I am trying out seam 1.2 and jboss 4.0.5 ejb. I setup a project with seam-gen
that accesses a simple little mysql database with users and blogs. After I
call seam generate-entities, and restart seam, I get the following error trace
upon accessing the users page.
In the example below, it appears that the User object "is not mapped", even
though it has been generated by seam-gen. Same goes for my other domain
objects.
Any ideas as to what is wrong? BTW - same thing happens w/postgresql.
