I get this exception when I try to request collection of related entities (using EJB3 relations). When I try to access from local client (session bean) everything is ok. But when I try to access from remote client I get the exception... Exception in thread "main" org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: my.Entity1.relatedCollection, no session or session was closed | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:358) | at org.hibernate.collection.AbstractPersistentCollection.throwLazyInitializationExceptionIfNotConnected(AbstractPersistentCollection.java:350) | at org.hibernate.collection.AbstractPersistentCollection.readSize(AbstractPersistentCollection.java:97) | at org.hibernate.collection.PersistentBag.size(PersistentBag.java:222) | at my.TestClient.main(TestClient.java:31) Is it possible to access to the collection from remote client at all?
