  1. Install the commandline utilities to your desktop
  2. launch a virtual machine with your favorite distribution
  3. log in to the virtual machine
  4. excute "runlevel", you'll get an answer like "N 2"
  5. add a script in /etc/rc2.d/S98myJavaApp (assuming the default run level is 2) Put the commands here that will start your app such as "java -jar /home/javaGuy/java/javapp.jar"
  6. reboot the virtual machine, and check that your app starts
  7. take a snap shot with nova image-create virtualMachineName javaImageName

After this you can launch it in this way

#Define flavor
image="javaImageName"
#define securityGroups
#define network
command = StringFormat ("nova boot --flavor %s --image %s --key_name %s --security-groups %s --nic net-id=%s  %s",
flavor,image,key,securityGroups,network)
p = Runtime.getRuntime().exec(command);
p.waitFor();
