I have created environment variable JAVA_OPTS and value part : -Xms512m -Xmx8192m after that i have also tried CATALINA_OPTS but it is also not reflecting the changes. In task manager java is using only upto 256 MB.

However the alternative is to use a launcher. On windows I'm using 'launch4J', that allows you to create an exe file out of a jar, specifying such jvm parameters (+ the application icon, version and copyright info, etc...). The exe will look for the jvm on windows then will execute the jar main class with your selected parameters.theRippernoreply@blogger.comtag:blogger.com,1999:blog-28228406.post-33419525203208930962009-09-30T14:56:31.448-04:002009-09-30T14:56:31.448-04:00ksksWheatieshttps://www.blogger.com/profile/04967183284484047446noreply@blogger.comtag:blogger.com,1999:blog-28228406.post-30935804358970540552009-09-29T18:30:32.511-04:002009-09-29T18:30:32.511-04:00Also, to zip it up, it has to be written on the d...Also, to zip it up, it has to be written on the disk, or unless you tell me you can zip the half cooked file, and actually that's when it fails....
