How to keep a UserTransaction through many requests
Issue
- Is it possible keep a UserTransaction through many requests in a CDI/JSF application (WAR)? Below is a simple CDI application deployed on JBoss EAP 6.
- Bean class:
@Named
@ConversationScoped
public class TestBean implements Serializable {
@Inject
private UserTransaction userTransaction;
@Inject
Conversation conversation;
protected Logger log = Logger.getLogger(TestBean.class);
public void begin() throws Exception{
conversation.begin();
try {
userTransaction.begin();
} catch (Exception e) {
e.printStackTrace();
}
logStatus();
}
public void doSomeAction() throws Exception{
log.info("Doing some action...");
logStatus();
}
private void logStatus() throws Exception {
log.info("Conversation: " + conversation.getId());
log.info("Transaction status: " + userTransaction.getStatus());
}
}

- Log output:
Transaction status 0 => ACTIVE
Transaction status 6 => NO_TRANSACTION

-
At that point the transaction should have the status 1 instead of 6.

We are getting the below error repeatedly and consistently in our logs :
