关于Java SE和Java EE的困惑 [英] Confusion about Java SE and Java EE
问题描述
我正在愉快地使用Java SE和Eclipse，但现在我要编写一个发送邮件程序，该程序需要 javax.mail 包。我发现在Java EE中我下载了一个（180MB），我知道Java EE安装需要SE JDK / JRE。因为我在 c：\ java \ _jdk1.7 （不是默认路径）中安装了Java SE，所以我使用 -jc：\ javaa \\ jdk1.7 安装Java EE。我有几个问题。
I am using Java SE with Eclipse happily but now I am going to write a "send mail" program which requires javax.mail package. I found that in Java EE so I downloaded one (180MB) and I know that Java EE installation needs SE JDK/JRE. Because I installed Java SE in c:\java\jdk1.7 (not the default path) I use -j c:\java\jdk1.7 to install Java EE. I have several questions about it.

我怎样才能让Eclipse加载Java EE包？我应该在Java EE中更改JRE吗？现在Eclipse仍然只知道SE库。
How could I let Eclipse to load the Java EE package? Should I change the JRE in Java EE? Now Eclipse still only know the SE lib.
我们是否有一个包含Java EE API的JDK版本？因为我真的不想在我的电脑上安装两个JRE而且我不需要Glassfish。有人可以告诉我应该下载哪一个吗？
Do we have a JDK version which include APIs from Java EE? Because I really do not want to install two JREs in my computer and I do not need Glassfish. Can some one tell me which one I should download?
Java EE是否有 src.zip API？我找不到它。
Is there src.zip for Java EE api? I cannot find it.
