If you are having problems launching Jemboss with Java Web Start, try the following:

If you are asked to download a .jnlp file

  • ensure java web start is downloaded and you have re-started your browser.
  • if you have java web start installed and you still have this problem then your browser is not recognising the file type.

    On a Windows machine, set the "open" action for type "jnlp" to use "javaws.exe" to open files of this type.

    1. Download the .jnlp file. 
    2. Right click the .jnlp file..
    3. Select "Open with..."-->"Choose Program."
    4. Click "Other..." 
    5. Navigate to C:\Program Files\Java Web Start\javaws.exe and open it.
    6. Check "Always use this program to open these file."
    7. Click "OK."

    On a Unix machine you can add the following line to your '.mime.types' file:
    type=application/x-java-jnlp-file desc="Java Web Start" exts="jnlp"

    If a Jemboss window opens asking you to check the public server settings
    If this has just started after using Jemboss previously: Java web start may be confused and not downloading a required update to the Jemboss client to your machine. Try:

  • open up the Java Web Start Application Manager.
  • select the Jemboss icon and go to the menu 'Application'->'Remove Application', repeat this if there are other Jemboss icons displayed.
  • go back to the Jemboss home page and click on the Jemboss LAUNCH link. You should then see the transfer of the new Jemboss client to you machine.
  • if you are not getting files transferred then check the proxy settings that Java Web Start is using are correct for your site.

    or this is your first time:

  • this will usually mean that Java Web Start has the wrong proxy settings for connecting to the server.
  • the proxies can be changed in the Jemboss window asking you to check the settings. Click on the 'Proxies' tab in this window. Try turning this off by clicking off the 'Use proxy settings' checkbox.
  • to change these more permanently change the proxy in the 'Java Web Start Application Manager'. See the instructions below on opening the 'Java Web Start Application Manager'. Go to the 'File' menu click on 'Preferences' and this should show the proxies that are being used.

    To open the 'Java Web Start Application Manager'

  • on windows there is usually an icon on the desktop that can be double clicked or it can be found in the applications menu (under the START button).
  • on unix systems goto the Java Web Start installation directory and run javaws (i.e. type ./javaws &).
