I store file’s attributes (size, update time…) in database. So the problem is how to manage transaction for database and file. In a Java EE environment, JTA is just able to manage database transaction. In case, updating database is successful but file operation fails, should I write file-rollback method for this? Moreover, file operation in EJB container violates EJB spec. What’s your opinion? Access to external resources such as a file system should ideally go through a JCA connector . Though there are several posts around discussing this, I never found a ready-to-use JCA connector for

Basically, what it says on the tin; I need a JTA implementation useable in a Java SE application, ideally one that doesn't carry too much of a framework burden with it. erickson I recommend Bitronix . Before using any other transaction manager, I recommend thorough testing. Tests like killing power to various machines during each phase of the transaction. You want transactionality to protect you when failures occur. It is surprising how many transaction managers have failed to correctly implement recovery. Bitronix does need JNDI, which is typically provided for you in a Java EE container, but

I think this is a fairly common question: how to put my business logic in a global transaction in distributed systems environment? Cite an example, I have a TaskA containing couples of sub tasks: TaskA {subtask1, subtask2, subtask3 ... } each of these subtasks may execute on local machine or a remote one, I hope TaskA executes in an atomic manner(success or fail) by means of transaction. Every subtask has a rollback function, once TaskA thinks the operation fails(because one of subtask fails), it calls each rollback function of subtasks. Otherwise TaskA commits the whole transaction. To do

Can anybody explain what is difference between : @Resource UserTransaction objUserTransaction; and EntityManager.getTransaction(); And also what is container managed transaction? and how should I do it in my session facade if I want to insert three rows in table in transaction. ewernli EJB are transactional components. The transaction can be managed either by the applicaiton server itself (CMT - container-managed transaction), or manually by yourself within the EJB (BMT - bean-managed transaction). EJB supports distributed transaction through the JTA specification. The distributed transaction

概念 java事务API(Java Transaction API,简称JTA)是一个Java企业版的应用程序接口。不过JTA只是提供了一个接口，并没有提供具体的实现。 常见的JTA实现如下 J2EE容器所提供的JTA实现(JBoss) 独立的JTA实现:如JOTM，Atomikos 二阶段提交协议 将各个库视为参与者,而将分布式事物管理器视为协调者 协调者对各参与者发起预提交请求 各参与者预提交后向协调者确认可以提交 协调者再对各参与者发起提交请求 各参与者提交事务,并向协调者确认提交成功 上述期间任何错误,都有可能造成各库数据全部回滚 三阶段提交协议(两阶段提交的升级版) JTA的缺点 实现复杂,通常情况下,JTA UserTransaction需要从JNDI获取 JTA本身就是个笨重的API 通常JTA只能在应用服务器环境下使用，因此使用JTA会限制代码的复用性 JTA在实际开发中并不常用,业内主要采用MQ等异步方式解决一致性问题 来源： https://blog.csdn.net/xuanyuanjiaqi/article/details/100045164

I switched from Hibernate 4.2 to Hibernate 4.3 and my project is not working any more. I'm getting an HibernateException: Unable to locate current JTA transaction when I do Session s = sessionFactory.getCurrentSession(); I've realized that org.hibernate.transaction.TransactionManagerLookup does not exist any more.
