Hi All,
What exactly is a bean, just an instance of a class which implements the methods of a business interface or something else also?
Thanks,
Amarshi

An EJB is a special class that works with an application server container. The container knows how to inject resources and add wrappers for security/transactions. An EJB is identified with an annotation or in an XML file so the container knows it is special.
