Installing Oracle JDeveloper 11.1.1.6.0 on Mac OS X 10.8.2 Mountain Lion

1. Take care: Version Oracle JDeveloper 11.1.1.6.0 is not Version Oracle JDeveloper 11.1.1.6.0 !
There are more than one Version of Oracle JDeveloper 11.1.1.6.0
Both start with  Oracle JDeveloper 11.1.1.6.0

The latest version has *CLOUD* within the Version Title.
If you want to try Oracle Cloud, than you need to download this version in order to have the cloud connection availabe within the database navigator.

2. Download the Oracle Software:So you might want to download the latest Version 11.1.1.6.0.
(Although a Version Oracle JDeveloper 11g (11.1.2.3.0) (Build 6276.1) is availabe, this Version is not suitable if you want to build SOA, BPM, WebCenter or Oracle Cloud applications.
Download Oracle JDeveloper 11.1.1.6.0:
http://www.oracle.com/technetwork/developer-tools/jdev/downloads/jdeveloper11116-1377208.html

3. Install Oracle JDeveloper 11.1.1.6.0
ATTENTION: This not trivial as well. If you try to install Oracle JDeveloper 11.1.1.6.0 with JDK 1.7.x it will fail with error: "A fatal error has occurred.  This application will terminate."

So we need to start the installation with JDK 1.6.x.
But: you might kbow, that the responsibility for Java has been moved from Apple to Oracle...

Start your terminal.
java -version

java version "1.7.0_13"
Java(TM) SE Runtime Environment (build 1.7.0_13-b20)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

Now we create a dummy folder with a symbolic link:
sudo mkdir -p /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/jre/lib

cd /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/jre/lib/

sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/classes/classes.jar rt.jar

Now we set the environment to Java 1.6.x:

export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
export PATH=$JAVA_HOME/bin:$PATH

Now check the java version, again:
java -version

java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

Perfect.
Now we can navigare to the download folder and start the installer:
java -jar jdevstudio11116install.jar

Your Oracle JDeveloper 11.1.1.6.0 install shoud be successful.

And now you should also be able to see the cloud connection option in the Database Navigator:

Enjoy!
