title: double click jar file
body: <p>I have created a swing program that displays a gui and takes user data from the respective gui. The program works fine when I am running it from eclipse. But the problem is that when I make an executable jar file and double click it nothing happens. Even if I run the jar file from console nothing happens and exception occurs. I am using scheduler and for that I am using a <code>quartz.jar</code> file. I guess the problem is not there. </p>
  
  <p>The exceptions are shown below...</p>
