title: How to use One-Jar?
body: <p>I've coded an aplication that it's used to process a set of files. From each file it extracts an xml file and gets info. At the end an excell file is created containing the info extracted from each file.</p>
  
  <p>It works perfectly when I run it from eclipse, but when I try to create a jar file and run it we start finding problems..</p>
  
  <p>I had to add jars to work with xml files and to create excell files, I just learned that this is not supported. I started then to look into how to create a jar file that contains others jar files. I found this <a href="http://one-jar.sourceforge.net/index.php?page=getting-started&amp;file=quickstart" rel="nofollow">http://one-jar.sourceforge.net/index.php?page=getting-started&amp;file=quickstart</a></p>
  
  <p>(Command-Line Approach)</p>
  
  <p>In step 2, I created a jar file containing all the classes I've coded. Is that right?, in the lib folder I copied al the external jars I use</p>
  
  <p>After executing the last step all I get is a 1Kb one-jar.jar file.</p>
  
  <p>Could anyone help me with this?</p>
  
  <p>Thanks for reading all this!</p>
