Compare EJB to a physical system!

[Naren Chivukula]

Hi,

I'm studying the book 'MasteringEJB2'. Slowly I'm understanding the topic. I want somebody to brief the entire concept of EJB to some physical system so that I can explain in much more descriptive manner to a non-computer professional person easily. Plzz do use ur creativity to explain this. I'm not thorough in EJB to think.

I thank u,
Narendranath.

Consider it as washing machine. load the clothes (code) in it, add detergent (home/remote interfaces), specify cycles (deployment descriptors) and press start button (deploy). washing machine (container) will do the rest of work (transaction, pooling).

[Roger Chung-Wee]

A remote client only ever talks to a stub, never directly to a bean:

client --> stub --> bean

An analogy:

person --> remote control --> TV set
