Java EE is basically a collection of API that are shared accross different Java web servers. It's a spec so basically you develop your java app on say glassfish server and you can deploy it on websphere, the servers holds all the libraries you need to run your app, so you can just deploy some small java zip file. Because of trademark issues with Oracle around the name Java, the open source community had to rename all its API jakarta instead of java which is completely stupid and is a demonstration that Oracle is just here to milk the name Java.
