Transactions in Web Components
You may demarcate a transaction in a Web component with either the java.sql.Connection or javax.transaction.UserTransaction interface. These are the same interfaces that a session bean with bean-managed transactions may use. Transactions demarcated with the Connection interface are discussed in the section JDBC Transactions (page 324) and those with the UserTransaction interface are discussed in the section JTA Transactions (page 325). For an example of a Web component using transactions, see Accessing Databases (page 221).
