Dear Justin,
     I appreciate your attention to this issue. Now, I will explain my
overall scenario. I'm using JMS to produce notifications for my end-users
to remind them of certain actions. This JMS (in spring boot) sends messages
to the ALERTS queue. I need to write a consumer to listen to this queue and
retrieve messages from the ALERTS queue. Therefore, I have decided to use
MQTT in Angular for this task. Could you please guide me on how to achieve
this?

Looking forward to your prompt action
