I'm trying to webstart my visad app but it is having trouble with a
NetCDF file I have in a jar file. I create a URL for the file using a
technique that works for other data I have so I assume this is a
visad/netcdf problem. Here's the Exception:

Any ideas how I can open the NetCDF file via webstart?
Does this work outside of WebStart? I would bet not.
I'm guessing that you are passing in a URL that is the
result of a Class.getResource() call which returns a URL. This
will return a URL that starts with jar:
jar:file:/C:/java/metapps/lib/visad.jar!/visad/ss/open.gif
The netCDF library uses the HTTPClient software to handle
URL's and this doesn't handle a URL like the above.
So, for now, I would say don't put it in a JAR file and put
it on the local disk or on a web server and pass in the absolute
path.
