Re: EJBs are Middleware means ?

Hi radhika,
Middleware is nothing but an intermediator between presentation logic and Database.

In MVC1,
HTML/JSP --> Prsentation Logic
JSP/Servlet---> Business Logic
Oracle ----> Database

In MVC2,

HTML/JSP --> Prsentation Logic
Servlet---> Controller
EJB ----> Business Logic
Oracle ----> Database

This is what MVC design pattern is.Here middleware is nothing but which takes care of business logic.

comments are welcome.

Thanks.

Regards,
R.P.Karunakaran
