1. Make it a habit to mention the source of the code you took link[^]
2. By simply copying and pasting the code from that source to the jsp and expecting it to work is not always the case. so the only advice I tell you is first understand what is a JSP? what is a Servlet? and the relation between them?
3. Always remember R&R i.e. Request and Response in web development.
4. Other path is to use an Applet.
