我的应用程序正在尝试在DB2服务器上的2个数据库上执行分布式事务，app服务器是websphere 6.1并使用Atomikos作为TM。
UserTranaction.commit（）失败，出现以下异常： javax.transaction.RollbackException：事务设置为仅回滚 完整的堆栈跟踪是：

我没有将事务设置为仅在代码中回滚。我猜它默认设置。我想改变它而不是将它设置为rollbackOnly。此外，我在事务后显式调用commit（）。为什么我仍然得到这个例外？我如何确保交易得到承诺？
答案 0 :(得分：0)
解决了这个问题!! 这对我有用：
Voila ......我现在可以提交交易!!
