why we use home interface in EJB. In RMI we dont have any concept like home interface.why we particularly go for Home Interface Both RMI and EJB are distributed applications. In EJB we use Home interface which is not avaliable in RMI. There must be several reasons for using Home Interface of EJB. can any one give reason for this?
EJB, on the other hand, is a technology built atop of RMI but does so much more than allow java objects to be distributed. It is a framework that allows you to build enterprise applications by (among other things) abstracting transactions, database access and concurent processing.
Having said this, the answer to your question is the following. The home interface is EJB's way of creating an object. Home interfaces act as factories to create session beans and entity beans. These factories are provided by the application container and take care of many low level details. Since RMI is a lower level technology, it does not offer the home interface. You would have to create it yourself.
