Source code for Mac OS X Java Updates [duplicate]

Question

Java for Mac OS X 10.6 Update 3 upgraded to java 1.6.0_22. However, they did not include the source code or JavaDoc. Does anyone know if Apple provides the source, and if so, where to find it?

I'd like to attach the source to Eclipse.

Answer 1

I had the same problem today - I installed the Java Developer package from http://connect.apple.com, but couldn't find "src.jar" in /System/Library/Frameworks/JavaVM.framework/... anymore. On my machine, it's now in
/Library/Java/JavaVirtualMachines/1.6.0_22-b04-307.jdk/Contents/Home/src.jar.

Update: For the latest version from March 2011, the jar is now:
/Library/Java/JavaVirtualMachines/1.6.0_24-b07-334.jdk/Contents/Home/src.jar

Once again, you'll have to download the new Java Developer package first.

Answer 2

What I do is as follows:

Download and install the Java Developer Kit (using your developer AppleId), current version 1.6.0_24-b07-334.jdk, and then in a shell, cd to the /System/Library/Frameworks/JavaVM.framework/Home directory.

Put in symbolic links to the jdk source files, src.jar, docs.jar and appledocs.jar, in the jdk you've just downloaded, that is:

sudo ln -s /Library/Java/JavaVirtualMachines/1.6.0_24-b07-334.jdk/Contents/Home/src.jar src.jar

and similarly for the other two jars.

Then, in Eclipse/Preferences, you can create a new Installed JRE by duplicating the existing one (the existing one points to something like /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home) and then select the new Installed JRE and remove the original.

The Eclipse Projects might need updating to point to the 'new' JRE, but the source and javadocs should now be available for the standard java stuff without further ado.

NB Ensure that the version of the jdk matches the version of your system Java for this to work properly.
