The following query SELECT taskId, taskName FROM TaskList AS a doesn't return list of tasks instead it will return list of objects, each item in the list describes one row as another list of objects. Each item in the latter list describes one column (e.g. taskName as String). if you want it to return list of tasks that has only taskid and taskname populated you can you use the following query SELECT new TaskList(taskId, taskName) FROM TaskList AS a ofcourse you will need the above constructor for TaskList View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217278#...
