Click to expand.Right, but the OP wanted to install Java 1.5.0, a release Apple has only qualified and shipped on 10.4, on 10.3.9. I was suggesting that this was not likely to work flawlessly, and in fact likely to fail spectacularly. If the OP limits himself to those areas where Apple has not used an 10.4 features in their 1.5.0 implementation, then he may get something useful done with it, but those areas are rather limited - nothing GUI is my understanding. As always, since I have not tried it myself, this is somewhat conjectural, but based on various responses on java-dev, which indicated that forcing an install on 10.3.9 was not a way to increase your happiness.

Click to expand.It could be a good debate but I don't have time for it and I am not a java developer/business etc. Giving whatever java latest is to LATEST OS users and leaving the others in cold is something so awful that I can't even comment about it. Its not even Apple to blame, the lazy guys at Sun are to blame too. And people wonder why developers, especially end user product coders still stay away from java. As I said, its not my job, I only care if Thinkfree office works or not and (knocks on wood) it works here.

Click to expand.I am a biotech consulting, primarily focussed on Java and databases. When a client has a problem, I suggest that they weigh the costs of paying me, buying software that solves the problem, or hiring in-house. Given that OS X costs roughly the same as an hour of my time, upgrading can make a lot of sense.

On the other hand, if you are cash strapped, time may be easier to get at than money. As I said above, though, it sure looks like you are going to spend a lot of time, and not for a lot of benefit.

OK.I'm hardly a programmer, but I have to take a JAVA class as part of my Masters Degree and I'm having issues getting 1.5.0 to be recognized in Eclipse. If anyone has experience with this, could you please help.

I have set 1.5.0 as the Default, but Eclipse is not seeing it under its preferences. When I search for it under the Installed JREs menu I get: 'No JREs found in /System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home' This is the similar directory that is used for the older JREs, so I don't know what to do. 5.0 is set as the default everywhere else, just not in Eclipse. This means much of my code will not compile making it a little cumbersome to test out my programs. I'm relatively new to Macs and I'm not a programmer to begin with so this is about as easy for me as deciphering hieroglyphics.

Java 1.5 For Mac

Anyone that has a clue, please help! Thanks Jesse.

First I assume it does not work from the command line in Terminal either. Open terminal and run java - version If you do not see this: $ java -version java version '1.5.002' Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.002-56) Java HotSpot(TM) Client VM (build 1.5.002-36, mixed mode, sharing) Then java 5 is not set up properly on your machine. To do that, in terminal type the following commands: $ cd /System/Library/Frameworks/JavaVM.framework/Versions $ sudo mv Current Current.old $ sudo ln -s 1.5 Current (taken from ) Now see if Eclipse will pick up the new Java VM.

Click to expand.Alternatively, assuming Java 1.5 is installed correctly on the machine (test using 'java -version' on the command line as mentioned above) you can simply set up eclipse to use the 1.5 JVM directly rather than messing with changing the current system JVM folders. To set Eclipse to use the 1.5 JVM, open Eclipse (for Java 1.5 you should be using Eclipse 3.1 or greater), then select the Window-Preferences.' In the preferences dialog navigate to 'Java-Installed JREs'. Check that the 1.5 JVM is listed.

Java 1.5 Mac Os

If it is not listed, click on the 'Add' button. Set the 'JRE type' as 'MacOS X VM', 'JRE Name' as 'JVM 1.5.0' 'JRE home directory' as '/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home', 'Default VM arguments' as ', and select 'Use default system libraries'. After you have added the 1.5 JVM, select it as the default JVM in the 'Installed JREs preference dialog. Now you should be all set. You may need to recreate your projects for the updated setting to be used in the projects.
