title: How can i create executable apple .app file from my java .jar file?
body: <p>I have created an executable java Swing .jar application. It works fine on Windows. The application hierarchy is :</p>
  <blockquote>
  <p>application.jar</p>
  <p>images(Folder) .......... Contains all images the application uses.</p>
  <p>libraries(Folder) ....... Contains all external jar libraries the application uses.</p>
  <p>bundles(Folder) ......... Contains all bundle files the application uses.</p>
  <p>database(Folder) ........ Contains the database files the application uses.</p>
  </blockquote>
  <p>All the above folders exist outside the jar file. Now i am trying to create a Mac executable file (.app) from &quot;application.jar&quot; to run it on Mac so i used the &quot;Jar Bundler&quot; as specified <a href="http://www.centerkey.com/mac/java/" rel="nofollow noreferrer">here</a> but when i run the output application.app file nothing happens, nothing runs and i can't even debug it.</p>
  <p>I think the main reason is that it can't see the external folders. So is it impossible to create a .app file if the application has external folders ?
  And is there a way to debug the .app file to see what's going on ?</p>
