Yeah, it's a large database i'm dealing with.  I simply don't have enough memory to allocate to avoid the error. 
 
I was looking at possible solutions and found some documentation about a SAX + DOM Mix (SAXDOMIX) that sounds interesting.  Link: http://www.devsphere.com/xml/
 
Has anyone implemented anything like this before.  I don't have much experience using JDOM and none using SAX.  I'm greateful for any help. Thanks.

He will probably need more if it's a very large database. Oracle can
go crazy on it's database size.
