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.

Answer 1

Look in your JBoss bin folder for the file run.bat (run.sh on Unix)

look for the line set JAVA_OPTS, (or just JAVA_OPTS on Unix) at the end of that line add -Xmx512m. Change the number to the amount of memory you want to allocate to JBoss.

If you are using a custom script to start your jboss instance, you can add the set JAVA_OPTS option there as well.
