Our advice about WebSockets still applies - it's still not the right choice for most deployments, due to its lack of compatibility. However we had someone with unusual requirements sponsor it, so will be supporting it as an optional protocol in the next version.
As far as not seeing remote browsers, you can turn on both client- and server-side logging to see the messages flowing back and forth. Most likely ActiveMQ has logging you could enable as well.

also, is your advice against websocket still valid? https://forums.smartclient.com/forum...538#post198538

It turned out that there was a problem with the activemq broker.
Now the messaging in my application is working.
But the remote debug still doesn't work.
There's some logging that I may look for to discover what's going on?

Hello, thanks for your reply.
Actually there were some problems in my setup.
now I'm stuck with this error:

Is it possible to tell the framework not to use websockets?Last edited by claudiobosticco; 17 Oct 2017, 06:49.

In a clustered environment you will need to configure the real-time messaging system to use JMS, otherwise, the browser that is the target of debugging and the browser you are trying to debug with may end up connected to different machines, and not see each other. Outside of that, there's no problem using real-time messaging with clusters and load balancing.
Your error message indicates a more basic issue of just not being able to contact the server at all. You need to look at what's happening with the connection attempt - could be a simple 404, possibly caused by the messaging servlet not being installed, or some intervening layer may be rejecting the connection due to firewall rules, bad security heuristics, etc.

remote debugging not working in a clustered environment
SmartClient Version: v11.1p_2017-10-11/Enterprise Deployment (built 2017-10-11)
Hello, we're testing a clustered environment composed of two instances of tomcat 8.5 and apache (using AJP) as balancer.
I've just noticed that remote debug isn't working (while it works in non clustered environment).
I've configured it Enterprise Mode.
Firefox is logging every 3 seconds (the keepaliveInterval) this message:
Code:Firefox non puņ stabilire una connessione con il server https://mydomain/myApp/isomorphic/messaging?ts=1507910300901&isc_noLog=1&type=connect&connectionID=isc_HiddenFrame_126&subscribedChannels=%7B%0A%20%20%20%20%2267428C6A-1E68-4CD9-9E66-8DDB1DB5AEA4%22%3A%7B%0A%20%20%20%20%7D%2C%20%0A%20%20%20%20isc_DebugTarget%3A%7B%0A%20%20%20%20%7D%0A%7D&eventStream=true.
Firefox can't establish a connection to the server
is the realtime messaging implementation compatible with AJP?Last edited by claudiobosticco; 13 Oct 2017, 08:06.Tags: None
