使用Applet使用桌面应用程序打开文件

Question

somehow I want to open a file form a web application with the desktop application from client side.

My boss told me to use Applet . I've been through all the internet could provide me, but still can't find how to do it.

I've build a code program from java class to open the file directly but I can't make the applet running from JSP file.

Here's my code :

public static void main(String[] a) {
      try {
  URI uri = new URI("your/local/file/path");
  Desktop desktop = null;
  if (Desktop.isDesktopSupported()) {
    desktop = Desktop.getDesktop();
  }

  if (desktop != null)
    desktop.browse(uri);
} catch (IOException ioe) {
  ioe.printStackTrace();
} catch (URISyntaxException use) {
  use.printStackTrace();
    }
 }

If somebody ever done it before, I'll be really thankful.

Normally, Applets do not have access to the local file system due to security issues. However, there are ways to grant file system access to applets. This article describes the procedure: https://www.developer.com/java/other/article.php/3303561/Creating-a-Trusted-Applet-with-Local-File-System-Access-Rights.htm . Altough I have not tested it myself and it is rather old, the article seems promising. I hope, this helps you.
