I tried to increase memory of JVM through Tomcat - but not much change. I believe the way i am using my procedure (creating objects) that might be wrong.
Below is some statistics (logger is displaying) when i am trying to render the PDF with 1 page / 2 pages / 3 pages etc
1 page report 2 pages report 3 pages report
Initial Heap size ~ 12M 14M 10M
Current Heap size ~ 64M 10M 9M
Total memory used ~ 52M 4M -1M
If i try for 4 pages report then i get OutOfMemory Error. Once i get this error then even sometimes i get errors for 2 pages / 3pages report too. Total memory used always go in -ve later.
I am attaching my procedure below which i use to render the pdf
----------------------------------------------------------
//Following method is used to render PDF
public synchronized void renderPDF (...)
throws Exception {
...
get xsl file path

Well I havent used Tomcat, but I know it will be started by a shell script or
batch file. You will need to find it and add the parameter -Xmx256M to the
call to java. Ask on a tomcat specific list, this is getting somewhat off
topic for FOP/XSL-FO.
