EJB3定时方法中调用普通数据源方法

需求：需要用EJB3实现定时，定时中需要调用一些数据库truncate操作
现状：EJB3定时在Websphere 中需要使用XA事务，需要使用XA的数据源，而Truncate 操作必须使用普通的数据源，在XA事务调用普通数据源时：[13-8-9 23:25:38:492 CST] 000000c1 WSRdbManagedC W   DSRA0180W: 在执行 ManagedConnection.destroy() 期间检测到异常。异常：com.ibm.ws.exception.WsException: DSRA0080E: An exception was received by the Data Store Adapter. See original exception message: 关闭的连接. with SQL State : 99999 SQL Code : 17008-----------------------------------------------------------------------------------------------------------
