Using Dojo for the AttributeValueProvider sample

I am following http://jazz.net/wiki/bin/view/Main/AttributeValueProviders and have a problem using dojo when writing a Provider in Java Script.
Just writing the .js script as in the movie gives "dojo cannot be resolved" error at dojo.provide, dojo.require etc lines.
Is there a step-by-step description of how Dojo should be installed to RTC in order to complete the samples ?
Thanks

One answer

I successfully installed ATF (http://download.eclipse.org/tools/atf/updates/0.3.0/) in a 'standard' Eclipse, and creating the sample Java Script file of http://jazz.net/wiki/bin/view/Main/AttributeValueProviders (with dojo.require, dojo.provide etc lines) then validated fine.
Problem now is that I do not manage to install the same ATF via the RTC 2.0.0.2 client, getting this error message:
"Cannot complete the request. See the details.
Cannot find a solution satisfying the following requirements org.eclipse.datatools.enablement.jdbc.feature.feature.jar ."
(note that I do have the 'Web Develeoper Tools' installed)
