All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class FrontendServlet
extends javax.servlet.http.HttpServlet

This is a servlet that's intended to be a base class for a DS component exposing a Servlet service that plugs into the OSGi web whiteboard. The servlet will scan the classpath for resources matching the request pathinfo (minus any webcontext added to the servlet path) and serve the resources with a content-type determined by the file name extension. In addition the servlet supports a list of aliases for index.html that exists to support reload of paths created by the react router. In a subclass, this list can be set by calling the setRoutes(String...) method.
