I have been trying to install JDeveloper Suite 121200 on my MacBook Air running OSX 10.8.5 Mountain Lion for a couple of days but have not succeeded.
I have read every install guide I've been able to find, but still haven't been able to make it work.
Does anybody have any advice for me, I really need to install this to be able to do the assignments we get from school.
Thanks in advance,
just installed the same yesterday with no problem. Make sure you download the Generic Installer (aka the JAR installer). Then install Java 7 to your MAC and ensure its the default Java version (type java -version on the terminal). Then call java -jar <jdeveloper install file name>.jar from the directory you copied the downloaded files to (by default this is called "Download"). Wait for the installer to pop up (may take a minute) and then install JDeveloper. The install directory then has a JDeveloper / JDev folder that contain the start icon to use for starting the IDE
