What's the relation between Java EE and Grails

I'm taking a course named "Developing distributed application with JEE". They asked us to develop an application using Grails and Groovy. I'm a little confused, what's the relation between Java EE and Grails?

For me they are different frameworks like Django, Ruby on Rails...etc.

Often people think of EJBs when they think of Java EE, but that's just one of several of the technologies used in Java EE. Grails supports or uses several Java EE technologies directly (including the Servlet API, JSPs, JSTL, transactions (JTA), JPA, etc.), and others are available via plugins (e.g. WebSockets, JMS, JAX-RS, etc.)

Grails uses Spring, so instead of using CDI for dependency injection, it uses Spring's DI support. Spring has excellent integration for many Java EE technologies, so using EJBs and other Java EE APIs would be straightforward by leveraging Spring for those.

Additionally, deploying a Grails application is the same as for any other servlet-based application - you create a WAR file and deploy it to a servlet container or application server. There are also scripts available to package a Grails application in an EAR file if necessary.
