12.3 Including Applets for the Java Plug In
275
The 
jsp:plugin
 element instructs the server to build a tag appropriate for
applets that use the plug in. Servers are permitted some leeway in exactly how
they implement this support, but most simply include both 
OBJECT
 and 
EMBED
.
The jsp:plugin Element
The simplest way to use 
jsp:plugin
 is to supply four attributes: 
type
, 
code
,
width
, and 
height
. You supply a value of 
applet
 for the 
type
 attribute and
use the other three attributes in exactly the same way as with the 
APPLET
 ele 
ment, with two exceptions: the attribute names are case sensitive, and single
or double quotes are always required around the attribute values. So, for
example, you could replace

        WIDTH=475 HEIGHT=350>
with
            code="MyApplet.class"
            width="475" height="350">
The 
jsp:plugin
 element has a number of other optional attributes. Most,
but not all, parallel attributes of the 
APPLET
 element. Here is a full list.
type
For applets, this attribute should have a value of 
applet
. 
However, the Java Plug In also permits you to embed JavaBeans 
elements in Web pages. Use a value of 
bean
 in such a case.
code
This attribute is used identically to the 
CODE
 attribute of 
APPLET
, specifying the top level applet class file that extends 
Applet
 or 
JApplet
. Just remember that the name 
code
 must 
be lower case with 
jsp:plugin
 (since it follows XML syntax), 
whereas with 
APPLET
, case did not matter (since HTML 
attribute names are never case sensitive).
width
This attribute is used identically to the 
WIDTH
 attribute of 
APPLET
, specifying the width in pixels to be reserved for the 
applet. Just remember that you must enclose the value in single 
or double quotes.
