project (created with GWT 2.1.0). I receive this error:
-----------------------------------------------------------------------------------------------------------------------------------------

Google Web Toolkit 2.2.0
-----------------------------------------------------------------------------------------------------------------------------------------
I don't know which SDK to install, I have a few files calles gwt-
user.jar . I tried all of them but it doesn't work.
Thanks,
Uri Even-Chen.
