misleading exception when the entity it not mapped

When the entity in not mapped, and I write a code like this:

final Query query = session.createQuery(hql);
if (values != null && values.length > 0) {
for (int i = 0; i < values.length; i++) {
query.setParameter(i, values[i]/, types[i]/);
}
}

I get an exception java.lang.IndexOutOfBoundsException: Remember that ordinal parameters are 1-based!

While the real problem is that the entity was not mapped in hibernate.cfg.xml file!

Please fix the error message
