check my code below, Here I have added three alert messages to each event type, but in this code source.onopen()[alert: readyState: 1] and source.onerror()[alert: readyState: 0] works properly but in case of onmessage() it is not executed.`

       if(typeof(EventSource) !== undefined) {

           var source = new EventSource('clinic/get');

           source.onopen = function(){

             alert('connection is opened.'+source.readyState);  

           };



           source.onerror = function(){

               alert('error: '+source.readyState);

           };



           source.onmessage = function(datalist){



               alert(message: +datalist.data);

           };



        } else {

            document.getElementById(clinic-dtls).innerHTML = Sorry, your browser does not support server-sent events...;

        }`

check the code below for the server side

Random random = new Random();

        response.setContentType(text/event-stream);

        response.setCharacterEncoding(UTF-8);

        System.out.println(clinic/get got hit);



        try {

            Writer out = response.getWriter();

            out.write(data: welcome data+random);

            out.flush();

            out.close();

        } catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

I am using STS(Spring tool Suits), I am wondering, when I am using ctrl+space on EventSource (source) object, in the options it only shows onopen() and onerror(), where is the onmessage().

I will be highly appreciate, if I'd get any response. --Thanks
