I am not understanding what you mean unfortunately.
If I remove references to objects inside objects I effectively break my
model. How would I go about setting references to null if I am doing a
straight "Select o From AccountType o"?
Unless there is a better mechanism to select all the objects I am at a loss
here.

Subject: Re: Infinite XML Loop
That exception typically comes from JAXB marshaling code when it detects
a cycle in the object graph. Are you returning the object from a web
service? Your in-memory object probably has the bidirectional references
set up, this can happen if you traverse the relationships in your code.
So, instead of relying on fetch type, you should explicitly cut the
cycles in the graph by setting some references null.
Thanks,
Sahoo
