My xampp version is 1.5.4a
Just want to share my solution. My application keep out of memory, especially when i trying to print report.
I have done some reseach, If you get the same problem, out of memory, very frequently.
It is 80% because of the sun jdk 1.5.
I have follow the follwing url, install other jdk to try.
SO far, the application is stable.
Tomcat_start_up.bat and tomcat_shutdown.bat
are hardcoded the java_home path.
Please change to your new jdk path.
It should be work fine.
