Is it possible to specify which X display the JVM is to launch it’s

  • 0

Is it possible to specify which X display the JVM is to launch it’s windows on through the JVM? I am thinking something like this

java -DISPLAY=THE_DISPLAY_I_WANT:0.1 -jar my.jar

I looked at the man pages and I can’t find anything.

or do I need to wrap my call to the jvm in a shell script like this 

#/bin/sh export DISPLAY=THE_DISPLAY_I_WANT:0.1 java -jar my.jar

I don’t want to make a script just to specify an argument that can be past directly to the JVM.

PS: No, I don’t want to change my enviroment DISPLAY variable I want to launch the JVM on whichever DISPLAY I like 🙂

Update Responding to the question ‘Why does it matter if I use the second solution’ Using the second solution, If I would like to start a jvm session on several different displays I would have to set the DISPLAY for each session.

What I am looking for is like what you can do with Xprograms

try xterm -display my_display:0.0 So my question is can I do this with the jvm, I can’t see it documented anywhere. If it can’t be done then the correct answer should be ‘No you can’t’, I already know the alternative 🙂

Thanks

  1. Given your constraints on the answer, the answer you’re looking for is ‘It can’t be done‘

    I’m still curious why the second solution doesn’t work for you. I realize it’s not what you want to do, I just want to know why
