Example 1 with JsonUtilHttpService

use of jmri.server.json.util.JsonUtilHttpService in project JMRI by JMRI.

the class AbstractPanelServlet method listPanels.

protected void listPanels(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    if (JSON.JSON.equals(request.getParameter("format"))) {
        response.setContentType(UTF8_APPLICATION_JSON);
