Unsupported Features of JPA

The following features of the JPA interface are not supported by the App Engine implementation:

• Owned many-to-many relationships, andunowned relationships. You can implement unowned relationships usingexplicit Key values, though type checking is not enforced in the API.
• "Join"queries. You cannot use a field of a child entity in a filter whenperforming a query on the parent kind. Note that you can test theparent's relationship field directly in query using a key.
• Aggregation queries (group by, having, sum, avg, max, min)
• Polymorphicqueries. You cannot perform a query of a class to get instances of asubclass. Each class is represented by a separate entity kind in thedatastore.

Problem with query <SELECT count(entity.name) cnt FROM NameCard entity WHERE entity.name LIKE :name>: Unsupported method <matches> while parsing expression: InvokeExpression{[PrimaryExpression{name}].matches(ParameterExpression{name})}

org.datanucleus.store.appengine.query.DatastoreQuery$UnsupportedDatastoreFeatureException:Problem with query : Unsupported method <upper> while parsing expression: InvokeExpression {[null].upper(PrimaryExpression {station, usState})}

org.datanucleus.store.appengine.query.DatastoreQuery$UnsupportedDatastoreOperatorException:Problem with query <SELECT station FROM com.newsplore.weather.bo.Station station WHERE UPPER(station.name) LIKE :stationName ORDER BY station.name>: App Engine datastore does not support operator  LIKE
