First of all, I can't use Spring's @Transactional
annotation. I have to use exactly JTA which in out EJB-container. Currecntly I'm using JBoss AS 7.0 Web-Profile
. So what I need to do is configure Hibernate's session factory to correctly work with JTA
-transaction inside the Spring
's Envirnoment. My current configuration:
piece of the context.xml
configuration:
<tx:annotation-driven/>
<tx:jta-transaction-manager />
<!-- Some other beans -->
<bean id="userTransaction" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/UserTransaction"></property>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="annotatedClasses">
<list>
<value>com.badmitrii.db.entity.Employee</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="userTransaction" ref="userTransaction"></property>
</bean>
DAO-method:
public Player getPlayerById(Integer id){
try {
userTransaction.begin();
} catch (Exception e) { }
//Here is obtaining a Criteria object and setting Restrictions
try {
userTransaction.commit();
} catch (Exception e) { }
return (Player) criteria.uniqueResult();
}
But, I got the following excpetion when I was trying to get Session in the DAO method:
org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:134)

How to configure it correctly?

First of all remove the declaration for JtaTransactionManager
as that is already provided by <tx:jta-transaction-manager />
.
Next there is no reason why you wouldn't be able to use @Transactional
in a JTA environment that is the whole point of declarative tx management.
You should wire the configured jta transactionmanager to the LocalSessionFactoryBean
to switch out the used CurrentSessionContext
.
<tx:annotation-driven/>
<tx:jta-transaction-manager />
<!-- Some other beans -->
<bean id="userTransaction" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/UserTransaction"></property>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jtaTransactionManager" ref="transactionManager" />
<property name="annotatedClasses">
<list>
<value>com.badmitrii.db.entity.Employee</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</prop>
<prop key="hibernate.show_sql">false</prop>
</props>
</property>
</bean>
Then in your cod eyou can simply do something like this
@Transactional
public Player getPlayerById(Integer id){
//Here is obtaining a Criteria object and setting Restrictions
return (Player) criteria.uniqueResult();
}
Update:
For JBoss the <tx:jta-transaction-manager />
doesn't work due to fact that the TransactionManager
for JTA is registered in JNDI under the name java:jboss/TransactionManager
instead of one of the well-known names. You will need to declare the JtaTransactionManager
bean yourself and remove the <tx:jta-transaction-manager />
element. For the lookup you need to specify the transactionManagerName
or do a JNDI lookup yourself.
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManagerName" value="java:jboss/TransactionManager" />
</bean>
The UserTransaction
is registered under the default name so you can omit the injection of it in the JtaTransactionManager
as it will do the lookup itself.
