Stuart,

I came across your post having just found the solution to your problem. 
Konqueror (3.4) does not find the required jar files when they are 
given as an "archive" attribute as in your example (see also  
http://ww2.cs.fsu.edu/~steele/XHTML/appletObject.html which exhibits 
the same problem). It does however load the applet fine if you add a 
parameter with a "name" attribute of "archive" just as in the IE 
specific section.

Safari on MacOs X only sees the "archive" attribute on the other hand, 
so you can't leave that out. Mozilla/Firefox does not seem to care and 
works either way.

So just add a line <param name="archive" value="lib/jupload.jar"/> to 
your outer object tag and enjoy the ride.

Regards,

Magnus
