org.apache.felix.webconsole.AbstractWebConsolePlugin
The Web Console can be extended by registering an OSGi service for the interface {@link javax.servlet.Servlet} with the service propertyfelix.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 {@link #renderContent(HttpServletRequest,HttpServletResponse)} method.

     * @return The plugin or <code>null</code> if no plugin is registered with
     *      the given label.
