I just got the OpenEntityManagerInViewFilter to work (in Eclipse, have not deployed yet ) after having struggled for several days.
Do you use the EMF class from http://code.google.com/intl/sv-SE/appengine/docs/java/datastore/jpa/overview.html ? If so, that might cause your problem since it creates an EntityManagerFactory. I have modified EMF to: public final class EMF { private static EMF _instance; private static EntityManagerFactoryInfo emfInstance; private EMF() { Object o = SpringApplicationContext.getBean("entityManagerFactory"); emfInstance = (EntityManagerFactoryInfo)o; } public static EntityManagerFactory get() { if (_instance == null) { _instance = new EMF(); } return emfInstance.getNativeEntityManagerFactory(); } } where SpringApplicationContext is implemented as specified here: http://sujitpal.blogspot.com/2007/03/accessing-spring-beans-from-legacy-code.html . You still need the .size() hack after using getResultList(). -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
