Examples of org.eclipse.jetty.servlet.ServletContextHandler

org.eclipse.jetty.servlet.ServletContextHandler
Servlet Context. This extension to the ContextHandler allows for simple construction of a context with ServletHandler and optionally session and security handlers, et.
```
 new ServletContext("/context",Context.SESSIONS|Context.NO_SECURITY); 
```
This class should have been called ServletContext, but this would have cause confusion with {@link ServletContext}.
