我遇到了在WebSphere 7上部署的restful Web服务的问题。每次我尝试访问url时都会收到以下错误消息：
"WLTC0017E: Resources rolled back due to setRollbackOnly() being called".
我怀疑我的间接查找是导致问题的原因。我有我这样的查找代码
try {
this.em = (EntityManager) new InitialContext().lookup("java:comp/env/persistence/BACPOnlineAPPPU);
this.utx = (UserTransaction) new InitialContext().lookup("java:comp/UserTransaction");
} catch (NamingException ex) {
throw new RuntimeException(ex);
}
除此之外，我已经创建了我的数据源并使用WebSphere成功测试。我做错了什么恶事？
这是我的堆栈跟踪：

您很可能会看到事务超时。您应该做的是确保您的应用程序提交更改。您还可以增加WAS的数据库超时。您可以在“交易服务”下找到它们。
