Java/Eclipse on MacOSX: where is the src.zip?

Question

With the latest Java update on MacOSX 10.6, Eclipse does not find the Java sources anymore.

I am not exactly sure (i.e. don't remember anymore) if I have downloaded the sources manually in the past and put them somewhere or if MacOSX provided them and Eclipse found them automatically.

Does MacOSX have the sources somewhere? (Please no assumptions here. I really want to know that.)

If not, where can I get them?

As I understand it, as of "Java for Mac OS X 10.6 Update 3", there are 3 places you will find Java installed on MacOS.

• /System/Library/Frameworks/JavaVM.framework/ was the old place.
• /System/Library/Java/JavaVirtualMachines/ is the new standard place - there you will find the new release.
• /Library/Java/JavaVirtualMachines is for '...developer previews, and 3rd party JVMs'

Note the MacOS rule of putting Apple-supplied standard components in /System/Library and local extensions into /Library

The JDK installed by default does not now have a src.jar (although it is a JDK, so has javac etc). But if you install the 'Java Developer package' from Apple, you will get

/Library/Java/JavaVirtualMachines/1.6.0_22-b04-307.jdk

which has src.jar under Contents/Home

So I think that the sane thing to do is install the developer package and point to it from your IDE.

Update - for "Java for Mac OS X 10.7 Update 1", having installed the developer package the source can be found at

/Library/Java/JavaVirtualMachines/1.6.0_29-b11-402.jdk/Contents/Home/src.jar
