Hello you should not type this into the shell: java "-Xms128m -Xmx256m" you should type: java -Xms128m -Xmx128m -cp JavaBridge.war There are no "" in it. Also this memory settings only apply for this java launch. You cannot run java -Xms128m -Xmx128m and expect that memory settings are applied later when you run a java program. Please try this: Make sure all java processes are terminated like described before and then type java -Xms128m -Xmx128m -cp JavaBridge.war David On Fri, Jan 14, 2011 at 12:57 PM, < php...@li...> wrote: > Thx for your help.
