[JBoss] Which dependency for showing transaction in jboss 7.4: run methods of a @Asynchronous...

I would like to add the following code

try {
Transaction transaction = TransactionManager.transactionManager().getTransaction();
...
} catch (SystemException e) {
throw new RuntimeException(e);
}


I added the dependency:

<dependency>
<groupId>org.jboss.narayana.jta</groupId>
<artifactId>narayana-jta</artifactId>
<version>5.11.3.Final</version>
<scope>provided</scope>
</dependency>


But I get:

java.rmi.RemoteException: Invocation failed; nested exception is:
javax.ejb.EJBException: WFLYEJB0442: Unexpected Error


So how do I do that?

Also: I tried to lookup which version of narayana-jta my jboss uses. How do you do that?

The reason I want to do this is to see if a new transaction is started when I make a session bean @Asynchronous.
