This is a very general question to answer, but here is the order that I would learn:
Learn about how the server works. The simplest one would probably be looking at Apache Tomcat. This would serve as the basis for other Java EE Application servers
Next you need the basics on how a Java EE server accepts a request and gives a response. This would be the Servlet as well as Java Server Pages(JSP).
Java Beans is fundamental for Java EE. It represents the object model that you will use across the application
If you are interested in messaging, you should familiarize yourself with JMS
To connect to various databases, you need to know how to use JDBC. The tutorial will get you up and running pretty soon
Once you learn those, there are a few frameworks that people use in the Java EE world. You could pick and choose once you have understood the basics. Few example of well known frameworks:
Hibernate is well known ORM framework for Java enabling further abstraction over JDBC
Apache Strut provides a framework for developing MVC app. Note, that people normally choose between Spring Framework MVC or Strut. You are welcome to learn both
JavaServer Faces(JSF) is yet another option for building your application. I have not used this one personally
There are many other frameworks out there for building Java EE applications. You should get to know the basics and then pick and choose which framework that you want to learn to extend the basics. I, by no means, have not put every single framework in the options, but it should be enough to get your started
As for books, there is no single book out there that covers all options but the core of Java EE is available to buy/download/view online. You could get them at Java EE Tutorial or as printed book That should give you plenty to learn initially. Another book that people are recommending is Head First Servlets and JSP

这是一个非常普遍的问题，但我要学习的顺序如下：
还有许多其他框架可用于构建 Java EE 应用程序。您应该了解基础知识，然后选择您想要学习的框架来扩展基础知识。我绝不是没有将每个框架都放在选项中，但它应该足以让您入门
至于书籍，没有一本书涵盖所有选项，但可以购买 Java EE 的核心/下载/在线查看。您可以在 Java EE 教程 或 作为印刷书籍 这应该会让您一开始就学到很多东西。人们推荐的另一本书是 Head First Servlets and JSP
