Hi,
I'm trying to run a query and I get the following error (see trace
below).
Does anyone know what causes this error?
I get the error when I run the following line.
If someone could give me some pointers I'd be grateful.
List budgets = kontext.performQuery(query);
//--section that I'm trying to get to work--
DataContext kontext =
BasicServletConfiguration.getDefaultContext(session);
SelectQuery query = new SelectQuery(Budget.class);
List budgets = kontext.performQuery(query);
//------------------------------------------
//--if I run an sql template type of query it works--
// SQLTemplate rawSelect = new SQLTemplate(Budget.class, "select *
from BUDGET", true);
// rawSelect.setFetchLimit(1000);
// List artists = kontext.performQuery(rawSelect);
//--Stack trace---
