Try: $ java -version It should say: java version "1.5.0_06" | Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-112) | Java HotSpot(TM) Client VM (build 1.5.0_06-64, mixed mode, sharing) | If it says: java version "1.4.2_09" | Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232) | Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode) | you're using the old version. Either the wrong version is active (see http://docs.info.apple.com/article.html?artnum=303526) or you should install the J2SE update. For PPC get the J2SE update here: http://www.apple.com/support/downloads/j2se50release4ppc.html For intel here: http://www.apple.com/support/downloads/j2se50release4intel.html[/url] Please post any followups in an Apple forum.
