deploying Java app on heroku

Question

I have made an app which is exposing some REST api's( implemented using Jersey JAX-RS). Now when I deploy 'war' on heroku, the API's are not accessibe.

I've changed http://localhost:8080/myProjectNameInEclipse/webapi/ * to --> http://myAppNameInHeroku.herokuapp.com/myProjectNameInEclipse/webapi/ *

but after this the URL's are no longer accessible. Can anybody guide me on renaming URL's while deploying on server (especially on Heroku)

Answer 1

The web process must listen on one and only one port. The port must be the one specified in the $PORT variable. If your process listens on other ports, it will be shut down by Heroku.

Answer 2

Adding to the answer above. You need a Procfile to indicate the $PORT variable

web: java $JAVA_OPTS -jar target/dependency/jetty-runner.jar --port $PORT target/*.war

Procfile on heroku
