用Spring集成的JOTM配置分布式事务

【藏自】http://boy00fly.iteye.com/blog/1110655

最近项目中涉及到了两个Oracle数据库的操作。需要用到分布式事务,研究之后贴出代码供大家参考。

1.dao-core.xml(核心事务配置XML)

8.特别说明

在项目测试的过程中，有一个错误困扰了我很久，总会报这样的错误

Hibernate: select SN_WONIU.SYS_COMPANY_SQ.nextval from dual
java.sql.SQLException: Cannot get connection for URL jdbc:oracle:thin:@192.168.6.80:1521:C2SServer : 调用中无效的参数

Google了一大圈有不少人碰到这个问题，后来偶是在http://forum.springsource.org/archive/index.php/t-28145.html找到了答案,就是在配置数据源的时候，StandardXAPoolDataSource中要配置user和password，StandardXADataSource中也要配置user和password。 不明白为啥，希望高人不吝赐教。
