Hi Jr,
Three things:
1) Your <mapping> tag is not closed - you missed the slash ;-)
2) You missed the transaction context in your test application.
Sourround your query with db.begin() and db.commit()
3) you have to provide at least one attribute in the sql-tages (my
build throws null pointer exceptions if you don't do so).
sincerly
Markus

Is the name of your database xml file 'database.xml'? and is the name of
your mapping file 'mapping.xml'? The error looks like the mapping file
isn't being found... and its searching for a file called
ProductGroup.xml. (Which isn't a problem, as long as your mapping file
is called that, and is in your classpath/current directory)
