Java Web: Servlets, JSP, MySQL
In this sample, we present a program using servlets, Java Server Pages (JSPs), and a connection to the MySQL database. The database is called “Student” and has one table with the same name.

Also, all properties of the connection to the database are saved in the appropriate file called “base.properties”. Here are its contents:
