Hey everyone!
I'm developing a GWT + Spring + Hibernate app. I got GWT +Spring
working.But when I implemented hibernate and my services and run my
app then I get this error:

[WARN] Exception while dispatching incoming RPC call
com.google.gwt.user.client.rpc.SerializationException: Type
'org.springframework.orm.jpa.JpaSystemException' 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 =
org.springframework.orm.jpa.JpaSystemException:
org.hibernate.PersistentObjectException: detached entity passed to
persist: com.karq.saatekava.shared.dto.TelekanalDTO; nested exception
is javax.persistence.PersistenceException:
