Spring + Hibernate4 + JTA + JBossTS

Question

I have been struggling for more than 2 days, in order to setup JTA with a stand alone Java application, but unfortunately id didn't work, I would appreciate some help.

General Information:

• Spring version: 3.2.3
• Hibernate version: 4.2.3
• Jbossts version: 4.17.7, I added only the narayana-jta.jar to my classpath.

Spring configuration file:

<bean class="com.arjuna.ats.jta.TransactionManager" factory-method="transactionManager" id="arjunaTransactionManager" />
<bean class="com.arjuna.ats.jta.UserTransaction" factory-method="userTransaction" id="arjunaUserTransaction" />

<bean class="org.springframework.transaction.jta.JtaTransactionManager" id="transactionManager">
    <property name="transactionManager">
        <ref bean="arjunaTransactionManager" />
    </property>
    <property name="userTransaction">
        <ref bean="arjunaUserTransaction" />
    </property>
</bean>

<tx:annotation-driven />

Hibernate Configuration File:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD//EN"
  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=TestDB</property>
        <property name="connection.username">user</property>
        <property name="connection.password">password</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">jta</property>

        <!-- Disable the second-level cache -->
        <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
        <property name="transaction.jta.platform">org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform</property>
    </session-factory>
</hibernate-configuration>

At this point I need to create the hibernate session factory, and I want to create it programmatically, to do so I used the following code snippet, where I create a spring LocalSessionFactoryBean pass to it the hibernate configuration resource and retrieve the SessionFactory from it using the .getObject() method.

This code works correctly and creates a SessionFactory object, this object is used in the next code snippet.

LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
JtaTransactionManager trxManager = applicationContext.getBean(JtaTransactionManager.class);
sessionFactoryBean.setJtaTransactionManager(trxManager);
sessionFactoryBean.setConfigLocation(resource);
sessionFactoryBean.afterPropertiesSet();
SessionFactory sessionFactory = sessionFactoryBean.getObject();

After that I have a Service class that does an insert into a TABLE:

package com.core.service;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

@Component
@Scope("prototype")
public class TestService {

    @Transactional
    public void testTrx() throws Exception {
        SessionFactory sessionFactory = // retrieve session factory created before

        Session session = sessionFactory.getCurrentSession();
        Query query = session.createSQLQuery("insert into TABLE1 (col1, col2) values (:v1, :v2)");
        query.setParameter("v1", "value1");
        query.setParameter("v2", "value2");

        query.executeUpdate();
    }
}

And finally a JUnit test that loads the Spring context and initializes everything, and then executes the following lines:

@Test
public void testTransactionRollback() throws Exception {
    TestService testService = applicationContext.getBean(TestService.class);
    testService.testTrx();
}

The Problem: When I execute the JUnit test I get a green bar and I see that there is an SQL statement that inserts into the table, and I see that a transaction is opened and committed, however if I go to the database I don't see the inserted rows.

My Conclusion: I tried to set the hibernate configuration connection.autocommit=true and the row is created in the database correctly, so I assume that Yes JTA transactions are opened and closed but the Hibernate Session Factory is not using them, instead it is using its own. Am I missing some configuration?

Answer 1

I think it is because Your database connection is not bound with JTA. You have only synchronized hibernate with JTA. You should use com.arjuna.ats.jdbc.TransactionalDriver in order to create conenction:

TransactionalDriver arjunaJDBC2Driver = new TransactionalDriver();
Connection connection = arjunaJDBC2Driver.connect(url, dbProps);

spring example:

 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
  <property name="driverClassName">
   <value>com.arjuna.ats.jdbc.TransactionalDriver</value>
  </property>
  <property name="url" value="jdbc:arjuna:mysql://host:3306/dbName"/>
  <property name="connectionProperties">
    <ref bean="dsProps"/>
  </property>
 </bean>

Hope this help
