Hello,
I'm getting the exception in the subject line when I try to do a
simple query. Here's the code:
PersistenceManager pm = Persistence.getInstance ();
String query = "select from " + Registration.class.getName ();
Query q = pm.newQuery (query);
List<Registration> list = (List<Registration>) q.execute ();
The newQuery() call generates the stack trace below.
I'm using GWT 2.0 and App Engine 1.3. I've also got the following
DataNucleus jars:
datanucleus-appengine-1.0.4.1.final.jar
datanucleus-core-1.1.5.jar
datanucleus-jpa-1.1.5.jar
Anyone seen this? Or have any suggestions?
Thanks,
Joe
