Hey, Konstantin,

The file system allows me to write the bigger image if I just increase the threshold size, though, so the file system is allowing the larger images. That suggests to me that the exception is being thrown solely when the image size exceeds the threshold size value. I read the exception to mean something like "I can't write this tmp file because it is bigger than the threshold size value", rather than "I can't write this tmp file because the file system won't let me".

AFAIK, the said threshold determines when a file is too big to be hold
in memory and should be written to disk.  So, I think that "Permission
denied" actually comes from your file system.  You have to read the
docs (or the source code), but I guess that it tries to write to
${catalina.base}/temp (aka $CATALINA_TMPDIR, aka java.io.tmpdir ).

Best regards,
Konstantin Kolinko

Chris, I agree.  "Exceeds threshold size" or something along those lines
would be a lot more helpful.

Increasing the value of .setSizeThreshold() did the trick.  Thanks for
pointing me in that direction--I should have sent my question here about
12 hrs ago! :)
Strange that you get Permission Denied instead of some other exception.
If you are up-to-date on commons fileupload, you might suggest that they
change their error message to make it easier to understand why the error
is occurring.
