I'm starting a runnable jar from a java app ( also headless runnable jar).
Tried both Runtime.getRuntime().exec()
and ProcesBuilder
method. The process gets launched just fine, but on the Mac ( 10.6 ) it shows the name of the jar I'm starting in the main menu bar and also puts in the dock Is there a way to prevent that ? Interestingly, if you start a jar with java -jar from the command line the jar name does not appear in the menu bar or process dock.
Any ideas?
Thanks
Andy

To enable it globally instead of adding the option to each process, set the JAVA_TOOL_OPTIONS variable like this in your .bashrc/.zshrc start up script.
export JAVA_TOOL_OPTIONS='-Djava.awt.headless=true'
