I have a class below and I load this object from the DB but when I call this method through with JNDI address, give some error about kullainiciGrups attribute which is a java.util.List, if this attribute removed, it works without exception. Stack trace is below the code block;

What do you think about this persistenceBag exception? Thanks.

You are sending a hibernate entity / collection. There are a few issues:

  • the collection might not be loaded
  • the endpoint might not have hibernate on its classpath.

So before sending it, you should initialize the collection and unproxy it (i.e. obtain the original collection). That may still not work, because hibernate sets its own collections that implement java.util.List. So from there you have two options:

  • create new ArrayList(originalCollection) - this will copy the elements in a ArrayList
  • add hibernate on the classpath of the endpoint.
