See JDK 7 and JRE 7 Installation Guide for general information about installing JDK 7 and JRE 7.

The following enhancements have been introduced. They are listed by platform.

• Oracle Solaris OS
• Microsoft Windows
• Linux

Oracle Solaris OS

Area: Installer
Standard/Platform: JDK 7
Synopsis: As of the Oracle Solaris 11 Express release, the IPS packaging system is the new default mechanism for installing, upgrading, and removing software packages. The JDK 7 release supports the IPS system. IPS packaging introduces change to all users of Solaris. Every package will likely have a name change and process change. Automated installers and install verification applications written by users or third parties will require updating.

Microsoft Windows

Area: Installer
Standard/Platform: JDK 7
Synopsis: Need to truly integrate JavaFX into the JRE/JDK Installers
Installers for JDK 7u6 and later install the JavaFX SDK and integrate it into the JDK installation directory. Installers for JDK 7u2 to 7u5 install the JDK first, then start the JavaFX SDK installer.
Installers for JRE 7u6 and later install the JavaFX runtime and integrate it into the JRE installation directory. Installers for JRE 7u2 to 7u5 install the JRE first, then start the the JavaFX runtime installer.
If you want to install the JavaFX SDK or JavaFX runtime (version 2.0.2) with JRE 7u1 or earlier, see Installing JavaFX for more information.
