For your error
â€œCommand /Developer/Private/jam failed with exit code 127â€³

Xcode cannot find the path to the Developer directory. Set the right path.

I found the Apple article helpful up to the point where it says double click on the java executable … what java executable? I couldn’t find one, and my application compiled with Java 1.5 but failed with no error when run from the Finder. I was able to cd inside the application with a shell and see error messages. I was also able to start my java code by giving an explicit path to the 1.5 version of Java. I found this hint at Apple — http://developer.apple.com/releasenotes/Java/Java50Release3RN/index.html — that suggested setting the JVMVersion key of the Info.plist in the Application. I was able to make my application work from the Finder after manually editing the plist. Finally, I found on my Target window in Xcode, visited by double clicking the target, under Info.plist entries, Simple View, Pure Java Specific, a dropdown box called “Target VM Version”. I typed in “1.5+” (without the quotes) and then the application worked. Note that I also had to change the target settings, source settings, and JAVA_COMPILER build setting as instructed above.

i installed Java 1.5, and opened Xcode. I have made the proper changes described in this Article, but when i try to compile my Project, it says “Command /Developer/Private/jam failed with exit code 127″ in the “build results” window.

Can anyone help?

AAAhhhh…. FINALLY! IT WORKS! Ok, I’ll admit I’m new to this, and I have been struggling for some time now to get Java 5 to work in Xcode. Thank you Yaw Anokwa for your helpful template. It’s works wonderfully in Xcode 2.2.

J2SE 5 auf Mac OS X

Ach, ich liebe es. Diese ganzen zig Bezeichungen die sich alle irgenwie aehnlich anhoeren, besonders fuer Leute deren Muttersprache nicht grade Englisch ist. Die Ganzen einzelnen Versionen eben dieser Programme. Und daraus folgende Inkompatibilitaeten…

This was a really useful reference, but I ran into a problem where I could compile but could not run the Java 5 code.

It seems that Xcode 2.1 project file mangles the -jar Â«PROJECTNAMEASIDENTIFIERÂ».jar argument in the executable. Fortunately, I was able to tweak the old Xcode file to make it work and I have posted copy of the working template and installation instructions here:
