Re: [eclipselink-users] OneToOne AND ManyToOne Mapping works with FetchT

[Tom Ware <tom.ware@xxxxxxxxxx>]

This exception generally happens when our dynamic weaving is not working 
properly.  My knowledge of the issues related to getting this working on Spring 
is limited, but I believe you need to run with a specific Agent that is provided 
with the spring framework to allow it to work.  Here is a post I found:

http://www.nabble.com/Weaving-in-Spring-problem-td20003299.html

If that is not helpful, you could try static weaving:
