public class ThumbnailServlet
extends BaseServlet

Handles the display of local metadata thumbnail images.

Most thumbnails are remote urls and are accessed through standard HTTP.
The images for some metadata thumbnails are stored within the DBMS. These typically come from metadata that is being created/edited through ArcCatalog. These images are retrieved by the browser through this Servlet. A sample url to access this servlet:
<img src="/GPT9/thumbnail?uuid={6153A394-70A9-4311-A6DC-582F2F9758FF}"/>
