@ManagedObject("Servlet Context Handler")
public class ServletContextHandler
extends ContextHandler

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 ServletContext.
