What version of Java does Safari use for running Applets?
Safari uses the most current version of Java delivered with Mac OS X. Updates to Java are periodically available via software update or for download from the Java technology page. Review the Identifying Java on Mac OS X Technical Note to learn how to identify the particular version of Java running your applet. Use the Java Plugin Settings application ( Applications/Utilities/Java/ ) to display the Java Console while running applets in Safari and to select Safari’s default JVM.
