I tried everything. I ask this question on Yahoo! Answers and I got basically what I saw everywhere else: http://answers.yahoo.com/question/i...pnNOlGXsy6IX;_ylv=3?qid=20110807164512AAM4c68 in quotes: answer: I got his Year.java file to work but not the HelloApplet.java and HelloWord.html It says The page Hello-World Applet attempted to load Java content, but Java is unavailable or not installed. On my mom's iMac the page did appear to laod correctly but all that appeared was a black box. I'm guessing the problem is a uninstalled java something or other but I have no idea what that would be since I have a lot of other java programs that work on my computer just not this kind of thing. I'm using 10.5 and the highest version java available for my mac is 1.4.3.
