java.lang.OutOfMemory: java heap space.

jgreiner Aug 15, 2007 2:25 PM

I am using RedHat Developer Studio Beta 1, and JBoss-4.0.4 AS, that is setup separately. When I try to start the JBoss app server it gives me a java.lang.OutOfMemory: java heap space error.

Here are my eclipse.ini settings
-vmargs
-Xms128M
-Xmx1G
-XX:MaxPermSize=128M
-XX:ReservedCodeCacheSize=64M
-Druntime.environment=dev

Does anyone know if it is possible to set these values on the server start up?

Try this:

Go to "JBoss Server" view (Window -> Show view -> Other -> Server -> JBoss Server View), double click your JBoss installation, click "Open launch configuration", open "Start Args" tab. Add arguments (e.g. "-Xms256m -Xmx512m") to VM arguments. That should work. Note that this configuration is applied only for the case of launching JBoss from RHDS environment.
