Hi,
I am getting the error below in a JSF app when I try to fetch a
List<Template>.
Using this code:
PersistenceManager pm =
PMF.get().getPersistenceManager();//
String query = "select from " + Template.class.getName() + "
where owner=='"+owner+"' ";
this.templates = (List<Template>) pm.newQuery(query).execute();
Can you help figure out what's causing it.
Thanks.
