B4J Question how to comunicate a non-ui app with a ui app(fx)

[omarruben]

Hello, I can't find a web to implement a web server on a UI app, so I can do it with a non-ui app, but now, how to communicate messages between apps ?

There are all kinds of ways to do it. You can use ServerSocket on the server app to accept incoming connections.
A simpler and more reliable solution is to use MQTT for the communication. You can run the broker inside the server app.

ok, I did follow the chat sample and worked great, I try to use a mqttws31.js for a MQTT browser client with the chat sample, but I can't connect. I want to use a MQTT client on the web browser and I can't figure it out with the Simple Chat sample, any help would be appreciated.

I've answered your question: how to communicate between a non-ui B4J app and a UI B4J app.

I don't see how it is related to MQTT browser client.
