I'm trying to add some emf objects like in the tutorial step 3. I can
create the root object, but then when I try to add something to a list in
that object, it doesn't work. The Server object below returns an
EList<Plugin> object. When I add a Plugin object to the EList, it seems to
work, but then when I read it back again, nothing is there. I put in a
flush, and reopened the session to see what would happen, and even
re-queried, but no use. I must be doing something incorrectly. Any ideas?
public Server addPlugin(String serverID,Plugin plugin) throws
ModelServiceException
{
Session session=sessionFactory.openSession();
Query query=session.createQuery("FROM Server where id='"+serverID+"'");
Server server=(Server)query.list().get(0);
getLogger().info("initial plugin count:"+server.getPlugins().size());
session.beginTransaction();
server.getPlugins().add(plugin);
session.getTransaction().commit();
session.flush();
session.close();
session=sessionFactory.openSession();
query=session.createQuery("FROM Server where id='"+serverID+"'");
server=(Server)query.list().get(0);
getLogger().info("new plugin count:"+server.getPlugins().size());
return server;
}
Output from the log statements shows count of zero.
