Connecting to a ServerSocket in Java with a Javascript client

If I have a ServerSocket in Java, how can I connect to it through Javascript? This isn't a WebSocket. Here is part of my server code:

ServerSocket server = new ServerSocket(3000);
Socket client = server.accept();
BufferedWriter clientOut = new BufferedWriter(new OutputStreamWriter(client.getOutputStream()));
clientOut.write('Hello World!\n');
clientOut.flush();
clientOut.close();
client.close();
server.close();

When I try to use a WebSocket to connect, I get this error:

SyntaxError: An invalid or illegal string was specified

And this is what I use to connect:

socket = new WebSocket('http://localhost:3000')

Do note that I would also like a pure Javascript way of doing this, and I wouldn't want a Java applet hidden inside my page to send and read data through the socket.

the javascript WebSocket is different from the generic socket. if you want to use WebSockets, your java server must implement the WS/WSS handshake protocols.

there is no generic socket connections for javascript. i would suggest that you create a corresponding java socket client.
