There's no special JDO extension for Datastore that will automatically treat a String as Text, unfortunately. Even if there was, setting 'unindexed' for a String property wouldn't be a big enough hint to treat it as Text, because there's still a difference in Datastore between an unindexed String property and a Text property. If you want to persist a Text property in JDO, the way to do it is:
