William,

Thanks for the clarifications. I have moved jai_imageio.jar to one of  
the directories you suggested.

For the uDig team: would it be possible to add the relevant  
information to the uDig OS X FAQ entry (http://udig.refractions.net/ 
confluence/display/UDIG/When+will+Mac+OS+X+support+be+available)?  
I've drafted a simple version, if that helps:

"uDig currently supports Mac OS X 10.4 (Tiger). Earlier versions of  
OS X are not supported (?) because uDig requires Java 5, which Apple  
only provides for 10.4.

"For better uDig support, you should manually install the Java  
Advanced Imaging Image I/O Tools extension (link: http://java.sun.com/ 
products/java-media/jai/downloads/download-iio-1_0_01.html) to your  
computer. There is no native OS X download, however, you can use  
jai_imageio.jar from the Linux or Windows download for pure Java  
functionality. This file should be copied to /Library/Java/Extensions  
or ~/Library/Java/Extensions before running uDig."

Regards,
Michael
