Can Wowza & JW Player depend only on HTML 5?

Hello!

I am pretty new to wowza and streaming. Now, I am using Wowza Streaming Engine 4 and JW Player 7.10 with vod and live stream. The problem is the playback depending on flash.

What I want is when we have no flash/flash disable, the vdo/live should be able to play. The following is how I call jw player,

jwplayer("preview_container").setup({
											sources:[{	
		file: "http://[my-server]/redirect/live/loadbalancer.smil?assets=[...]"
	},{
		file: "http://[my-server]:1935/live/[...]/playlist.m3u8"
	}],
											rtmp: 	{
		bufferlength: 5
	},
											modes: [											  { type: 'html5' },
	],
											
											width: thisWidth,
height: thisHeight,									autostart: true,
primary: 'html5',
androidhls: true,
fallback: true,
});

The question is

  1. Is it possible to make wowza only depend on html5, not flash?

  2. If so, how should I configure wowza?
