The JW player is not a publishing client it's a playback client. To play a live stream from Wowza first you must publish the stream to Wowza which can be done using an encoder.
To play the stream via Apple HLS once it's been successfully published, please follow the Simple RTMP and Apple HLS streaming section of the JW player article.
You'll need to replace the application name and stream name as required.
Current example (for video on demand):
This example assumes you're using the application called "live" and that you're publishing a stream called "myStream".
