JDK 1.5 on MAC OS X

You could install Java 5.0 (1.5) SE 2 and then use the Java Preferences application to select it as your preference.

Here's the link:
http://www.apple.com/support/downloads/java2se50release1.html

If you're adventuresome there's a beta update preview also, but beware and read the notes:
http://adcdownload.apple.com/Java/j2se5.0_release_3_developer_preview2/j2se50release3dp2.dmg

same here - despite having installed j2se 5.0 rel 1 my java -version returns 1.4.2_09

I can see the following:
dhcp-104:/System/Library/Frameworks/JavaVM.framework/Versions
$ ls -ls

Using the supplied Java 5.0 Pref appl does not change this.

I am running 10.4.2 on my G4 Powerbook and noticed that 1.4.2 was the only Java listed. When I went to follow these commands and double clicked on the java preferences I got a window saying:

Could not launch the application because it requires a version of Java that is not installed.

This application requires Java 1.5, but only the following Java versions are installed: 1.4.2, 1.3, 1.3.1, 1.4. Updating to a newer version of Mac OS X may resolve this.

How should I proceed????

Thanks so much for the link. I added 1.5 but upon trying the earlier links instructions to activate it I could no longer get the Terminal to acknowledge which version of java it was running as well as the problem of renaming the java files, it would not allow me. Is this a problem? has 1.5 been initiated after all?

I have not been able to get the Java Preferences utility to work. At least not with the path to java 1.5 via the command line in UNIX. Do I need to use the ln command to link java and javac to the new path? I am trying to run a script that runs my java program which is compiled by java 1.5.

Thanks, greg

Hi, I hope you see this reply. I am desperately trying to figure out how to install Eclipse on the mac. I have downloaded the file from the Eclipse site, unpacked it, and every clue I read indicates the actual Eclipse app file will be in the top level Eclipse directory....except the only thing in that directory is the plugins folder.

How do I actually install Eclipse?

In Terminal use the command:
java -version

to check your installed version.

Never mind.....saw the url earlier in the thread (editing .profile to find 1.5 before 1.4)

However now my Java Web Start doesn't seem to launch apps...
