[netCDFJava #TIC-922637]: Can't get past 'Server does not support byte ranges'

Jon,

The problem actually occurs because you are giving NetCDF-java a bad URL. In 
your example code you pass the URL:

http://myserver.com/thredds/ncss/grid/CHESS2Aggregation/DetailWholeDataset.ncml/dataset.xml

This URL just points to an XML file, causing NetCDF-java to attempt to open 
using an HTTP file handler, producing the error. However, what you really want 
to pass (I expect) is:

http://myserver.com/thredds/ncss/grid/CHESS2Aggregation/DetailWholeDataset.ncml

I don't have access to your server to actually test, but I'd expect this URL to 
give you much better results.

Hope this helps,

Ryan
