Hi,
The problem is occurring when the instance of User is being marshaled
out to XML.
When you say you are using EJBs is the resource class with the
resource method "read" an EJB?
Are you setting up any transaction boundaries in your EJB? If so it
could be that the transaction boundary is terminated when the resource
method is returned. You might need to set up some lazy configuration
in this respect.
I recommend posting to the GF users list:
