jdo

This page describes an 'IN' operator that can be used in GAE Datastore to compare a field against a list of possible matches, not just a single value:

However this is for Python. In Java (App Engine 1.2.5), trying

query.setFilter("someField IN param");

on my javax.jdo.query fires a JDOUserException 'Portion of expression could not be parsed: IN param'.

Is there a way this can be done?
