I tried getting that to work for MRSID support on trunk; after 3 days 
(and a lot of trouble) I found the only thing that worked as to place 
the files into the JRE extensions.

I know the fragment approach does not work for Windows (strictly 
speaking it *does* work since that is how SWT functions); The problem 
here is we are expecting the Java BootClasspath ImageIO install to 
"find" our contributions we are placing in via a fragment, since it is 
this ImageIO code that is supposed to be finding us (using FactorySPI) 
we are a long ways away, and in a different classloader, from where we 
need to be.

What you could try is setting up a eclipse plug-in to hold the classpath 
based install of JAI / ImageIO extention / ImageIO-ext stuff.

In for a penny in for a pound ... and this problem has pounded me 
previously.
