Description

Introduction of Java EE Core Concepts

Java EE (formerly known as J2EE) is a robust platform designed for building enterprise-level applications. It provides a set of services, APIs, and protocols that help developers create scalable, secure, and multi-tiered applications. This course covers the core concepts of Java EE, focusing on the architecture, components, and services that facilitate the development of enterprise applications. Participants will gain hands-on experience in creating applications using key Java EE technologies such as Servlets, JSP, EJB, JPA, and web services.

Prerequisites

• Basic Knowledge of Java: Understanding of Java programming concepts such as variables, data types, control structures, and object-oriented principles.
• Basic Web Development: Familiarity with web development concepts, including HTML, HTTP, and basic front-end technologies.
• Familiarity with Databases: Basic understanding of relational databases and SQL queries.
