I am getting the following exception:
EVERE: [1240903589531000] javax.servlet.ServletContext log: Exception
while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type
'org.datanucleus.store.appengine.query.StreamingQueryResult' was not
included in the set of types which can be serialized by this
SerializationPolicy or its Class object could not be loaded. For
security purposes, this type will not be serialized.
