Hi . I am a beginner to EJB technology .
I have few questions , if any one can explain the answers , that would be really
appreciated . Thanks in advance :



1) Is Remote Method Invocation part of Java SE or Java EE? Why?

2) In EJB role-based development, which roles do you play?

3) Would EJBs be used to consume web services provided by other applications, or
to provide web services to other applications?

4) What is the name of the Java EE Reference Implementation? is it glassfish ?

5) Which Java EE containers comprise the middle tier of a multi-tiered application?

Are these some interview questions? I would suggest, that before looking for answers to these specific questions, you would find it useful to read some books on EJB(3). Search this forum and you will find some of the recommended books.

These are not interview questions .
They are some assignment questions .
I tried to solve them and get the answers of few of them
but i am not sure if i am correct or not .

If you can help me , that would be great .

Ved,
For assignment/homework questions, we ask people to post the answers they think are correct and we can comment on them. That way we know the person did the thinking. For example, I'm pretty sure you know #1.
