Hey Techfans,

Knowing that EJB is a server component which "encapsulate business logic" in an enterprise system, I was wondering if there are any EJB expert out there who can enlighten me on how EJB actually "encapsulate business logic" in the server side ? Sorry I'm kind new to this tech, so I'm trying to get up to speed to it.

Never heard of it, but I suspect a new member from EJB will respond shortly, in a post of questionably coincidental timing.

I understand that many vendors out there are offering applications based on the EJB architecture. I just don't really understand how does EJB actually benefit the entire application architecture. Especially the part on encapsulating business logic.

That's what I got from google. In that case the "encapsulate business logic" will probably be done by a team made up of people from the vendor and your org.

Yeah , EJB = Enterprise Java Beans. It's definite that this encapsulating will be done by a team of application developers. Basically, I would like to know how do they go about implementing such tech to the server.

so this is strictly an opinion. But years ago we upgraded/merged some of our labs databases/software into a single application customized for laboratories.

What happened was we had to define our "business rules". We called them "processes". When the vendor's PM (project manager) came out we then discussed what their database & apps would allow us to customize. When we had that part of the process started the vendor sent a programmer to work with us for further customizing.

What I'm trying to say is the vendor already had a generic application. Everything they did started from that. Of course each customer would have their individuality and require some customization. But if their app couldn't do it we didn't get it. Despite the fact the sales people had promised it.

I realize this doesn't help you with EJB. But your application development will probably be similar. Hopefully this helps some.

BTW: This process took several months to complete.
