What os or arch value can I use?

os and arch value collection

The current JNLP specification doesn't list the values for the os or arch attributes. Instead it states that all values are valid as long as they match the values returned by the system properties os.name or os.arch. Values that only match the beginning of os.name or os.arch are also valid (e.g. if you specify Windows and the os.name is Windows 98, for example, everything works out fine).

To make it easier for everyone I collect and publish the os and arch values here. If an os or arch entry is missing, please post your donations to the lopica-talk mailinglist (Subscribe/Unsubscribe) or send a private email to gerald@vamphq.com (Gerald Bauer) and I will add it along with proper credit in the hall of fame.

Do It Yourself Kit

To find out the os.name, os.version and os.arch values on your machine, use the source below: 

class WhatOS 
{
  public static void main( String args[] ) 
  {
    System.out.println( System.getProperty("os.name") );
    System.out.println( System.getProperty("os.version") );
    System.out.println( System.getProperty("os.arch") );
  }
}
