Spring + Eclipselink + JtaTransactionManager = javax.persistence.TransactionRequiredException - spring

Question

I really hope you can help me. I've been looking all over the internet for answers and none of them works.
I use Spring 3 + JTA + EclipseLink but i'm getting a TransactionRequiredException when flushing a transaction. Now i'm very used to just defining my persistence context and injecting the EntityManager and the transaction is handled by the app server.
So here's what I've got.
persistence.xml

}
So here's the deal, when I uncomment the transactionManager parts, the program operates as expected, which is I can see the insert statements. However, when using the above code, I get the following stacktrace :

So as you can see, it connects correctly to the database, and it "persists" the data, but never actually execute the insert statement. Then when flushing the EM, it throws the exception.
Your help will be greatly appreciated.
Best Regards.

Answer 1

Ok, so I figured out how to get this working 100%.
First of all, I don't have to define any persistence(context/unit) in web.xml. Next I removed the transactionmanager and the entityManagerFactory beans. Also removed the context:driven line.
I also made my "beans" Stateless session beans. I then instantiate it through spring through jndi context lookups. This autowires the entitymanager exactly as i want it. No more worrying about transactions, the app server handles that.
so my final config is :
spring-config.xml :
<jee:jndi-lookup jndi-name="java:global/Cartouchan-Web/CategoryController" id="categoryController"/>
<jee:jndi-lookup jndi-name="java:global/Cartouchan-Web/UserController" id="userController"/>
<bean id="applicationContextProvider" class="com.cartouchan.locator.beans.CustomApplicationContext"></bean>
<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor" />
bean sample:
import java.text.MessageFormat;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import org.apache.log4j.Logger;
#Stateless
public class CategoryController {
private static final Logger logger = Logger.getLogger(CategoryController.class);
#PersistenceContext
private EntityManager entityManager;
public CategoryController() {
// TODO Auto-generated constructor stub
}
public boolean createCategory(final String name) {
boolean result = false;
try {
com.cartouchan.locator.database.models.Category category = new com.cartouchan.locator.database.models.Category();
category.setName(name);
entityManager.persist(category);
entityManager.flush();
result = true;
} catch (Exception ex) {
logger.error(MessageFormat.format("Could not create the category {0}", name), ex);
}
return result;
}
public boolean updateCategory(final int id, final String name) {
boolean result = false;
try {
com.cartouchan.locator.database.models.Category category = getCategory(id);
category.setName(name);
entityManager.merge(category);
entityManager.flush();
result = true;
} catch (Exception ex) {
logger.error(MessageFormat.format("Could not update for the category {0} -{1}", id, name), ex);
}
return result;
}
public boolean deleteCategory(final int id) {
boolean result = false;
try {
com.cartouchan.locator.database.models.Category category = getCategory(id);
entityManager.remove(entityManager.merge(category));
entityManager.flush();
result = true;
} catch (Exception ex) {
logger.error(MessageFormat.format("Could not delete for the category {0}", id), ex);
}
return result;
}
public com.cartouchan.locator.database.models.Category getCategory(final int id) {
return (com.cartouchan.locator.database.models.Category) entityManager.createQuery("select p from Category p where p.id=:id").setParameter("id", id).getSingleResult();
}
public List<com.cartouchan.locator.database.models.Category> getAllCategories() {
return (List<com.cartouchan.locator.database.models.Category>) entityManager.createQuery("select p from Category p").getResultList();
}
}
Then to use the bean, just do a standard spring lookup of the bean. Easy as pie.

Answer 2

In order to use JTA transactions managed by the application server you need to use EntityManagerFactroy created by the application server itself.
I.e. you need to remove your LocalContainerEntityManagerFactoryBean declaration and obtain EntityManagerFactory from the application server via <jee:jndi-lookup>. Also you should configure application server to create EntityManagerFactory - see your application server documentation.

Answer 3

property name="eclipselink.target-server" value="WebSphere_7"
set the server type....
hope this one should work..
