macOS I need help: Java 6 & OS X 10.5.8 (NetBeans installation)

[Fraaaa]

I want to learn java and I've been suggested by a friend to use NetBeans; however, when I downloaded and ruined the NetBeans 6.9 gave me this message:

Cannot run on older version of Java 6 Standard Edition.
Please install Java 6 Standard Edition or newer or use --jdkhome switch to point to its installation directory.

But then when I go on java.sun.com to download Java SE doesn't give me OS X as platform to download.

Any help?

Oracle does not produce a jvm or JDK for OS X. Apple does. If you have a core 2 duo or newer CPU you can get the Java 6 update for 10.5 from apple software update. Otherwise you have to get 10.6 for java6

Also complicating matters is that, on 10.5, Java 6 is only available as a 64-bit Intel binary. This makes running anything that requires Java 6 that isn't itself 64-bit ready difficult.

EDIT: Due to the fact that NetBeans requires JDK 6 AND is not 64-bit ready, Snow Leopard is required to run it. However, the recently released Eclipse 3.6 (Helios) still runs with Java 5 or 6, AND is 64-bit ready, so it will run on Leopard or Snow Leopard (but not on Tiger or earlier).

I downloaded the update 7 for 10.5, but I guess NetBeans is the problem; it kept gave me that message.

I downloaded Eclipse, is working and I'm fine with it; I just needed any compiler that works.

Thanks guys.

Netbeans runs on both 64bit and 32 bit JVMs and has been since inception since it is a 100% java program, unlike Eclipse. In fact Netbeans is available as a os independent download, something impossible for the Eclipse platform to produce. While the latest release, 6.9, requires Java6, the previous release 6.8 runs on Java5 and Java6.

Eclipse is available as a 64bit or 32bit, you have to choose which one you want to use.

I would encourage you to give Netbeans another chance, I greatly prefer it over Eclipse. It is a true integrated environment unlike Eclipse which is a series of editors and plug-ins.

Ah, I didn't know that about NetBeans. However... there are several things I really do not like about it:

1. No mass source-code format option. Come on, Eclipse has had this for ages. Why the heck can't you format all source files in a package/project at once?
2. No way I've found (yet) to bring up a list of compile errors and warnings in NetBeans 6.9, for all source files in the project/group. What's up with that?
3. No way to specify native file location for libraries. Another feature Eclipse has that I happen to need.

While this discussion is going outside the bounds of the original question, I do want to correct a few things here:

1. Netbeans does not have code formating, but this solution is slated for inclusion in 7.0 (bug 25377). To be honest, its not a feature I need often. Our company has a very specific code style and everyone writes to that standard.
2. All errors and warnings for a project are available in the "Tasks" panel. You can even create your own filters for this panel to see only those items you are interested in.
3. Native library locations can be specified in the "run" ANT target definition for the project.

Re: netbeans 6.9 on os x

try this http://blog.alastairdawson.com/2010/07/15/getting-netbeans-6-9-to-work-on-os-x-10-5-8/

It won't run for me

Doesn’t work for me. I have 1.6.0_20 and netbeans 6.9.1, running latest Snow Leopard (10.6.4). When I try to launch netbeans, it bounces in the dock a few times at launch, then quits without error message, even after updating the conf file as described by Alistair Dawson.

With any luck, error messages will be in the Console Messages window of Console.app.

In Finder, Go > Utilities > Console.app

Also, Alastair Dawson's comments are directed at running on 10.5.8. Trying to apply them on 10.6.4 may not work.

if all else fails, forego the IDE and use the text editor Smultron

compile in the terminal with

javac <filepath>

and run the class file with

java <class name>

How to get rid of Java 5 and install Java 6, pls?

Hello,

I figured that my Leopard has "inherited" Java 5 during the transfer of my files from the old computer or it came preinstalled. Anyway, at present it is 1.5.0_26.
Have read many posts in the forums and decided to go for NetBeans 6.9 with which I need Java 6.
Also came across some mentions that in order to delete/reinstall Java platform the entire OS should be reinstalled. Would that be true? What would be the best way for me to proceed, pls?

Step 1: Identify your machine. Is it PPC or Intel-based? 32-bit or 64-bit?
This information can be obtained by choosing "About This Mac" from the Apple menu and copy/paste the Processor identity from the dialog window into a reply posted here.

Step 2: Run Java Preferences.app (it's located in your Utilities folder, possibly under the Java sub-folder). Choose the General tab if it isn't chosen. Does it list an available Java 6 or not, in the list inside the Java Applications section?

Once you've provided the above information, the next steps can be determined.

Also came across some mentions that in order to delete/reinstall Java platform the entire OS should be reinstalled. Would that be true?

Yes, that's one way. Where did you read these mentions?

Another way is to do a backup before installing a Java update, then you can go back to it without a full reinstall. That's how I usually do it.

You can also change the default. To do that, go to Java Preferences, in your Utilities folder.

Thank you!
I read in many forums by doing google search each time a question arose and this is how I came across this Java uninstallation issue.

I have a strong feeling that your info and the link posted by kreek in addition to all the info in this thread will solve it fully

I just need developper tools installed it seems to point Netbeans to Java 6 according to kreek's link.

Wow! This sorted all with one click!!!
Thank you!!!

I am trying to get netbeans 6.9.1 to install my my Macbook, its only a core duo, running 10.5.8. I suspect that being a core duo is why I can't install it??
