Applet no webserver nao funciona!

<!--=================== Java APPLET tag ================================-->
  <!--
    This tag is supported by all Java enabled browsers. CODEBASE specifies
    the base URL of the applet - the directory that contains the applet's
    code. If this attribute is missing the documents base URL is used
    instead. One of CODE or OBJECT must be present. Archive files speed
    loading of applets through a compressed wrapper for applet resources.
    The ALT attribute gives text to display if the browser understands
    the APPLET tag but can't run Java applets. WIDTH, HEIGHT, ALIGN,
    HSPACE and VSPACE are defined in the same way as for IMG elements.
