	        maxOpenPreparedStatements="100"
	        validationQuery="SELECT SYSDATE FROM DUAL" />

</bean>
<bean id="MyDataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
	<property name="jndiName" value="java:comp/env/oracle/call66" />

注：jtom支持分布式事务，多数据源事务，但是在网络断开或者db重起的情况下，不会自动重连。请看相关讨论http://old.nabble.com/Connection-Pool-Recovery-in-Bitronix---migrating-from-JOTM-td22953931.html
