I am new to EJB , I have some very basic questions about EJBs .
I read that the bean interacts with the container through one of three mechanisms Callback methods , EJBContext interface or JNDI.
My questions are
What are the call back methods, are these the methods in Session and Entity beans interface like setSessionContext(),ejbRemove(),ejbActivate() etc??
How EJBcontext interface can work for a bean to interact with the container?
How JNDI can make a bean intercat with the container???
I will be really Thankfull if some one can explain in detail ~
Thanks in advance
