Play FAQ: How do I run the Play Framework web server on a different port than the default port (9000)?
Solution: At the Play console, instead of just typing "
run" to run the server, type "
run 8080" to run the server on port 8080. Here's the command at the Play console prompt, and the output:
[forms] $ run 8080 --- (Running the application from SBT, auto-reloading is enabled) --- [info] play - Listening for HTTP on port 8080... (Server started, use Ctrl+D to stop and go back to the console...)
