We know that we have four isolation levels: READ_UNCOMMITED, READ_COMMITED, REPEATABLE_READ, SERIALIZABLE.

In deployment descriptor, we need to set these levels? In case of BMT, where it should be mentioned and in case of CMT, where it should be mentioned?

In CMT, you have to specify them under ejb-jar.xml. In BMT, use Connection.setTransactionIsolation().
I agree. Here's the link:
