    Either register a servlet using Servlet API 5 or use AbstractServlet
    The Web Console can be extended by registering an OSGi service for the interface Servlet with the service property felix.webconsole.label set to the label (last segment in the URL) of the page. The respective service is called a Web Console Plugin or a plugin for short. To help rendering the response the Apache Felix Web Console bundle provides two options. One of the options is to extend the AbstractWebConsolePlugin overwriting the renderContent(HttpServletRequest, HttpServletResponse) method.
