This doesn't seem like an e-book question. So I'm locking this thread.
But the answer to your last question is simple:
- If you want to learn developing Java beans you follow the first course.
- If you want to learn developing applications that use Java persistence API's you follow the second course.
- If you don't know the difference, you follow none of the two.
How many certification are about The Business coomponent certification?
I thought there was just one, the buessiness component developer, then which is th code?
I also seen these:
