Use JSP to read remote files and save them to a local device

Reading network files is somewhat different. I will give you a complete code and save it as JSP to run it directly.

String Port = "8080"; // firewall port

If your machine has set a firewall, you need to add it. If you directly connect to the Internet, you don't need.
