    Default Can't get applet to work on Safari..

    Ok, so I'm new here and kind of new to the whole Java thing but I'm taking a course at school and we learned how to open a Java applet using HTML and a web browser. Now I'm trying to use the Mac's Web Sharing to allow all the computers on my network to view my applet. So far it has worked perfectly. The only problem arises when I try to open up the applet using Safari. Firefox seems to work but Safari doesn't. If you need to see the HTML, here it is:

    <html>
    <p style="text-align: center;">
    <applet code = "Candle.class" width="350" height="200">
    </applet>
    </p>
    </html>

    All that results is a blank page and what seems to be Safari trying to load the applet but never able to. Can anyone help?? It would be much appreciated.

    Is there an error message in the browser's java console?

    I don't know how to access the java console when the page doesn't even load.

    Is the plugin installed for that browser?

    Yes, java itself works fine. The plug-ins are up to date and everything.

    So does the Java console open on your screen when you load a page with an applet in it? If it doesn't you could try starting the Java ControlPanel (on my Ubuntu PC I open a terminal and enter 'ControlPanel' - in exactly that case), going to the 'Advanced' tab, expanding the 'Java console' element and choosing 'Show console'.

    If the Java test applet is working and your own project is not, perhaps it's not a Java plugin issue though. What happens if you try to load the class file directly by entering its URL in the Safari URL bar? For example the Java test applet can be downloaded in Firefox by combining the page URL:
    with the codebase in the applet tag (see the page source)
    codebase="../../applet"
    and the archive name
    TestVM2-test.jar
    to give the URL of the jar file
    Firefox attempts to download the file, explaining that it's a 'Java archive' - so it must at least have read a response header by the time the dialog is shown.

    Can you verify on your Mac that Safari is downloading the class file? I don't know Mac Web Sharing - is there an equivalent to Apache's access_log which tells you what requests clients have made and what the response codes / content lengths were?

    load: class Candle.class not found.
    The browser is looking for the class: class in the package Candle. It is looking for the file: class.class in the Candle folder. Remove the .class from the code= tag so it looks for the class: Candle
    code= should refer to the class, not the filename

    Are you saying the html should say:

    HTML Code:
    <applet code = "Candle" width="350" height="200">
    </applet>
    The name of the applet is "Candle" btw.

    What happened when you tried it with only the class name (not the filename)?
