Yes, that's possible. OJB provides "RowReaders" 
(http://objectbridge.sourceforge.net/tutorial3.html#rowreaders), that 
allow to build such  aggregate mappings. It's not as elegant as with 
TopLink, but it will safe you a lot of money :-)

See: http://objectbridge.sourceforge.net/tutorial3.html#rowreader-example
for an example.

cheers,

Thomas
