How to run jEdit + LilyPondTool on MacOS X (solution)

[fiëé visuëlle]

Hi there!

I had big problems getting jEdit to run with LilyPondTool.
Here's how I got it running:

My environment:
- MacOS X 10.4
- Java 1.5 (alias 5) installed via SoftwareUpdate
- jEdit 4.3pre3
- LilyPondTool 0.2.9 (needs SideKick 0.4)

Someone here wrote that the problem is the used Java version, LPT  
needs 1.5

[[Where is my Java?]]
hr$ java -version
java version "1.4.2_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232)
Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode)
[[We're using the wrong version, but how is it called?]]
hr$ which java
/usr/bin/java
hr$ ls -al /usr/bin/java
lrwxr-xr-x   1 root  hr  57 17 Sep 02:37 /usr/bin/java -> /System/ 
Library/Frameworks/JavaVM.framework/Commands/java
hr$ ls -al /System/Library/Frameworks/JavaVM.framework/Commands
lrwxr-xr-x   1 root  wheel  28 17 Sep 02:37 /System/Library/ 
Frameworks/JavaVM.framework/Commands -> Versions/CurrentJDK/Commands
hr$ ls -al /System/Library/Frameworks/JavaVM.framework/Versions
total 40
drwxr-xr-x   11 root  wheel  374 14 Jan 02:08 .
drwxr-xr-x   10 root  wheel  340  3 Jan 02:59 ..
lrwxr-xr-x    1 root  wheel    5  3 Jan 02:59 1.3 -> 1.3.1
drwxr-xr-x    8 root  wheel  272 16 Jun  2005 1.3.1
lrwxr-xr-x    1 root  wheel    5 17 Sep 02:37 1.4 -> 1.4.2
drwxr-xr-x    8 root  wheel  272 16 Jun  2005 1.4.2
lrwxr-xr-x    1 root  wheel    5  3 Jan 02:59 1.5 -> 1.5.0
drwxr-xr-x    8 root  wheel  272  3 Jan 02:59 1.5.0
drwxr-xr-x    6 root  wheel  204  4 Jan 00:35 A
lrwxr-xr-x    1 root  wheel    1  3 Jan 02:59 Current -> A
lrwxr-xr-x    1 root  wheel    5 14 Jan 02:08 CurrentJDK -> 1.4.2

That means, 'java' calls /System/Library/Frameworks/JavaVM.framework/ 
Versions/1.4.2/Commands/java

[[Switch to Java 1.5]]
hr$ cd /System/Library/Frameworks/JavaVM.framework/Versions
hr$ sudo rm CurrentJDK
[[key in your password]]
hr$ ln -s 1.5 CurrentJDK

Now, 'java' calls /System/Library/Frameworks/JavaVM.framework/ 
Versions/1.5.0/Commands/java
and jEdit+LPT should work.
(It didn't for me in the first call, but in the second, strange...)
