The OBJECT element

To embed Applets in HTML pages the tags <OBJECT> and </OBJECT> are used.

In general, none of the attributes for OBJECT are required. For use as a container for an applet, however, either classid or data is required; width, height, and either codetype or type is recommended. OBJECT is an all-purpose element for generic object inclusion. Applets are just one kind of object that can be included with it.

Attributes

The attributes associated with the embedded object are as follows:

declare

  When present, this boolean attribute makes the current OBJECT definition a declaration only.

classid = URL

  This attribute may be used to specify the location of the object’s implementation via a URL, i.e., the location of the applet.

codebase = URL

  This attribute specifies the base path used to resolve relative URLs specified by the classid, data, and archive attributes. When absent, its default value is the base URL of the current document.

data = URL

  This attribute may be used to specify the location of the object’s data, e.g., a serialized representation of the applet.

type = content-type

  This attribute specifies the content type for the data specified by data. This attribute is optional but recommended when data is specified since it allows the browser to avoid loading
information for unsupported content types.

codetype = content-type

  This attribute specifies the content type of the object specified by classid. For Java applets, this should be "application/java". This attribute is optional but recommended when classid is specified since it allows the browser to avoid loading information for unsupported content types. When absent, it defaults to the value of the type attribute.

archive = URL-list

  This attribute may be used to specify a space-separated list of URLs for archives containing resources relevant to the object. Preloading archives will generally result in reduced load times for objects. Archives specified as relative URLs should be interpreted relative to the codebase attribute.

standby = text

  This attribute specifies a message that the browser may render while loading the object’s implementation and data.

height = length

  This attribute is used to tell browsers to override the natural object height in favour of this value.

width = length

  This attribute is used to tell browsers to override the natural object width in favour of this value.

usemap = URL

  This attribute associates an image map with the object. This is not generally of use when the object is an applet.

name = name

  This attribute assigns the object name.

tabindex = number

  This attribute specifies the position of the current object in the tabbing order for the current document. This value must be a number between 0 and 32767. Browsers should ignore leading zeros.

Example

In practice, the following HTML code would suffice for a standard embedded JAVA applet:

<OBJECT codetype="application/java"
classid="java:HelloWorldApplet.class"
width="200"
height="40">
Java applet that prints a message.
</OBJECT>

An Example of the code for a very basic JAVA Applet is shown here:

import java.awt.*;
import java.applet.*;
public class HelloWorldApplet extends Applet {
public void paint(Graphics g) {
g.drawString("Hello World!", 20, 20);
}
}
