Java Socket Server with JavaScript Client

I put together a Java socket server and client that can send messages to each other, I want to use JavaScript as a client, but... Here is what happens when I'm hosting the Java server and load the JavaScript client.

JavaScript:

    var connection = new WebSocket('ws://127.0.0.1:9005');
connection.onopen = function () {
  connection.send('Ping');
};

This Prints in the chrome console:

WebSocket connection to 'ws://127.0.0.1:9005/' failed: Error during WebSocket handshake: Invalid status line
WebSocket Error [object Event]

What I'm trying to do is send "Ping" to the Java server, but instead it sends all this stuff than disconnects...

This prints in the Java server console:

Bread Server running...
New Connection From: 127.0.0.1:51948
127.0.0.1:51948: GET / HTTP/1.1

Sounds like you are trying to connect a Websocket client to a bare socket listener in server side. notice that Websocket is not equal to socket. Websocket is a protocol on top of a tcp connection (like how http is on top of tcp) .
so you should either change your server implementation to a Websocket (you can find many java Websocket libraries in internet) or change your client to a socket.
I'm not sure how to create a socket connection in JS but this topic maybe helpful for this problem: Connecting to TCP Socket from browser using javascript
