B4J Question WEB app - computer name

[besoft]

Hi,

Is it possible to get the web application computer name on which the application is running?

What do you mean with "web application computer name"?

On Windows you can get the computer name from the environment variable:

Dim name As String = GetEnvironmentVariable("COMPUTERNAME", "")

Thx

That's what I was looking for.

The idea was the name of the computer, which is connected to an application on the server.

My mistake. This code returns the name of the computer on the server side. I need on the client side.
I found this http://stackoverflow.com/questions/20492186/get-client-machine-name-in-lan:

public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {

    Logger.getLogger(this.getClass()).warning("Inside Confirm Servlet");
    response.setContentType("text/html");

    String hostname = request.getRemoteHost(); // hostname
    System.out.println("hostname"+hostname);

    String computerName = null;
    String remoteAddress = request.getRemoteAddr();
    System.out.println("remoteAddress: " + remoteAddress);
    try {
        InetAddress inetAddress = InetAddress.getByName(remoteAddress);
        System.out.println("inetAddress: " + inetAddress);
        computerName = inetAddress.getHostName();

        System.out.println("computerName: " + computerName);


        if (computerName.equalsIgnoreCase("localhost")) {
            computerName = java.net.InetAddress.getLocalHost().getCanonicalHostName();
        }
    } catch (UnknownHostException e) {

        }

    System.out.println("computerName: " + computerName);

Can anyone review this. Is it possible to run this inside the B4J?

I tried, but it shows some errors. Because my knowledge is not extensive enough, I do not know to fix errors.

This code will only work if both the client and the server are in the same local network (and the DNS is configured properly).

You can send the computer name in the request.
