Hi,
I've come out with a table as follows.
Please feel free to give your comment and correct any mistake I've made or anything you think it is useful to add.
I know cross posting is not allow, so, hopefully the guys visiting EJB forum can pop in to have a look too.
Cheers.

Oops,
It turns out to be very ugly.
I'd appreciate if the moderator convert it to a table as in the html tag.
Sorry.
