How to avoid using too much memory to create relatively large PDF file

I am using most recent FOP, Xalan and Xerces to create PDF from the 
relatively large amount of data from database.

The program works like this: I first get data from database, produce XML and 
use Xalan to process xml to create FO, then I use FOP to create PDF file.  I 
am able to create PDF files without any problem, however, I need to manually 
allocate a lot of memory to process the FO (like 80M).  The vast amount of 
memory is needed when FO is processed to create PDF file.  Does any one have 
any idea how can I avoid occupying too much memory.

Thanks in advance for your suggestion.
