How to push a message from server to clients

[guidok]

Hello,

first things first:

SmartGWT - Version (Developer Console): SmartClient Version: v10.0p_2015-10-03/EVAL Deployment (expires 2015.12.02_09.33.55) Licensed to: Isomorphic Software (#ISC_EVAL_NIGHTLY)
Browser Version: Google Chrome - 45.0.2454.101 m

Now to the topic:

I've created a data source that communicates with a backend system via socket connection.
It is possible that the data of the backend system is changed without any action from the SmartGWT system.

When this happens the backend system fires an event on which I'm listening in my DMI handler and then try to execute the following method:

private void sendToClients() {
        log.info("JOBHANDLER - sendToClients");

        final DSResponse resp = new DSResponse(-1);
        ISCMessageDispatcher dispatcher;
        try {
            RequestContext ctx = new RequestContext();
            dispatcher = ISCMessageDispatcher.instance(ctx);
        } catch (Exception e) {
            log.info("JOBHANDLER - Could not create dispatcher!");
            e.printStackTrace();
            return;
        }

        log.info("JOBHANDLER - sendToClients - ISCMessageDispatcher instantiated");

        final Map data = new HashMap();
        data.put("invalidateCache", resp.getInvalidateCache());
        data.put("operationType", DSOperationType.UPDATE);
        data.put("records", resp.getRecords());

        try {
            dispatcher.send(new ISCMessage("gridUpdates", data));
            log.info("JOBHANDLER - sendToClients - message sent");
        } catch (Exception e) {
            log.error("JOBHANDLER - Could not send update message");
            e.printStackTrace();
        }
    }

This approach is working up to the point where i try to instantiate an ISCMessageDispatcher, then the following output appears:

However, when I start the mentioned method from a client call like "fetch", the the sendToClients() method works without any problems. I think that the ISCMessageDispatcher is missing some kind of context, but I can't provide any, because the communication to the clients is initiated by an event from the backend system.

What is the approach of getting this done?

Thank you very much.

[Isomorphic]

The important thing here is

java.lang.ClassCastException: com.isomorphic.messaging.LocalMessageDispatcher cannot be cast to com.isomorphic.messaging.ISCMessageDispatcher

However, LocalMessageDispatcher is a subclass of ISCMessageDispatcher, so the casting complaint doesn't make sense. Maybe you are loading multiple JAR versions? Or you have created your own implementation of com.isomorphic.messaging.LocalMessageDispatcher that doesn't extend ISCMessageDispatcher? Note, you can discover where those two classes are coming from with the Java option -verbose:class

[guidok]

I've tried the option -verbose:class:

[Loaded com.isomorphic.messaging.ISCMessageDispatcher from file:/C:/temp/smartgwtee-5.0p/lib/isomorphic_realtime_messaging.jar]
[Loaded com.isomorphic.messaging.LocalMessageDispatcher from file:/C:/temp/smartgwtee-5.0p/lib/isomorphic_realtime_messaging.jar]

It looks like both LocalMessageDispatcher and ISCMessageDispatcher are loaded from the same .jar file.
I'm using the standard LocalMessageDispatcher, which gets instantiated by (code from first post):

 
 dispatcher = ISCMessageDispatcher.instance(ctx);

This is the output with the -verbose:class option enabled:
