is calling methods in here like 'helloB.hello("George"); 'without instantiating the object 'helloB' only possible in this context rght??

[ProgramJava]

@samin2012 I presume you mean "in this context" where the EJB "helloB" is in a class, and actually is instantiated by "injection". Meaning that it is created automatically by the Container, this is done by adding the annotation @EJB etc... to tell the container that you want that object created and inserted for you.

Really good; you have an upbeat voice, and that helps to follow the video. I've just tried to see two videos about java ee and the voice of the lecturer was so numb that I got lost trough them and stopped watching.
