Is Nested Transactions supported in EJB3.0 ?

[tanu dua]

I read in Head First EJB that nested transactions is not supported in EJB 2.0 , while I believe I read somewhere that EJB 3.0 supports Nested Transactions.

If yes , please let me know the resources where I can read how it is supported ?

EJB 3.0 as well as EJB 2.1 doesn't support nested transaction.
You can find this in EJB 3.0 core spec section 13.1.2.
