MongoDB and GWT

After setting up mongodb, I get an error trying to setup gwt; but I can setup spring mvc.
What am I missing?

Thanks

You are right, GWT scaffolding depends on JPA currently. I opened a ticket so we can address this for the next release https://jira.springsource.org/browse/ROO-2785.

Thanks Stefan, can't wait. Nor can I wait for support for Riak :).
