HTML APPLET tags

    <APPLET
        CODEBASE = codebaseURL
        ARCHIVE = archiveList
        CODE = appletFile ...or...  OBJECT = serializedApplet
        ALT = alternateText
        NAME = appletInstanceName
        WIDTH = pixels  HEIGHT = pixels
        ALIGN = alignment

    </APPLET>

If the page is viewed by a browser that doesn't understand applet tags, then the browser will ignore the APPLET and PARAM tags and only display the HTML between the and tags (the alternate HTML).

CODEBASE, ARCHIVE and so on are the attributes of the applet tag; they give the browser information about the applet. The only mandatory attributes are CODE, WIDTH, and HEIGHT.

Applet attributes
CODEBASE = codebaseURL This optional attribute specifies the base URL of the applet--the directory that contains the applet's code. If this attribute is not specified, then the document's URL is used. That is, the browser looks in the same directory from which the webpage was loaded.
ARCHIVE = archiveList This optional attribute describes one or more archives containing classes and other resources that will be "preloaded". The classes are loaded using an instance of an AppletClassLoader with the given CODEBASE. The archives in archiveList are separated by ",".
CODE = appletFile This REQUIRED attribute gives the name of the file that contains the applet's compiled Applet subclass. This file is relative to the base URL of the applet. It cannot be absolute. Either the CODE or OBJECT attribute must be present. The value appletFile can be of the form classname.class or of the form packagename.classname.class.
OBJECT = serializedApplet This attribute gives the name of the file that contains a serialized representation of an Applet. The Applet will be deserialized. The init() method will *not* be invoked; but its start() method will. Attributes valid when the original object was serialized are *not* restored. Any attributes passed to this APPLET instance will be available to the Applet; we advocate very strong restraint in using this feature. An applet should be stopped before it is serialized. Either the CODE or OBJECT attribute must be present.
ALT = alternateText This optional attribute specifies any text that should be displayed if the browser understands the APPLET tag but can't run Java applets.
NAME = appletInstanceName This optional attribute specifies a name for the applet instance, which makes it possible for applets on the same page to find (and communicate with) each other. This attribute will not work with all web browsers.
WIDTH = pixels These REQUIRED attributes give the initial width and height (in pixels) of the applet display area, not counting any windows or dialogs that the applet brings up.
HEIGHT = pixels
ALIGN = alignment This optional attribute specifies the alignment of the applet. The possible values of this attribute are the same as those for the IMG tag: left, right, top, texttop, middle, absmiddle, baseline, bottom, absbottom.
VSPACE = pixels The optional attributes VSPACE and HSPACE specify the number of pixels above and below the applet (VSPACE) and on each side of the applet (HSPACE). They're treated the same way as the IMG tag's VSPACE and HSPACE attributes.
HSPACE = pixels
<PARAM NAME = appletAttribute1 VALUE = value>
<PARAM NAME = appletAttribute2 VALUE = value> . . . 		The PARAM tag is the only way to specify an applet-specific attribute. Applets access their attributes with the getParameter() method.
