Hi all, I'm struggling to find a way how (or if) the WildFly subsystem may deploy and start a JAX-RS application. My idea is having a subsystem that starts a JAX-RS application that will be capable of serving HTTP requests. I do work with EAP7-1496 which is integration of Narayana LRA[2] to WildFly. I would like to take the Application class and get it booted on subsystem startup. I'm trying this way[3]. But it seems the JAX-RS is not launched correctly to serve the requests. I have trouble finding a way to progress on this. Is this idea achievable for the WildFly subsystem? What approach or API could I use? Any idea or best practice guidance is heavily appreciated. Thank you Ondra [1] https://issues.redhat.com/browse/EAP7-1496 [1] https://narayana.io/lra/ [3] https://github.com/wildfly/wildfly/compare/main...ochaloup:EAP7-1496-micr...
