An enterprise bean is a server-side component written in the Java programming language that simplifies the development of large, distributed applications. Get familiar with the fundamentals of enterprise beans and the most basic form of such beans, i.e., session beans using this course. You'll get a chance to examine the implementation of enterprise beans, set up an application server that can host enterprise beans, and explore different types of session beans. You'll also investigate how to develop a basic session bean, deploy it to the application server, and access it from a client application. Upon completion of this course, you'll have a foundational understanding of enterprise beans and how they encapsulate the business logic of an application.
