Works on Mac OS X 10.4.11 (Intel Core 2 Duo).

After installation, you must go to Applications > Utilities > Java > Java SE 6 > Java Preferences. In the top drop-down box select Use Version: “Java SE 6″. Then in the middle of the same page, under “Java Application Runtime Settings” drag “Java SE 6″ to the top of the list. Click save in the bottom right corner. To test, open terminal and type java -version. Should now show:

java version “1.6.0-dp”
Java(TM) SE Runtime Environment (build 1.6.0-dp-b88-34)
Java HotSpot(TM) Client VM (build 1.6.0-b88-17-release, mixed mode, sharing)

NetBeans sure looks pretty compared to soylatte “hack” =)

I’ve visited the URL you recommended. I think i’m not getting the applet i should on that page. On the top of the page says:

How do I test whether Java is working on my computer?
This article applies to:

If your applet is not displaying properly, please check these additional configurations.

1. Enable Java through your Web browser
2. Enable Java through the “Java Plug-in Control Panel”
3. Clearing your Web Browser Cache

If you are unable to perform any of the steps above due to an error, please reinstall Java. Download and installation instructions

I’ve cleared my cache and all, but don’t understand how to test java on my mac.

My question is: when i open the java preferences window, shouldn’t i see J2SE 1.6.0 as an option?
I have only 2 options: J2SE 1.4.2 and J2SE 5.0 – i’ve selectec 5.0

But on the little case further down the window i have also 1.6.0 – which i can drag to the top of the list.
Should i delete any temporary files. I really don’t want to mess this up.

So what’s the problem you are facing? Did you test java by visiting the URL I mentioned above?

This is what i get:
java version “1.6.0-dp”
Java(TM) SE Runtime Environment (build 1.6.0-dp-b88-34)
Java HotSpot(TM) Client VM (build 1.6.0-b88-17-release, mixed mode, sharing)

What i described before is what i see in the preferences window of java.

Hi Pietro

I am not sure I understand where you’re stuck. What do you see when you type “java -version” in Terminal? You can even test your Java installation by visiting this page:

I’ve tried the whole process and it happened as you described, but…
When i open java preferences, i manage to set version 1.6.0 on top of java application runtime settings, but above on the same window i only have option for J2SE 1.4.2 and 1.5 – shouldn’t there be 1.6 there as well?
I still don’t have this right

Help, please…
Thank you so much so far!

You can definitely give it a shot and as long as you backup the files mentioned in Step 3, you have nothing to lose. At worst, it won’t work – can’t mess with your system.

Do let us know how it goes!
