I have basic familiarity with Linux. We are looking at 'migrating' our Amazon EC2 Windows platform to Linux to run some JE Plus based analysis due to Linux instances being roughly half the price...

I setup the basic Ubuntu server and ran the install script for the latest Energy Plus version. I have also installed Java.

What is the best way to 'convert' our current Windows generated JEP files to run in the Linux environment? Is it best to install a GUI instead of trying to do everything via the command line? Is there a particular 'flavor' of Java that is required?

Thank you!

The jEPlus project (.jep) files will work on both Windows and Linux, so no conversion is required. If you just want to run projects, do it via the command line will be fine. However, you need to edit the jeplus.cfg file so it points to your EnergyPlus installation. To edit the project in the jEPlus GUI, however, you need to install a desktop on the Linux server. You also need to install a JRE with graphics libraries, e.g. openjdk-7-jre, rather than openjdk-7-jre-headless. Both Oracle or OpenJDK version 7 should work fine, though.
