### Question:
GetSlavesServlet extends BaseHttpServlet implements CartePluginInterface { public void doGet( HttpServletRequest request, HttpServletResponse response ) throws ServletException, IOException { if ( isJettyMode() && !request.getContextPath().startsWith( CONTEXT_PATH ) ) { return; } if ( log.isDebug() ) { logDebug( BaseMessages.getString( PKG, "GetStatusServlet.StatusRequested" ) ); } response.setStatus( HttpServletResponse.SC_OK ); response.setContentType( "text/xml" ); response.setCharacterEncoding( Const.XML_ENCODING ); PrintStream out = new PrintStream( response.getOutputStream() ); out.print( XMLHandler.getXMLHeader( Const.XML_ENCODING ) ); out.println( XMLHandler.openTag( XML_TAG_SLAVESERVER_DETECTIONS ) ); if ( getDetections() != null ) { for ( SlaveServerDetection slaveServer : getDetections() ) { try { slaveServer.getSlaveServer().getStatus(); } catch ( Exception e ) { slaveServer.setActive( false ); slaveServer.setLastInactiveDate( new Date() ); } out.println( slaveServer.getXML() ); } } out.println( XMLHandler.closeTag( XML_TAG_SLAVESERVER_DETECTIONS ) ); } GetSlavesServlet();  GetSlavesServlet( List<SlaveServerDetection> slaveServers );  GetSlavesServlet( List<SlaveServerDetection> slaveServers, boolean isJetty ); void doGet( HttpServletRequest request, HttpServletResponse response ); String toString(); String getService(); String getContextPath(); static final String XML_TAG_SLAVESERVER_DETECTIONS; static final String CONTEXT_PATH; }### Answer:
