I am trying to access the application like this :
http://127.0.0.1:9990/JAX-RS_examples/rest/HelloWorld/sayHello
And getting 404 not found.
Came across similar thread but can't figure out :
WildFly running, project deployed, but 404

Answer 1

someone already told you.
You call your REST service with the port 9990.
But, this port is form the admin console.
by default, the correct port should be 8080. So, just call:
http://127.0.0.1:8080/JAX-RS_examples/rest/HelloWorld/sayHello

Answer 2

The runtime name needs to have a .war estension.
