问题 I'll try to configure spring with hibernate using JTA and I have this spring xml file: model.xml <beans> <bean id="txManager" class="org.springframework.transaction.jta.JtaTransactionManager"> <property name="transactionManagerName" value="java:/TransactionManager" /> <property name="userTransactionName" value="UserTransaction" /> <property name="allowCustomIsolationLevels" value="true" /> </bean> <tx:annotation-driven transaction-manager="txManager" /> <jee:jndi-lookup id="dataSource" jndi

问题 (Please feel free to edit the title after reading this question) I have quite simple @ManyToOne bidirectional mapping between entities Parent and Child . The list of children Collection<Child> children in Parent is never initialized so it should be null . When using EntityManager.find(...) for previously persisted Parent and then getting the list from that Parent gives ArrayList even there are no children yet with this Parent and it is fine. However if persisting or merging a new Parent in

问题 It feels so simple: I have a ViewScoped bean (JPA2 + EE6 + Seam3, if that matters) where the user of the web application can invoke a method like this: public void save() { doEntityManagerStuff(); // manipulates data in the database callRemoteWebservice(); // which is to read said data and propagate it to other systems } Unfortunately, save() starts a transaction at the opening curly bracket and doesn't commit it before the closing bracket , meaning that the new data is not available to the

问题 I'm a java beginner. I'm in trouble to configure a persistance unit using JTA transactions. I need to use a PostgreSQL database that is already defined, configured and populated. Using netbeans, i created the persistance.xml and glassfish-resources.xml as fallows: <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence

问题 I am reading the book Pro Spring 3 and in the chapter about Global Transactions there is some example code for persisting an object into two different mysql schemas. I am running the code but the object is not saved in any of the two schemas. Here is the code. tx-jta-app-context.xml : <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema

问题 It'll be weeks that I'm stuck with EclipseLink. I can not persist an object in my database. I use netbeans 7.3. I encountered this problem when I started designing a web application. What follows is the approach I have adopted. It may be that I do without me realize a mistake. After that netbeans has finished generating the project files I configured the jndi. Then I converted automatically with netbeans, the database tables in entity object. here is the link then, from these classes, I

问题 The Problem I am getting the following exception when trying to update records in my database: java.lang.UnsupportedOperationException at org.hibernate.service.jta.platform.internal.WebSphereExtendedJtaPlatform$TransactionManagerAdapter.setRollbackOnly(WebSphereExtendedJtaPlatform.java:139)....

Weird Twist We are required to use MyEclipseBlue and that Maven or ant
