Re: Why client-->home-->remote in EJB

[Konatham, Vishnu Prabhakar (CTS)]

Hi Naveen,
        The EJB architecture was made the developer to develop application
very easily. In order to achieve this it is using many services from
Application server. The necessary classes required for the distributed
computing was generated by use of applcation server tools. In order to use
the services provided by container we need to access the EJBObject through
ejbhome only.

        Inside the ejb architecture, the ejb home maintains the life cycle
of the bean. (Create and remove)
        Remote interface looks only the business methods.

If you invoke directly ejbobject, the system was not able to track so much
information which is required.


Thanks,
Vishnu.

Subject: Why client-->home-->remote in EJB


Hi EJB Gurus,

Could some please help me in clarifying my doubt here.

Why does client access an Enterprise JavaBean
by looking up the class implementing its home interface
by name through JNDI and then uses the methods
of home interface to acquire access to
an instance of the class implementing the remote interface ?

Why cannot client access the remote interface directly ?

By doing this    client --> EJBHome --> EJBObject
in the EJB architecture what advantage they get ?

It seems I am fully confused now with the EJB implementaion ?

And why did they kept all business methods in the Remote interface and
create and finders in home interface. I think I may be asking
very silly questions, but it really makes me too confusing to
understand the EJB architecture and its implementaion.

Please help me to understand better the EJB architecture.

Thanks,
Naveen.
