I think you need to spend some more time reading the manual.
Anyway, change you query to :
Code:
"select u.uno, u.uname from User u "
which will result in an List of Arrays with two entries.
Your debugger can show you the details if your unsure,
Or to collect the complete User class try:
Code:
"from User"
which collects a List of all User objects.
Please note User should have the full path to the class.
Code:
"from my.project.User"
HQL has its basic structured based on SQL (as much of it can be passed directly to the SQL engine). Just need to get use to the object aspects of it.
