Java5 on Snow Leopard

Question

Hi,

I need Java5 (not 6), but Snow Leopard comes with only Java6. There is /System/Library/Frameworks/JavaVM.framework/Versions/1.5, but that just points to 1.6.0:

 $ ls -la /System/Library/Frameworks/JavaVM.framework/Versions/
 lrwxr-xr-x   1 root  wheel    5 Sep 24 20:12 1.3 -> 1.3.1
 drwxr-xr-x   3 root  wheel  102 Jul 21 07:35 1.3.1
 lrwxr-xr-x   1 root  wheel   10 Sep 24 20:12 1.5 -> CurrentJDK
 lrwxr-xr-x   1 root  wheel   10 Sep 24 20:12 1.5.0 -> CurrentJDK
 lrwxr-xr-x   1 root  wheel    5 Sep 24 20:12 1.6 -> 1.6.0
 drwxr-xr-x   7 root  wheel  238 Sep 24 20:12 1.6.0
 drwxr-xr-x   8 root  wheel  272 Sep 24 20:12 A
 lrwxr-xr-x   1 root  wheel    1 Sep 24 20:12 Current -> A
 lrwxr-xr-x   1 root  wheel    3 Sep 24 20:12 CurrentJDK -> 1.6

Can I install the real 1.5 from somewhere?

Answer 1

Hmm, i do not have installed 10.6 yet (it is on the way), but the versions directory looks strange. Where is 1.4? And no version should point to CurrentJDK! My 10.5 installation is the following:

r2d2:~ arne$ ls -l /System/Library/Frameworks/JavaVM.framework/Versions 
total 56
lrwxr-xr-x  1 root  wheel    5 16 Sep 19:14 1.3 -> 1.3.1
drwxr-xr-x  3 root  wheel  102 14 Jan  2008 1.3.1
lrwxr-xr-x  1 root  wheel    5 16 Sep 19:14 1.4 -> 1.4.2
lrwxr-xr-x  1 root  wheel    3 21 Feb  2008 1.4.1 -> 1.4
drwxr-xr-x  8 root  wheel  272 21 Feb  2008 1.4.2
lrwxr-xr-x  1 root  wheel    5 16 Sep 19:14 1.5 -> 1.5.0
drwxr-xr-x  8 root  wheel  272 21 Feb  2008 1.5.0
lrwxr-xr-x  1 root  wheel    5 16 Sep 19:14 1.6 -> 1.6.0
drwxr-xr-x  8 root  wheel  272 26 Sep  2008 1.6.0
drwxr-xr-x  8 root  wheel  272 16 Sep 19:14 A
lrwxr-xr-x  1 root  wheel    1 16 Sep 19:14 Current -> A
lrwxr-xr-x  1 root  wheel    3 16 Sep 19:14 CurrentJDK -> 1.5
r2d2:~ arne$

Do other 10.6 users have the same problem? I am not shure about installing the Java 5 package for 10.5 will work on 10.6. Someone have experience?
