title: Confusion about Java SE and Java EE
body: <p>I am using Java SE with Eclipse happily but now I am going to write a "send mail" program which requires <code>javax.mail</code> 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 <code>c:\java\jdk1.7</code> (not the default path) I use <code>-j c:\java\jdk1.7</code> to install Java EE. I have several questions about it.</p>
  
  <ol>
  <li><p>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.</p></li>
  <li><p>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?</p></li>
  <li><p>Is there <code>src.zip</code> for Java EE api? I cannot find it.</p></li>
  </ol>
