Google found this description.

For the future, please try to post more specific questions. You can search Google just as easily as anyone here to find the basic definition of a term. But if you have a more specific thing you want to know, JavaRanch is an invaluable resource.

Hi sai,
If am right, you are talking about Container call back methods. If we are speaking the same language. The are methods, the container uses to manage your
beans, they can't be be called directly by a client, but could be called as a response to a client method calls. The are inherited from the interface you implements. eg for a session bean we have

setSessionContext();
ejbCreate(); // called when a client calls create() on home interface
ejbPassivate();
ejbActivate();
ejbRemove();

Notice the all have ejb in their names and must be implemented by the bean provider.

Hope it helps.
