Thks for the info. You checked the "remember this application ..." checkbox
as well when you made the association, right?

I am at work right now, so I won't be able to test this for a couple of
hours. Just for the record, There's already a 'javaws' command on my "Open
with..." list for JNLP files, and I already tried permanently associating
files to it, to no avail. I'll try to remove this javaws definition and
recreate it as you did, to see if anything changes.

BTW: here at work we're using Ubuntu 10.04 (which also uses GNOME 2.30). I
just tried launching the CelsiusConverter.jnlp from nautilus (file browser)
and Firefox opened as the preferred application (!?) -- but it correctly
handled the JNLP file, opening it through javaws (but, of course, I don't
want to have Firefox as intermediary ;-)). I then tried to do what you
described:

- right-clicked the JNLP file and opened the "Open With > Other Application"
dialog
- added a custom 'javaws' command (with absolute path)
- marked the "remember this application ..." checkbox

When I clicked the "Open" button on the file association dialog, javaws was
launched. But, double-clicking on the JNLP file launched Firefox again :-(
(indeed, the first option on the right-click popup menu  still is "Open with
Firefox web browser")

?! :-(

Regards,

Andre
