I am trying to use an HQL to perform a simple update in hibernate, but i can't seem to get it to work.

i have a query template defined as:

private static final String CHANGE_DEVICE_STATUS
= "UPDATE THING"
 +"SET ACTIVE = ? "
 +"WHERE ID = ?";

and then i try to execute it like this:

Session s = HibernateSessionFactory.getSession();
Query query = s.createQuery(CHANGE_DEVICE_STATUS);
query.setBoolean(0, is_active);
query.setLong(1, id);
query.executeUpdate();

But now i get this error:

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

 at org.hibernate.impl.SessionImpl.executeUpdate(SessionImpl.java:865)
 at org.hibernate.impl.QueryImpl.executeUpdate(QueryImpl.java:89)
    ....

what am i doing wrong here? I am using hibernate 3.0

UPDATE

i changed it to

Query query = s.createQuery(CHANGE_DEVICE_STATUS);
query.setBoolean(1, is_active);
query.setLong(2, id);//<---throws here
query.executeUpdate();

without changing anything else but the parameter indexes and i got this:

java.lang.IllegalArgumentException: Positional parameter does not exist: 2 in query: 
UPDATE DEVICE_INSTANCES SET ACTIVE = ? WHERE DEVICE_INSTANCE_ID = ?
