Command Line Applications

Running java from the command line runs Java 1.4.1. The Java commands in /usr/bin are linked to the most current version of Java tools on the system. In this release they are linked to commands in /System/Library/Frameworks/JavaVM.framework/Versions/1.4.1/Commands. If you need to run the Java 1.3.1 version of a command line Java tool, you may do so by explicitly calling the appropriate Java 1.3.1 command in /System/Library/Frameworks/JavaVM.framework/Versions/1.3.1/Commands.

If you are building shell scripts for distribution to customers that link to a specific version of a Java command in /System/Library/Frameworks/JavaVM.framework you should consider wrapping your application as a Mac OS X application with Jar Bundler. Specifying a specific path in the operating system (other than /usr/bin) is not the most robust solution since changes to Mac OS X may render these paths obsolete and your application broken.
