J2EE Interview Questions and Answers

Question: What makes J2EE suitable for distributed multitiered Applications?

Answer: The J2EE platform uses a multitiered distributed application model. Application logic is divided into components according to function, and the various application components that make up a J2EE application are installed on different machines depending on the tier in the multitiered J2EE environment to which the application component belongs. The J2EE application parts are:

• Client-tier components run on the client machine.


• Web-tier components run on the J2EE server.


• Business-tier components run on the J2EE server.


• Enterprise information system (EIS)-tier software runs on the EIS server.
