Installing JDeveloper 11g on Mac OS 10.5

This is actually a guest post - Marc Chanliau from the Oracle Web Service Manager product team sent me a quick email with instructions that he wrote up for installing JDeveloper on a macintosh - and I thought it would make a good blog post that might help people on OTN as well.

 Important Note - an update set of instructions for those installing JDeveloper on Mac Lion OS 10.7 is here.

So here we go with Marc's instructions for:

Installing JDeveloper 11gR1 on Mac OS 10.5 (Leopard)

- Download jdevstudio11110install.jar from OTN (

1. Make Java 6 the default JVM on your Mac
- Run Java Preferences (in /Applications/Utilities/Java)
- Move the Java SE 6 (64 Bit) to the top of the Java application versions

2. In order for the installer to see JKD 1.6 on your Mac, you need to create
a sym link for classes.jar:
cd /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
sudo mkdir jre
cd jre
sudo mkdir lib
cd lib
sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/classes/classes.jar rt.jar

3. Run the JDev installer by clicking on the jdevstudio11110install.jar you
downloaded -- this should automatically start the JAR Launcher and unpack

If you keep all recommended install default values, JDev and ADF are installed
WebLogic Server gets installed at:

4. To start JDev, you can create an alias in your .profile file as follows:
alias startjdev="/users/yourusername/oracle/middleware/jdeveloper/jdev/bin/jdev"


What about the database part? is there a way to have a small Oracle database on my Mac ?

Hussein, Seems like you can get an Oracle to work on Mac OSX see: And remember that JDeveloper can also work with non-Oracle databases if you need to...

Shrinivas, You'll need to install WebLogic 10.3 on your Solaris machine and then follow the deployment instructions from the Fusion Developer Guide. (or from this blog entry: ) )

Shay, the install worked - thanks. I don't see any .profile files for aliases? There's nothing in my user directory? I am new to the Mac Environment, and other Mac java tips are apreciated. Where do you typlically set the classpath?

thanks a lot mate for the instructions...certainly helpful :D

Many thanks, worked like a charm. Didn't get that classes.jar was in fact rt.jar

Ok it works, thanks! BUT, why it's not like any other install or a simple unpack and configure(maybe)? This needs to be eliminated in future.

There is a slight error in the instructions if you were to cut and paste or follow to the letter the instructions above step two has you create a link through a folder named "classes". The case on the last folder should be capitalized the correct directory is "Classes" so Step 2 would read like this:

2. In order for the installer to see JKD 1.6 on your Mac, you need to create
a sym link for classes.jar:
cd /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home
sudo mkdir jre
cd jre
sudo mkdir lib
cd lib
sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Classes/classes.jar rt.jar

Is this for mac os x server only? Is there any way to install on just plain old mac os x 10.5.8?

Posted by guest on November 17, 2011 at 04:34 AM PST #

guest - JDeveloper will run on a regular mac - no need for X server.

hi, i have a cuestion, does it make my mac slow ???

Posted by guest on November 29, 2011 at 11:02 AM PST #

guest - the answer is no it won't make your mac slow - it would make your
application development faster.

I'm trying to install on an iMac with a SSD and a HDD. The create middleware home does not like spaces in the path. Any recommendations? Both volumes have a name like "Mac HD" and "Mac HD 2". Maybe just change the volume name? I'd like to keep the install as default as possible and am new to Macs, so just wanted to double check...

Hi all. I'm trying to install Oracle 10 or 11g on a Mac OS X 10.5.8 and it seems impossible. I have found a number of forums giving links to this exact download file, but I always end up back at the Oracle website with the message that the file is no longer available. Is there a patch that can get me to a usable version? Am I out of luck? Thanks.
