Customize ATG Dynamo Administration Page for a Component

Default interface of each component in ATG Dynamo Administration displays properties and methods. Oracle ATG provides a way to override this default behavior by each component.One such example is /atg/dynamo/DeploymentAgent where a snapshot ID can be forced. 

How-to-Code: Override the method createAdminServlet and create either a subclass or nested class as show below.

   /**
    * This is the class to add new Magic Numbers for handling Product Support Issues with file uploads
    *  
    * @see atg.nucleus.GenericService#createAdminServlet()
    */
   @Override
   protected Servlet createAdminServlet() {
     return new AdminServlet(this, getNucleus());
   }
   /**
    * this class will implement methods needed to set new magic numbers
    *  
    * @author sgatupa
    */
   class AdminServlet extends ServiceAdminServlet {
     private static final long serialVersionUID = 1L;
     public AdminServlet(final Object pService, final Nucleus pNucleus) {
       super(pService, pNucleus);
     }
     @Override
     protected void printAdmin(final HttpServletRequest httpservletrequest,
                  final HttpServletResponse httpservletresponse,
                  final ServletOutputStream output) throws ServletException, IOException {
        printCustomform(httpservletrequest,httpservletresponse,output);
        processFormData(httpservletrequest,httpservletresponse,output);
     }
     protected void printCustomform(final HttpServletRequest httpservletrequest,
                            final HttpServletResponse httpservletresponse,
                            final ServletOutputStream output) throws ServletException,
                                            IOException {
       output.println("<H1>Form to set New Magic numbers</H1>");
       output.println("<ol>");
       output.println("<li>Enter the data</li>");
       output.println("<li>Then click on Add Magic Numbers</li>");
       output.println("</ol>");
       output.println(HTML_LINE_SEPARATOR);
       output.print("<form action=\"");
       output.print(formatServiceName(httpservletrequest.getPathInfo(), httpservletrequest));
       output.println("\" method=POST>");
       output.println("<input type=text size=70 name=field1>");
       output.println("<input type=submit name=submit value=\"Add Magic Numbers\">");
       output.println("</form>");
     }
     protected void processFormData(final HttpServletRequest httpservletrequest,
                            final HttpServletResponse httpservletresponse,
                            final ServletOutputStream output) throws IOException {
           String paramValue= httpservletrequest.getParameter("field1");
              this.propertyOne = paramValue;
         output.println("<b>Operation Success. Please verify the property <i>magicNumberToFileTypeMap</i> if new magic numbers are added: </b>: "
             + newMgNumbers);
         output.println(HTML_LINE_SEPARATOR);
     }
   }
