Problem mit Gilead und Spring

[marky8264]

hey

Ich bin gerade dabei eine Web-Anwendung mit GWT, Spring und Hibernate zu schreiben. Für das Serialisierungsproblem zwischen GWT und Hibernate wollte ich Gilead verwenden. Das Problem ist jetzt, dass mir Gilead zwar alles wunderbar auf die Konsole schreibt, aber schlussendlich bekomme ich wieder folgende Exception:

Caused by: com.google.gwt.user.client.rpc.SerializationException: Type 'org.hibernate.collection.PersistentBag' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.: instance = []

	at com.google.gwt.user.client.rpc.core.java.util.HashMap_CustomFieldSerializer.serialize(HashMap_CustomFieldSerializer.java:38)
	... 76 more

Muss ich bei der Konfiguration von Gilead noch irgendetwas beachten?
Kann mir bitte jemand weiterhelfen.
