I'm working on a simple java server to accept a port number and display internet data such as text, images, and directories and am having some trouble getting some code to work. this is my class

public class HTTPServer {

    public static void main(String[] args) {
               
        ServerSocket socket = null;
     
        try 
        {
            socket = new ServerSocket(5000);
        } 
        catch (Exception ex0) 
        {
            System.out.println(ex0.getMessage());
            System.exit(1); // exit with error.
       
        }

This first part works fine but when I try to accept a connection the program stalls. The line "Waiting For Client Connection" is output to screen and then nothing happens

        while(true)
        {
            // the server waits (using an accept call) for a client to connect.
            System.out.println("Waiting For Client Connection.");
            Socket connection = null;
            
            try 
            {
                connection = socket.accept();
            } 
            catch (Exception ex1) 
            {
                System.out.println(ex1.getMessage());
                System.exit(1); // exit with error.
            }
            
            System.out.println("Client Connected To Server");
        }
    }
    
}

The next line "Client Connected To Server" is never output to the screen and exception ex1 is never triggered. I'm very confused about this. Does anyone have any suggestions?
