Just a little more on this.

A quick way to view your v5d file would be to use the main method
in Vis5DForm by running:

java -Xmx256m -classpath visad.jar visad.data.vis5d.Vis5DForm 
"filename"

where "filename" is the name of the file.  This will construct
a simple display of the data, mapping all variables to IsoContour.

If you take a look at the main method source, you could see how this
is done and weed out what you don't want to create the display.
Add in a button which would call the captureDisplay method
above and you should have all you need.
