fetching associations

[Matthew Broadhead]

HI, I am using TomEE 7.0.1 and I just switched from Plume to Plus. I was 
using eclipselink and now I am converting to OpenJPA.  When I fetch a 
set of entities and then try to iterate through their associations in 
JSF the list is empty.  in eclipselink they were populated by default.  
if i loop through the entities in Java before displaying in JSF then 
they are populated (i guess they get lazy loaded).  is there a setting 
that needs to be changed?  like generating with all associations as 
eager or setting a flag in persistence.xml?  what would give the same 
default as eclipselink? seemed like an easy question but i could not 
find anything by searching.
