datetime

I'm running this query:

SELECT FROM com.Data WHERE entryDate > DATE('2010-3-16')

I get this error:

org.datanucleus.store.appengine.query.DatastoreQuery$UnsupportedDatastoreFeatureException: Problem with query DATE('2010-3-16')>: Unsupported method while parsing expression: InvokeExpression{[null].DATE(Literal{2010-3-16})}

The same query works when I use it on the admin console. But it does not work for code (java), either locally or when deployed. Any ideas?
