Thanks for your help once again. Have just been googling the manifest option and impacts on classpath and becoming slightly confused. Could you send me a link to the paragraph you mention please? Just so you know what I am doing in case I am making other mistakes.

I have a jar created in eclipse on a PC. The manifest file simply says: Manifest-Version: 1.0 Main-Class: main.MyDriver SplashScreen-Image: images/splash.jpg This works fine on a PC, and simply needs to run on a Mac.

Other Java (non Java3D) programs I have run fine on a mac by simply double clicking the relevant jar file. However this doesnt work in Java3D on a Mac. All I want to do is to get my Jar to run on my friends Mac - ideally via a double click. Will this be possible with the current Java3D / Mac OS systems?

When you say 'update the classpath attribute of the manifest' could you give me a tip please. And surely if I affected the classpath via the manifest file this would have an impact on the jar files portability? Dont worry, your blog instructions are the clearest information I have found and are much appreciated. There is a lot of conflicting advice out there, due to the various versions that have been run of Java3D over the years. As said, I have been through the Mac and cleared all the dirty installs I have put in, to the best of my knowledge. I have been using Java3D for nearly 10 years and so unfortunately the old ways of installing the various old versions have become common, and were the first things I tried due to habit with PC's. They also work fine on a PC, and I am not a normal Mac user, and having spent far too much of my time on this problem already am unlikely to become one:-).

Def: Executable JAR is a jar you can run using 'java -jar myexectuable.jar' When you use '-jar' the '-cp' argument is ignored: So how to handle all the other JAR-files your project needs? There are two 'clean' ways: 1) Package your application as a ZIP-file, include your executable jar. Then include all the other JAR-files in for example a 'lib' directory. Then you set up the MANIFEST.MF file in your executable JAR to point to the lib-directory. See documentation on MANIFEST.MF for details. 2) Make a 'fat'-jar.

That means you unpack _all_ jar-files into a single directory and then JAR that directory together. Every class-file ends up in a single JAR-file.

Choose 'Mac OS X (Cocoa)”. For beginners, select the 2nd (or 3rd) entry 'Eclipse IDE for Java Developers”. You will then receive a DMG file (e.g., 'eclipse-java-oxygen-2-macosx-cocoa x86_64.dmg').

This sounds good but it is not without problems. There have been many discussions on these forums about this. There is an 'unclean' way. Install the dependencies in a boot classpath or 'ext' directory in the JVM. I've heard that jogl has been included in Apple JVM this way. Also, this was a a recommended way to install Java3D a long time ago.

This has many, many, many problems with conflicting versions et c since the JVM will favour these classes regardless of what an application packages. This should be avoided at all cost.
