New to Java

My system: Windows7 x64 (fresh install - so no previous JRE's or JDK's), Firefox 15.0.1 and IE9

I downloaded this: jdk-7u7-windows-x64.exe
From this page: [http://www.oracle.com/technetwork/java/javase/downloads/jdk7u7-downloads-1836413.html]

I installed the JDK as per instructions on this page: [http://docs.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html]
I updated the PATH environment variable to include: C:\Program Files\Java\jdk1.7.0_07\bin

I restarted the computer.
I checked cmd for java -version, it reports: java version "1.7.0_07" java SE Runtime Environment (build 1.7.0_07-b11) etc...

I tried to view applets in Firefox and IE and they both report that I have to download the Java plugin.
IN Firefox I click "Install plugin" and it looks like it's installing, but then it fails. It then gives me an option to install it manually (which is a link to the Oracle JRE download page.

I did not try that last option because I SHOULD NOT HAVE TO, Oracle's page clearly states [http://docs.oracle.com/javase/7/docs/webnotes/install/index.html] that the JDK INCLUDES the JRE.
"... If you want to develop Java applications, download the Java Development Kit, or JDK. *The JDK includes the JRE, so you do not have to download both separately.*"


Also, it the latest JDK is supposed to come with JavaFX development capabilities, but I don't see JavaFX stuff in any of the Java folders.
