菜鸟请教——websphere中用ibatis事务控制的问题

小弟在web应用程序中使用quartz框架进行job开发，在tomcat上运行没有问题，在was6.0上运行发现如下异常：
[8/12/09 19:59:00:044 GMT+08:00] 0000008c MCWrapper     E   J2CA0081E: Method cleanup failed while trying to execute method cleanup on ManagedConnection [email=WSRdbManagedConnectionImpl@67616761]WSRdbManagedConnectionImpl@67616761[/email] from resource jdbc/scmuat.

看上去像是事务控制问题，我是用的ibatis的事物控制。在运行各个功能模块进行数据的增删改查的时候没有这个问题，一切正常，就是job运行的时候会出现这个问题。
但是异常虽然抛出来了，发现job中执行的增删改查照样还是能够完成的。。。。。。

不知道有没有大虾遇到过这个问题
事物控制都是用的同样的机制，就是ibatis的：sqlmap.startTransaction();和sqlmap.commitTransaction();为何在功能模块执行数据的增删改查和在job中会不一样？
刚开始使用was，望大家能给予指点，谢谢
