Hello,
I am trying to get transaction support for my JPA project. I get this
error:
Caused by: org.apache.openjpa.persistence.TransactionRequiredException: Can
only perform operation while a transaction is active.

My Blueprint XML is:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:jpa="http://aries.apache.org/xmlns/jpa/v2.0.0";
xmlns:tx="http://aries.apache.org/xmlns/transactions/v1.2.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0
https://osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";>
<jpa:enable />
<tx:enable-annotations />
<bean id="userService" class="org.data.service.impl.UserServiceImpl"/>
<service ref="userService" interface="org.data.service.UserService" />
</blueprint>
My Service:
import static javax.transaction.Transactional.TxType.REQUIRED;
import static javax.transaction.Transactional.TxType.SUPPORTS;
import javax.transaction.Transactional;
...
@Override
@Transactional(REQUIRED)
public void updateUser(User user) {
em.persist(user);
em.flush();
}
Log file shows the interceptor:
48 - org.apache.aries.transaction.blueprint - 1.1.1 | Component
userService.addUser is txType Supports.
48 - org.apache.aries.transaction.blueprint - 1.1.1 | PreCall for bean

Any idea how to make it work or troubleshoot this?
Versions:
org.apache.aries.transaction.blueprint: 1.1.1
org.apache.aries.jpa.blueprint: 2.6.1
OpenJPA: 2.4.2
Thanks in advance
