## JSP Tutorial: Downloading Music from a Website
Introduction
In this tutorial, we will learn how to create a JSP (Java Server Pages) web application that allows users to download music from a website. We will use the Servlet API to handle file downloads and the JSP API to create a user-friendly interface.
Prerequisites
To follow this tutorial, you will need the following:
* A Java development environment (JDK 1.8 or later)
* A web server (e.g., Apache Tomcat)
* A database (e.g., MySQL)
Creating the Database
First, we need to create a database to store the music files. We will use MySQL as our database.
```
CREATE DATABASE music_db;
```
Next, we need to create a table to store the music files.
```
CREATE TABLE music (
id INT NOT NULL AUTO_INCREMENT,
name VARCHAR(255) NOT NULL,
file_name VARCHAR(255) NOT NULL,
PRIMARY KEY (id)
);
```
Inserting Music Files into the Database
Next, we need to insert some music files into the database. You can use the following SQL queries:
```
INSERT INTO music (name, file_name) VALUES ('Song 1', 'song1.mp3');
INSERT INTO music (name, file_name) VALUES ('Song 2', 'song2.mp3');
INSERT INTO music (name, file_name) VALUES ('Song 3', 'song3.mp3');
```
Creating the JSP Page
Now, we can create the JSP page that will allow users to download music from the website.

Creating the Servlet
Next, we need to create a servlet to handle the file downloads.
```
import ;
import ;
import ;
import ;
import ;
import ;
import ;
import ;
import ;
@WebServlet("/download")
public class DownloadServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
String fileName = ("file");
File file = new File(fileName);
("Content-Type", getServletContext().getMimeType(fileName));
("Content-Length", (()));
("Content-Disposition", "attachment; filename=" + () + "");
try (FileInputStream fis = new FileInputStream(file); OutputStream os = ()) {
int n;
byte[] buffer = new byte[4096];
while ((n = (buffer, 0, )) != -1) {
(buffer, 0, n);
}
}
}
}
```
Deploying the Application
To deploy the application, copy the JSP page and the servlet class to the web server's webapps directory. Then, start the web server and navigate to the JSP page in a web browser. You should see a list of music files that you can download.
Conclusion
In this tutorial, we learned how to create a JSP web application that allows users to download music from a website. We used the Servlet API to handle file downloads and the JSP API to create a user-friendly interface.
