<APPLET> tag.
Instead you are supposed to use the <OBJECT> tag.
For the purposes of ewbedding applets,
the <OBJECT> tag is used almost exactly like the
<APPLET> tag except that the
class attribute becomes
the classid attribute. For example,
<OBJECT classid="MyApplet.class"
CODEBASE="http://www.foo.bar.com/classes" width=200 height=200
ALIGN=RIGHT HSPACE=5 VSPACE=10>
</OBJECT>
<OBJECT> tag is also used to embed ActiveX controls
and other kinds of active content, and it has a few additional
attributes to allow it to do that. However, for the purposes
of Java you don't need to know about these.
The <OBJECT> tag is supported by Netscape ???? and later and
Internet Explorer ???? and later. It is not supported by earlier versions
of those browsers so <APPLET> is unlikely to
disappear anytime soon.
You can support both by placing an <APPLET>
element inside
an <OBJECT> element like this:
<OBJECT classid="MyApplet.class" width=200 height=200>
<APPLET code="MyApplet.class" width=200 height=200>
</APPLET>
</OBJECT>
<OBJECT> will
ignore its content while browsers that don't will display its content.
PARAM elements are the same for <OBJECT>
as for <APPLET>.
For the complete story, you can read about the <OBJECT> tag
in the HTML 4.0 specification.
