Oops, sorry!  I've changed my examples to add IOException where needed.

The reason it was missing is that, while writing my example application,
I made a slight improvement to visad.data.DefaultFamily, the class which
takes a String or URL argument and returns the appropriate VisAD Data
object.

Previously, the DefaultFamily open(String) method only tried to open a
local file; to open a web-based file, you needed to call the open(URL)
method.

Now the open(String) method tries to open a local file and, if that
fails, will try to build a URL from the String and open the URL.  While
making these changes, I managed to get rid of the IOException the
open(String) method used to throw.  (The latest version of VisAD on the
FTP/web site has these changes.)

Bill says he's had several reports of this bug.  It's already been
reported to Sun so you can just ignore it until they get it fixed.
