Enterprise JavaBeans
Course Fee: £790
Duration: 8 Weeks
Course Objectives
Enterprise Java Beans (EJB) technology is part of a larger framework-- the Java2 Platform, Enterprise Edition (J2EE). This platform is an architecture for developing, deploying, and executing applications in a distributed environment. These applications require system-level services, such as transaction management, security, client connectivity, and database access. The J2EE platform provides these services, allowing you to focus on the business logic in your applications, not the system-level plumbing. You code the business logic in enterprise beans, reusable components that can be accessed by client programs. Enterprise beans run on a J2EE server, which functions as a middle-tier server in a three-tier client/server system.
