Java EE is enterprise edition.

Includes jsp, servlets, beans, and some other stuff for server programming.

Java SE is standard edition. This is plain old Java. Includes GUI stuff.

blocks|key|1301324|text|Java+SE指的是Java及其库的标准版本。Java是指用于部署web应用程序的Java企业版。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1301325|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Java SE refers to the standard version of Java and its libraries. Java EE refers to the Enterprise edition of Java which is used to deploy web applications.

blocks|key|1516302|text|最大的区别在于企业服务(即ee)，比如支持EJB的应用服务器等。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1516303|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The biggest difference are the enterprise services (hence the ee) such as an application server supporting EJBs etc.

blocks|key|1301491|text|首先，J2SE和J2EE已被重命名。它们现在是Java+SE和Java+EE。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1301492|从本质上讲，Java+SE是为最终用户设计的标准Java。这就是您为桌面应用程序开发的目标。Java是企业版，设计用于服务器编程，例如SOA和web应用程序。|1301493|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

First, J2SE and J2EE have been renamed. They're now Java SE and Java EE.

Essentially, Java SE is your standard Java designed for end-users. That's what you'd develop to for desktop applications. Java EE is the enterprise edition, designed for server programming, such as SOA and web applications.

blocks|key|1516469|text|在Java中，您需要软件来运行程序，就像您已经开发了一个桌面应用程序，并且如果您想要与其他机器共享该应用程序，所有机器都必须安装用于运行该应用程序的软件。但在Java中，不需要在所有机器上安装软件。Java具有转发功能。这只是一个简单的例子。有很多不同之处。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1516470|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

In Java SE you need software to run the program like if you have developed a desktop application and if you want to share the application with other machines all the machines have to install the software for running the application. But in Java EE there is no software needed to install in all the machines. Java EE has the forward capabilities. This is only one simple example. There are lots of differences.

As far as the language goes it is not as though java changes. Java EE has access to all of the SE libraries. However EE adds a set of libraries for dealing with enterprise applications.

Java EE is more like a "platform" or an general area of development.

In Java SE you write applications that run as standalone java programs or as Applets. In JavaEE you can still do this, but you can also write applications that run inside of a Java EE container. The container can do a great amount of management for you such as scaling an application across threads, providing resource pools, and management features.

Java EE has a web framework based upon Servlets. It has JSP (Java Server Pages) which is a templating language that compiles from JSP to a Java servlet where it can be run by the container.

So Java EE is more or less Java SE + Enterprise platform technologies.

Java EE is far more than just a couple of extra libraries (that is what I thought when I first looked at it) since there are a ton of frameworks and technologies built upon the Java EE specifications.

But it all boils down to just plain old java.
