How to increase heap size for jBoss server

Question

I have an upload files scenario in my project. When I\'m trying to upload the large files it\'s giving me an OutOfMemory error. That error is related to Java heap size.

Edit the following entry in the run.conf file. But if you have multiple JVMs running on the same JBoss, you might want to run it via command line argument of -Xms2g -Xmx4g (or whatever your preferred start/max memory settings are.

if [ "x$JAVA_OPTS" = "x" ]; then
    JAVA_OPTS="-Xms2g -Xmx4g -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true
