1、事务的bean，id必须为transactionManager吗？为什么我指定为其他名字，然后在<tx:advice id="txAdvice" transaction-manager="myTxManager">指定，还是报错，说no bean names 'transactionManager'？
2、即使我将bean的id命名为transactionManager，还是报错，为：Cannot convert value of type [org.springframework.transaction.jta.JtaTransactionManager] to required type [javax.transaction.TransactionManager] for property 'transactionManager': no matching editors or conversion strategy found
3、使用JOTM配置JTA，是不是一定要用XA连接池（StandardXAPoolDataSource），用dbcp或c3p0可以么？
请指教，谢谢~~
下面是我配置的XML：
