IE Object Tag: Dynamic Version Support
======================================
<object codetype="application/java"
  width="400" height="50" align="baseline"
  classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
  codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_4_0-win32.cab">
Mozilla's object tag support is not the same as IE's.
<param name="code" value="pak/HelloSwingApplet9.class">
<param name="codebase" value="example_swing">
<param name="archive" value="helpers3.jar,applets3.jar">
<param name="type" value="application/x-java-applet;jpi-version=1.4">
</object>

==> vague
http://java.sun.com/j2se/1.4/docs/guide/plugin/developer_guide/using_tags.html
says that type should be either
  application/x-java-applet
or
  application/x-java-applet;jpi-version=1.4
If the choice for "type" makes a difference, then that should be
documented. If the "type" is actually ignored, then the document
should say so.

The documentation at
  http://java.sun.com/products/plugin/versions.html
says that in theory Netscape 6 should support this tag format. Netscape 6.2.2
and JDK 1.4 do support this tag format.

IE Object Tag: Static Version Support
=====================================
<object codetype="application/java"
  width="400" height="50" align="baseline"

</object>

http://java.sun.com/j2se/1.4/docs/guide/plugin/developer_guide/using_tags.html

  application/x-java-applet
or

documented. If the "type" is actually ignored, then the document
should say so.


Netscape Embed Tag: Dynamic Version Support
===========================================
<embed type="application/x-java-applet;version=1.4"
  width="400" height="50" align="baseline"
  pluginspage="http://java.sun.com/products/plugin/autodl/jinstall-1_4_0-win32.cab"
  code="pak/HelloSwingApplet9.class"
  codebase="example_swing"
  archive="helpers3.jar,applets3.jar">
<noembed>
No java 1.4.
</noembed>
</embed>

==> vague and contradictory
http://java.sun.com/j2se/1.4/docs/guide/plugin/developer_guide/using_tags.html
says that type should be one of
  application/x-java-applet
or
  application/x-java-applet;jpi-version=1.4
http://java.sun.com/products/plugin/versions.html says that
the type attribute should take the value
  application/x-java-applet;version=1.4
for dynamic version support. Which is it?

Netscape Embed Tag: Static Version Support
==========================================

Bug 4689072 says that Netscape support for the IE object tags is going to be
withdrawn. The web page at http://java.sun.com/products/plugin/versions.html
should be changed to remove references to this support.

Just to add one more item...there is another version of the OBJECT tag that
Netscape 6 and Mozilla browsers support that does work. The old APPLET tag
   <APPLET
      width="400" height="50" align="baseline"
      code="pak1/pak2/MyApplet.class" archive="helpers.jar,applets.jar"
      codebase="codebasedir">
   Applets not supported.
   </APPLET>
is equivalent, in this scheme, to
   <OBJECT codetype="application/java"
      classid="java:pak1/pak2/MyApplet.class"
      width="400" height="50" align="baseline"
      code="MyApplet.class" archive="helpers.jar,applets.jar"
      codebase="codebasedir">
    Object tag for applets with 'classid="java:..."' not supported.
    </OBJECT>
