You can be a Java EE expert but still fall flat on your face if you don't get the business logic. Having said that, the whole business of differentiations of the Java platform is awkward and unfortunate. In order to do many "standard" things with Java you actually need Java EE libraries. I don't know the exact history, but I can see a few marketing dudes at Sun back in the day embracing the "enterprise" buzzword, and deciding that such and such APIs were enterprise-y...which is meaningless actually. If you want to do serious work with Java you cannot not do Java EE. Unless you're really niche. And quite frankly, for most Java developers the amount of Java EE APIs they need to master is a small percentage of the whole. Differentiate specs from vendor implementations. It's the latter that can cost a lot. But as others have said, there are a number that you can get free of charge. You might think of Java EE as providing support for applications that run on a server that runs on a JVM, where the server is contractually obligated to provide a large number of facilities to the hosted apps. In comparison, a non Java EE app largely fends for itself, and runs directly on a JVM.
