Recommended Learning routes for J2EE

Many materials are provided on the Internet and in the bookstore, and J2EE information can be obtained in many ways. The question of how to systematically and efficiently learn J2EE is in front of us. For example, some people still don't know how to start when they get started after reading a bunch of books. And so on. How can we find a good method?
In fact, from another perspective, for example, to learn English, there are three levels of things: vocabulary, grammar, furthermore, it is a habit of usage (I hope readers can consider the problem from the perspective of programming and see what similarities are between the two. In fact, their logic is the same ). For example, when I was in a math class and the teacher solved the problem on the blackboard, everyone could easily understand it and there would be a lot of problems when I started my own work. These seemingly simple problems actually contain the following principle:
Linking theory with practice and guiding practice.
Our theory is that we need to have a good method. Some people read a lot of books and write a lot of programs. The level of improvement is still very slow and it is difficult to overcome this challenge. Or method problems. Of course, the methods I have talked about are my own experiences and experiences. Everyone has their own unique methods. There is no absolutely good or absolutely bad method to see who is the target object. So here we will focus on the methods I will propose in this article. Let's comment.
In the previous article (a long journey towards J2EE), I talked about the process of learning J2EE. Because it contains a lot of new things. In addition, J2EE is currently in progress. We know that J2EE is composed of many technologies, such as EJB, XML, JDBC, RMI, JSP, Servlet ,.... And so on.
Regardless of how these technologies develop and change, we need to grasp the main line, that is, to grasp the essence of the J2EE architecture. What to use to analyze it, the role of the object is naturally J2EE Specification (the latest version is 1.4, http://java.sun.com/j2ee )!!! Of course, the premise for learning J2EE is that you are familiar with J2SE, and you have a good attitude and interest. It is not enough to look at the J2EE specifications. It is best to consider it in combination with products and examples. I suggest using JBuilder 7 + BEA WebLogc Platform 7.0, this development mode. Why? First of all, JBuilder 7 has good functions and should be a mainstream Java IDE. Second, BEA WebLogic Platform 7.0 has good support for the latest J2EE Specification version, and is also easy to obtain. Many users are also using it. Third, the development efficiency is good. (Borland website has a document about JBuilder 7 + BEA WebLogic 7.0 integrated development. PDF format. Http://bdn.borland.com/article/0,1410,28943,00.html)
