Changing the default port number(9000) of a Play Application

Changing the default port number  9000 of Play Application:

In order to change the default port number, we can do it in two ways:

Way 1: In the conf/application.conf file change the default port number value.
             http.port=2015

Way 2: Passing the port number value while running the application in command line or terminal.

activator "run 2015"  - browser-reload mode
activator "~run 2015" - continuous-reload mode
