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. 回答1: I recommend Bitronix. Before using any other transaction manager, I recommend thorough testing. Tests like killing power to various

#0 系列目录# 分布式事务 【分布式事务系列】提出疑问和研究过程 对于我们这种初学者，可能会使用Spring带给我们的@Transactional，可能了解JTA，可能会使用jotm、atomikos，又会遇到一些名词XA，支持XA的数据库驱动等等诸多问题，然后就会愈加混乱，自然形成一个疑问，庞大的事务体系的全貌到底是什么样？ #1 需要解决的疑惑# 下面就要具体列出一系列需要解决的问题。 ##1.1 对于事务模型## 三种事务模型是什么？各自的特点是什么？各自的缺陷是什么？ ##1.2 Spring对于事务模型的支持## Spring自己的一系列接口设计： PlatformTransactionManager 事务管理器 TransactionDefinition 事务定义 TransactionStatus 事务状态 等等 上述一系列接口的实现是如何对非分布式和分布式事务的支持的呢？ ##1.3 针对分布式事务的规范## X/Open DTP模型是什么？几个重要的概念是什么？ XA规范是什么？ 2PC是什么？ ##1.4 针对JTA## JTA是什么？JTS又是什么？ JTA与上述的规范又是什么关系？ JTA的接口都有哪些？分别是什么作用 JTA接口中有一个javax.transaction.TransactionManager

How to use JTA support in Tomcat 6 for Hibernate?

由 给你一囗甜甜゛ 提交于 2019-11-27 06:45:42
They recommend using JTA transaction support in Java EE environment. But how to configure JTA in Tomcat6 so that Hibernate Session could use it ? Starting with version 3.0.1, Hibernate added the SessionFactory.getCurrentSession() method. Initially, this assumed usage of JTA transactions, where the JTA transaction defined both the scope and context of a current session. Given the maturity of the numerous stand-alone JTA TransactionManager implementations, most, if not all, applications should be using JTA transaction management, whether or not they are deployed into a J2EE container. Based on

Difference between a “jta-datasource” and a “ resource-local ” datasource?

由 狂风中的少年 提交于 2019-11-27 05:58:20
The terms "jta-datasource" and "resource-local datasource" are a little vague to me. I'm putting down what I am understanding ( or assuming ) and I'd like you to say where I'm right / wrong. The same database can be referred to as a jta-datasource or as a resource local datasource If mentioned as jta-datasource, then the beans / other classes can use JTA. Hence, UserTransaction interface Cannot use CMT / BMT if the datasource is resource local If mentioned as resource local datasource, transactions are not JTA aware. Code can use EntityTransaction interface but not UserTransaction interface

persistence.xml different transaction-type attributes

由 只谈情不闲聊 提交于 2019-11-27 05:56:21
In the persistence.xml JPA configuration file, you can have a line like: <persistence-unit name="com.nz_war_1.0-SNAPSHOTPU" transaction-type="JTA"> or sometimes: <persistence-unit name="com.nz_war_1.0-SNAPSHOTPU" transaction-type=”RESOURCE_LOCAL”> My question is: What is the difference between transaction-type="JTA" and transaction-type=”RESOURCE_LOCAL” ? I also noticed some persistence.xml files with the transaction-type missing. Is it correct? Defaults Default to JTA in a JavaEE environment and to RESOURCE_LOCAL in a JavaSE environment. RESOURCE_LOCAL With <persistence-unit transaction-type=

javax.transaction.Transactional vs org.springframework.transaction.annotation.Transactional

由 心不动则不痛 提交于 2019-11-27 03:08:07
I don't understand what is the actual difference between annotations javax.transaction.Transactional and org.springframework.transaction.annotation.Transactional ? Is org.springframework.transaction.annotation.Transactional an extension of javax.transaction.Transactional or they have totally different meaning? When should each of them be used? Spring @Transactinal in service layer and javax in DAO? Thanks for answering. Spring has defined its own Transactional annotation to make Spring bean methods transactional, years ago. Java EE 7 has finally done the same thing and now allows CDI bean

Hibernate session.close() not returning connection to pool

由 人走茶凉 提交于 2019-11-27 02:41:31
问题 My application has long running transactions and hence I tried the option session.close() at the end of every method to ensure that the connection objects are not held indefinitely for long time. When session.close() option is used, I could see that the Hibernate's session object and the corresponding Connection object obtained from session.connection() are destroyed properly. But the issue is with the connection pool. The connection obtained by the session is not released back to the
