1) Does NOT EJB support nested transaction? I saw in some article that EJB does NOT support nested transaction. If supported, How is this implemented?

2) Does EJB support 2 Phase commit? If yes, how is this supported?

3) In which of the following level(s) the isolation can be set?
a) database
b) table

4) Can we set isolation level for entity beans? If yes, how?
