Hi there, I'm a newbie with GAE, I'm using JPA to access datastore and I'm having a problem querying datastore.
I have successfully inserted a few record into datastore using JPA but I can not read them back from datastore. Following is my code to query datastore. ------------------------------------------------------------------ EntityManager em = EMF.get().createEntityManager(); Query query = em.createQuery("select t from com.test.dataschema.User_JPA as t"); List<User_JPA> result = query.getResultList(); ------------------------------------------------------------------ EMF class definition: package com.fineart.dataschema; import javax.persistence.EntityManagerFactory; import javax.persistence.Persistence; public final class EMF { private static final EntityManagerFactory emfInstance = Persistence.createEntityManagerFactory("transactions- optional"); private EMF() {} public static EntityManagerFactory get() { return emfInstance; } } ------------------------------------------------------------------ I would be so grateful if someone help me out. Thanks. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to google-appeng...@googlegroups.com.
