Hey Timothy,
yes you are allright and a colleague and me found out that we have to transform the object in the RPC call. Therefore gwt offers a method :
net.sf.gilead.gwt.clone(Object hibernatePojo)
this transforms the object to POJO.
Thanks for your post!

The basic answer is you cannot. You will need to transform the Hibernate object into a POJO to make it serial, this is a requirement of any object being passed between the client and the server in GWT.Tim...On Jul 30, 2014, at 5:07 AM, Peter S. <stoffel...@googlemail.com> wrote: Hey all,
after searching the complete web for a solution and didn't find one, I will try to share my problem with you ;)..
Well I have the famous failure with GWT and Hibernate:
java.lang.RuntimeException: com.google.gwt.user.client.rpc.SerializationException: Type 'org.hibernate.collection. PersistentSet' 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 = []
