Please tell me the specific difference between J2EE and EJB .
You know, they teach the kids in school that the definition is composed of the nearest kind and the specific difference. And I cannot find such a simple statement about EJB and J2EE, at least not in the first 2 pages of a Google search...

J2EE is a platform for distributed applications
which provides a set of services arround transaction management, security checks, state
management, and resource management. It uses
JSPs, Servlets, EJBs,JDBC,JMS,...
The EJBs are the part of J2EE which are transaction orientated. They make a J2EE application scalable.

J2EE is based on the component usage model. It provides complete services for components and automatic handling of some application behaviors (such as declarative transactions). The promise of the J2EE standard is that third-party suppliers (internal teams as well as external vendors) will be able to market quality components that businesses can buy and use to build systems faster and more cost effectively than if they had to build their own infrastructure.
