问题 I was stuck in very hard situation for a moment.

问题 I'm trying to set-up Bitronix in Spring Boot to use last resource gambit with non-XA datasource. Of course by default (autoconfiguration) data source does not participate in XA transaction. It seems that org.springframework.boot.jta.XADataSourceWrapper will work only for XADataSource . How to connect DataSource with Bitronix? 回答1: Bitronix uses its LrcXADataSource to implement the last resource gambit. You need to tell Spring Boot to create an XAResource of that type: spring.datasource.xa

问题 Within JBOSS 7.1 AS, I'm using container managed transaction. For each request, I do several entity updates. Most of the entities use "insert, merge, refresh" methods from EntityManager to manage the updates. However, there is one entity that uses explicit Query to do "executeUpdate" on the DB (see below for the code snippet). This sql update is immediately commited to the DB and it is not aligned with container managed transaction (like other entity updates). Is there anyway align explicit

问题 I am running Glassfish 3.1.1 with an Oracle database and have run into an issue with transactions not rolling back, but only on one specific environment so far. The same application works as expected on other machines. However, two separate Glassfish domains on the same machine are impacted. Within the affected environment, I have similar results with both a container-managed transactions (CMT) inside an EJB that throws a RuntimeException, and a bean-managed transaction (BMT) with

问题 I have a web-app, which I deploy on Tomcat 6 and it uses Hibernate. It receives messages on a JMS queue which trigger changes both to my DB, via Hibernate and to an Object of mine ( Agent ). The web-requests also access the DB, via Hibernate, and access the shared object (there's a ConcurrentHashMap<AgentId,Agent> held by a singleton). My problem is that I have a JMS message which changes several different Agent s and several tables and I need the changes in the Agent s to be available if and

问题 I have a JTA transcation which I commit. Can I roll it back after I commit? If yes, how? I have following situation. I have a backend layer which updated 3 DBs. I have used JTA user transcation for it. If update in any DB fails all updates to 3 DBs are rolled back using utx.rollback Now I have a layer on top of backend layer which updates some other DB. Now I want that step 1 and step 2 should both succeed or both fail, so I want to roll back JTA transcation of step 1 in case step 2 fails. It

问题 I'm quite new to Java EE, and I have set up a project using NetBeans 8.0. In my EAR project, I created a JDBC DataSource and ConnectionPool which are successfully deployed to the Glassfish server upon deployment. When I try to connect I am using JPA 2.1 with Hibernate 4.3.5 and I am using the JTA jta-data-source entry in my persistence.xml file to name the managed resource. My persistence.xml file is as follows: <?xml version="1.0" encoding="UTF-8"?> <persistence version="2.1" xmlns="http:/
