Hi all,

I'm web app developer uses JSP/Servlets and Struts ! I work on "localhost" i.e on single machine , I developed the e-commerce application , developed it and deployed on real server using Tomcat !

Now I want to learn EJB and like to implement it on my current e-commerce web application ? So In my case , is there any use of EJB ?

I dont know anything about EJB .

EJBs are handy to know if you want to build distributable applications. EJBs can be used as local or remote objects. If you haven't used or learnt Spring & Hibernate, I would learn that first before EJBs. Go to EJB3 directly.

So you want to say EJB and EJB3 are different ??

EJB came in a variety of versions over the years (1.0, 1.1, 2.0, 2.1 and 3). Version 3 is quite different from 2.x. So you should make sure that you're not inadvertently learning an older version (or using a server that doesn't yet support EJB 3). If you're seeing talk of "annotations", then you know that EJB 3 is involved.
