Where is java? Java Control Pannel has disabled "View" button and Terminal still response with "No Java runtime present, requesting install"
Oracle's JRE for OSX does not install all you need for development work. This now means that you do not get /usr/bin/java which in earlier non OSX versions you did. The OSX JRE now provides enough to run Java plugins from your web browser.

If you want to do development you need the JDK currently Java SE 7u40 which is here.
