I'm using Amazon's GPU cluster to experiment with some HPC java code on CentOS.

The Java application is in JNLP format and has a GUI.

I've followed Amazon's getting started video, but I'm not sure how to use a web browser or otherwise download the file.

Secondly I'm not sure how to launch this file since it requires a GUI.

Any assistance would be appreciated.

Launch it with javaws (java webstart),

e.g javaws ~/Downloads/ContestAppletProd.jnlp

  • +1, thanks. I'm sure I don't run this in SSH.. do you have any tips on where I run this? Sep 6, 2012 at 3:26
  • @makerofthings7 you run this on your computer, not on the server side, you need to have java installed on your local machine
