Problem with JTA transactions and OpenJPA

[Stefan Berger]

Hello,

I'm writing a little test application with JSF, CDI, EJB and JPA on JBoss 7. I have a JSF view, the backing bean holds a reference to an EJB which is injected. The EJB gets an EntityManager by injection creates and persists some data. I'm using OpenJPA 2.1.0 with a datasource defined in JBoss 7. The problem is that I always get the error "You cannot set autocommit during a managed transaction", although I do not change the autocommit settings in my code nor do I do any transaction handling in my code. All I do regarding database access is to call em.persist(...):

@Stateless
public class PersistenceEJB 
{
	@PersistenceContext
	private EntityManager em;
	
	public void createPersonObjects(int numPersonObjects) 
	{
		for (int i = 0; i <numPersonObjects; i++)
		{
			Person newPerson = new Person();
			newPerson.setFirstName("xxx");
			newPerson.setSurname("yyy");
			
			em.persist(newPerson);
		}
	}
}

This is my persistence.xml file:
<?xml version="1.0" encoding="UTF-8"?> <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/persistence_2_0.xsd"> <persistence-unit name="RichFacesTest"> <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> <jta-data-source>java:jboss/datasources/PersonDS</jta-data-source> <class>example.richfacestest.persistence.entities.Person</class> <properties> <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO, SQL=TRACE"/> <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)"/> </properties> </persistence-unit> </persistence>

The definition of the datasource in JBoss 7:
<datasource jndi-name="java:jboss/datasources/PersonDS" pool-name="PersonDS" enabled="true" jta="true" use-java-context="true" use-ccm="true"> <connection-url> jdbc:mysql://localhost:3306/persondb </connection-url> <driver> mysql </driver> <pool> <min-pool-size> 10 </min-pool-size> <max-pool-size> 20 </max-pool-size> <prefill> true </prefill> <use-strict-min> false </use-strict-min> <flush-strategy> FailingConnectionOnly </flush-strategy> </pool> <security> <user-name> root </user-name> <password> mysql </password> </security> </datasource> <drivers> <driver name="mysql" module="com.mysql"> <xa-datasource-class> com.mysql.jdbc.jdbc2.optional.MysqlXADataSource </xa-datasource-class> </driver> </drivers>

The stacktrace:
