My Application XYZ does not work !

You can :
  1. First check if the application works fine out of JDistro !
  2. Try another (more precise) topic in this page
  3. Send us a message describing exactly:
    - The JDistro Release Number, the OS, the JDK version
    - The application version and URL (so that we can download it)
    - What steps you take to the bug...
I run my application and ... nothing happens !

You have installed an application, it works fine outside of JDistro, then you have imported it in JDistro, but when you click on it's icon, nothing happens: no window, no error message ! Here is what you can do: At the bottom right of the taskbar (on top of the desktop), there is a small list showing all the running applications. Check if yours is in it:
  1. If so, the application is running but can't display it's frame. You should try it in WHARF mode.
  2. If not, and if no dialog box appear, you have a really sever error !
  3. Send us a message describing exactly:
    - The JDistro Release Number, the OS, the JDK version
    - The application version and URL (so that we can download it)
    - What steps you take to the bug...
My Application does an error when starting !

What error message do you have ?
  • An error window like that:


    it means the application has crashed and is not compatible with JDistro.

    We would be happy to try to make it run for you, if you send us a message with:
    - The JDistro Release Number, the OS, the JDK version
    - The application version and URL (so that we can download it)
    - What steps you take to the bug...
  • An error window with this message:


    "ClassNotFoundException" means that JDistro has not found the class that starts the application, so either you entered a wrong classpath or a wrong class name when you created your icon.
A dialog box won't display

When you're using your application under JDistro, sometimes a dialog box is not displayed (in fact it's displayed behind the main window), and as it is modal, you cannot do anything except kill JDistro.
Well, this case doesn't seem to appear anymore, but it can come up anytime soon...
  • If you're stuck like that, simply press Ctrl+Alt+X to close the offending dialog box.
    JDistro will kill only the dialog box, and the application may be affected by this, but most of the time this works well.
  • To avoid this maybe you should try it in WHARF mode.
