Everyone who is interested in Oracle Fusion Middleware probably knows, JDeveloper 11g is production now. And its possible to install it on Mac OS as well. On Windows, installation process is more straightforward, however it is relatively easy on Mac OS also - just you will need to follow a couple of configuration steps. In this post I will give instructions, I was following in order to install JDeveloper 11g on my MacBook Pro, I will concentrate on those instructions not mentioned in installation guide.
Installation process steps:
1) Download jdevstudio11110install.jar from OTN download page. It is a base install, without JDK 6.
2) Go to Oracle Fusion Middleware Installation Guide for Oracle JDeveloper on OTN and follow listed instructions.
3) After you will install Sun Java SE 6 for Mac OS X 10.5, you will need to make Java 1.6.0 default version of Java on your machine. You must run Java Preferences utility at /Applications/Utilities/Java/ to make Java 1.6.0 the default version on your OS. But, this will not change Java version across all system, so in terminal window I executed following commands as a root user to make Java 1.6.0 default VM:
$ cd /System/Library/Frameworks/JavaVM.framework/Versions/
$ ls -l CurrentJDK
lrwxr-xr-x 1 root wheel 5 Oct 3 21:33 CurrentJDK -> 1.5.0
$ sudo rm CurrentJDK
$ sudo ln -s 1.6.0 CurrentJDK
lrwxr-xr-x 1 root wheel 5 Oct 3 21:40 CurrentJDK -> 1.6.0
Now if you will execute java - version in terminal window, you should get something similar:
java version "1.6.0_05"
Java(TM) SE Runtime Environment (build 1.6.0_05-b13-120)
Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_05-b13-52, mixed mode)
4) However, if you will run JDeveloper 11g installer at this step, you still will not be able to install successfully. In my case, installer wasn't able to find Java Home, even if I was providing it directly. I have solved this, when I have found a section about Known Issues for installing JDeveloper 11g on Mac OS in Release Notes document.
When all listed steps were done, installation wizard found Java 1.6.0 automatically and installation finished successfully:
JDeveloper 11g is up and running on Macintosh:
