This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I don't understand why we have 2 to go through 2 interfaces(home and component) to access a bean class. **Does this exists to make difference between different kind of beans. or any other reason??? plz clarify it??
I had the same question... When i hit... say the AdviceBean Home i am going to ultimately ask for a session object... so y cant the first call itself do everything internally and give me an Component interface?(let us ignore the casting and stuff for a while).
EJB 2.0 does not want you to access the bean directly. If you could, you would not be able to take advantage of security (which is supplied by the container generated EJBObject) and object pooling. When you utilize the Home interface, you are essentially asking the container to create a new object or to grab one from the pool. This would be more difficult for the container (and container developers) if it allow for calling the bean itself. HTH
