We successfully completed a Tour on EJB . We looked at how an EJB is identified. How many different types of EJBs’ are there and what each EJB type implements. Why
LocalInterfaces were introduced. We disected the EJB and went deeper into each part i.e. BEAN
Class, Remote Interface, EJB Object, Local Object, Local Interface, Home Object. We looked
Into the deployment descriptor and also seen all the files in EJB–Jar. We looked into each Beans
Methods and also learned why we needed those methods. We had done 2 different Beans
examples and we were directed to the Web links where all the examples are demonstrated. Once
you can get an idea of all the Interfaces, methods & exceptions raised, you can attempt to try
some examples to get familiar and master EJB. There are nearly 100s’ of Application servers
but in this presentation you can see a few majorly used AppServers sample implementation
web links. Just download any one of them and try out for yourself.
Now you know
