Implementation of Callbacks in EJB

[Ashish Aneja]

Can anybody tell as to how can I implement a callback to client in a business logic in EJB . For ex. The call goes from the client to a session bean and the business logic in the bean requires user intervention at some point(say to enter a value). How can such a scenario be handled? If anyone has any ideas in this regards then please share with me. Thanks Ashish
