You can set
gov.nasa.worldwind.avkey.OfflineMode
in the WorldWind properties file. This will stop WorldWind from trying to load fragments and will rely only on the local cache.
However, you may need to populate the local cache by looking at a specific area of ββinterest or installing cache packages.
Unfortunately, the site ( http://www.worldwinddata.com/ ), which is used to host cache packages, no longer works (domain has expired).
