Database Connection Technologies from JSP Pages and Java Web Application Servlets

Abstract

The purpose of the study is to demonstrate the diversity of solutions on the issue of connecting to a database, including a description of the developed connection controller class, as well as various ways to create connection pools on a web server and application servers. The article discusses the practical issues of using JDBC technology when building a Java web application. In the examples, the presentation and business layer of the application are developed using JSP-pages and servlets, the database operates on the MySQL platform. The described methods for creating and configuring a connection pool are shown on the example of the ApacheTomcat web server and the GlassFish application server. The question of optimizing database connections in Java applications remains open, despite the diversity of solutions. The study examines and proposes methods for constructing classes of connectors, various methods for creating pool connections, and describes the results of solving problems arising from the implementation of the described techniques. A detailed classification of ways to connect to the database is given.
