JAVA 1.5 FOR MAC OS HOW TO
JAVA 1.5 FOR MAC OS UPDATE

In other words, updating the Operating System’s links to the old copy of Java is a questionable practice, as it forces every Java application on the system to use the old Java version. Nobody can or should should be changing symlinks in /System/Library/ Frameworks/amework except for Apple software updates (and we are loath to do so, because it inevitably breaks someone) I don’t have anything to add (yet) to what has already been written about installing an old version of Java, however, according to this post from Mike Swingler, Java Runtime Engineer at Apple:

Telling applications that require the older version where to find it, while letting everything else benefit from the latest version.

JAVA 1.5 FOR MAC OS UPDATE

Installing an old version of Java, and keeping Software Update from removing it.

UPDATE: as a side note, for those developing with several JDKs on OS X, have a look at this handy little utility to switch JDK from the command line: setjdk.

JAVA 1.5 FOR MAC OS HOW TO

Have a look at on how to get and install 1.4 and 1.5 JDKs on Snow Leopard.Īlso bear in mind that whenever you run Software Update and a JDK update is installed, you will need to “fix” the symlinks to the 1.4 and 1.5 JDKs. If you are using javac directly, you could try the -source 1.5 and/or -target 1.5 javac options, which may be sufficient for what you’re doing? The 1.6 JDK should be able to produce 1.5-compliant code. If you’re writing code in Eclipse or potentially some other IDE, you should be able to configure it to target 1.5 compliance. Or do I need to try and find an old version of OS X before I can do this work? How to solve this problem? Solution no.

Is there a way to get an actual 1.5 JDK installed on this OS version? It sounds like from that Java is part of the OS update…I’m on Mac OS X v10.6.3 (Snow Leopard). Lrwxr-xr-x 1 root wheel 3 Apr 26 11:53 CurrentJDK -> 1.6 Lrwxr-xr-x 1 root wheel 1 Apr 26 11:53 Current -> A Lrwxr-xr-x 1 root wheel 10 Apr 26 11:53 1.5 -> CurrentJDK Lrwxr-xr-x 1 root wheel 10 Apr 26 11:53 1.4 -> CurrentJDK System/Library/Frameworks/amework/Versions $ ls -l Unfortunately, it looks like OS X doesn’t actually have a 1.5 JDK installed it just links to 1.6:

I’ve got to write some code for a legacy application that is still running JDK 1.5.
