20: * Exception to be thrown when a transaction has timed out.
21: *
22: * <p>Thrown by Spring's local transaction strategies if the deadline
23: * for a transaction has been reached when an operation is attempted,
24: * according to the timeout specified for the given transaction.
25: *
26: * <p>Beyond such checks before each transactional operation, Spring's
27: * local transaction strategies will also pass appropriate timeout values
28: * to resource operations (for example to JDBC Statements, letting the JDBC
29: * driver respect the timeout). Such operations will usually throw native
30: * resource exceptions (for example, JDBC SQLExceptions) if their operation
31: * timeout has been exceeded, to be converted to Spring's DataAccessException
32: * in the respective DAO (which might use Spring's JdbcTemplate, for example).
33: *
34: * <p>In a JTA environment, it is up to the JTA transaction coordinator
35: * to apply transaction timeouts. Usually, the corresponding JTA-aware
36: * connection pool will perform timeout checks and throw corresponding
37: * native resource exceptions (for example, JDBC SQLExceptions).
