Subject How to avoid using too much memory to create relatively large PDF file
Date Wed, 14 Nov 2001 14:15:30 GMT

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/xsl 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 exactly when FO is processed to create PDF file.  
My FO create from my XML data and XSL is as large as 1.5M.  Does any one 
have any idea how can I avoid occupying too much memory.

Thanks in advance for your suggestion.
