    Hi,

    Hi,

    The error could be because

    1) The URL referenced from RWB (Communictaion Channel) is incorrect.

    Try accesing the link directly http://HOST:JAVAPORT/mdt/channelmonitorservlet

    If you are able to open the window with out nay error, it means you url referenced from SLD is wrong. Correct your SLD and update the cache.

    2) If you are not able to access above URL, it means the java service is not running to accept your request, check in visual admin if any of the services are stopped. Try restarting the same.

    Regards,

    KNS Kumar
