Helping Setting JDK 1.6 in Leopard

[Unnsse Khan]

Hello again,

Need assistance with setting the JDK in OS X Leopard to 1.6.

I did the following steps:

(1) cd /System/Library/Frameworks/JavaVM.framework/Versions/

(2) rm -rf CurrentJDK

(3) ln -s 1.6.0 CurrentJDK

(4) Verified the new CurrentJDK alias by doing the following:

ls -al  /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK
lrwxr-xr-x  1 root  wheel  5 Jul  5 02:16 /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK -> 1.6.0

However, when I check the version of java from the command line, I get this:

java -version
java version "1.5.0_19"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_19-b02-304)
Java HotSpot(TM) Client VM (build 1.5.0_19-137, mixed mode, sharing)

When I checked which java this is what I got:

$ which java
/usr/bin/java
untz@Valkyrie:~ $ ls -al /usr/bin/java
lrwxr-xr-x  1 root  wheel  74 Jun 24 04:55 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

Has anyone set the JVM / JDK in OS X Leopard to 1.6?

Happy programming...

There's an app under Applications/Utilities/Java called JavaPreferences that lets you set what JRE/JDK you want to run as default, as well as various other options.

Nathan, thank you so much!

Excellent... I changed the order in the Java Preferences pane and now it works!

$ java -version
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03-211)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02-83, mixed mode)

Happy programming...

Did you notice an increase in performance? I installed 1.6 this evening. Netbeans is now much faster. Yes!

I didn't have time to check it out to that extent, per se.

NetBeans has evolved very nicely, but I am still an Eclipse guy...
