title: EC2- Run jar on running EC2 instance
body: <p>I have an EC2 instance and i have a .jar that i already took (wget script command) from S3.
  I want to run this .jar file, but not on start-up, just when i decide.</p>
  
  <p>I'm using Java with "Eclipse Juno" with help from AWS SDK.</p>
  
  <p>Running a user data script doesn't help me here.</p>
  
  <p>Can some one help me with this?</p>
  
  <p>Thanks in advance.</p>
