一个MySql ,一个 Oracle92, EJB 布署上去正常,自动创建表结构,当同时向两个数据库插入数据时服务器异常如下:
02:02:07,531 WARN [loggerI18N] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.disallow] [com.arjuna.ats.internal.jta.transaction.arjunacore.lastResource.disallow] Adding multiple last resources is disallowed.

------解决方案--------------------
“同时向两个数据库”
这个具体讲下，
connection都不一样，如何“同时”，不解，
------解决方案--------------------
mysql从5.0开始支持XA DataSource。Connector/J 版本要使用5.0版本，5.0以下的不支持。
