I got really excited to hear the news that Oracle JDeveloper 12c released finally.I tried to install the 12c jdeveloper to get my hands dirty but couldn’t even install it :(.
On windows, installer quit abruptly without any error message and on MAC, what the heck happened I don’t even know.Here is the solution to install them successfully on MAC and Windows.
Right click the jdev_suite_121200.exe file and run as Administrator to install.
/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/home/bin/java -jar jdev_suite_121200.jar
Enjoy the 12C release, it has lot of new features but disappointed because there is no ADF mobile support.
