Minima JNLP
Windows
On windows the procedure should work almost seamlessly. The JNLP will be opened automatically by Open Web Start.
If NOT - right click on the file and choose 'Open With' and select Open Web Start.
Mac
If you install OpenWebStart FOR ALL USERS, which requires admin rights and will ask for a password, the file association works so that when you click the JNLP file it opens it correctly with OpenWebStart and not Java.
If you install just for you - the file association does not seem to work.. so you will need to Command+Right Click the JNLP and choose OpenWebStart to open the file..
If you chosse 'Other' - you can then set it as the default option so the next time it does it automatically..
You can do this..
