You are not supposed to use the actual attribute name, you are supposed to
use bean syntax.
_name is a private attribute- so Castor will not be able to access it
directly.
In your case, the setter & getter for the _name attribute are setName &
getName.
By bean syntax, therefore, your object would have an attribute called
"name".
so your query syntax would be:
SELECT d from Product d where d.name = 'toto'
Don't remove "_" from the attribute- remove it from the query.

stay cool,
Spaceman Spiff
You imagine me sipping champagne from your boot
For taste of your elegant pride
I may be going to hell in a bucket, babe
But at least I'm enjoying the ride, at least I'll enjoy the ride.
