	 * Gets called by <code>SqlMapClientTemplate.execute with an active
	 * <code>SqlMapExecutor. Does not need to care about activating
	 * or closing the <code>SqlMapExecutor, or handling transactions.
	 *
	 * <p>If called without a thread-bound JDBC transaction (initiated by
	 * DataSourceTransactionManager), the code will simply get executed on the
	 * underlying JDBC connection with its transactional semantics. If using
	 * a JTA-aware DataSource, the JDBC connection and thus the callback code
	 * will be transactional if a JTA transaction is active.
	 *
	 * <p>Allows for returning a result object created within the callback,
	 * i.e. a domain object or a collection of domain objects.
	 * A thrown custom RuntimeException is treated as an application exception:
	 * It gets propagated to the caller of the template.
	 *
