How do the six transaction attributes map to isolation levels like "dirty read"? Will an attribute like "Required" lock out other readers until I'm finished updating?

Robert Castaneda

The Transaction Attributes in EJB do not map to the Transaction Isolation levels used in JDBC. This is a common misconception.

Transaction Attributes specify to the container when a Transaction should be started, suspended(paused) and committed between method invocations on Enterprise JavaBeans.

For more details and a summary of Transaction Attributes refer to section 11.6 of the EJB 1.1 specification.
