Why include javax.Transaction?

What is the purpose of including compile 'javax.transaction:jta:1.1' in the Gradle dependencies? From what I can tell from examining the beginTransaction() method in IntelliJ, it is from the org.Hibernate.Session class. I'm also confused as to why there wouldn't be something like import javax.Transaction; included. Maybe I missed something in the video but it would be great if someone could explain.

Take a look at the teacher's notes behind the video: https://teamtreehouse.com/library/hibernate-basics/persisting-data-with-hibernate/saving-data-with-hibernate

Chris says that this transaction library will be used in runtime, not during compile. So there is no import statements, but you should get an error I guess when you use transaction in your app without this dependency. I tried without this library and it worked anyway, but I think for that we should ask Chris for more explanation.
