Need help enabling Java in Opera 11.01

I'm running Windows 98se with KernelEx API enhancement, and I have Java JRE 6 update 24 installed on my system. I'm typing this message using Opera 11.01 / build 1190 (Opera thinks I'm running Windows 2k).

Under Tools->Quick Preferences-> Enable Plugins is checked.
Under Tools -> Advanced -> Plugins, I don't see anything specifically saying "Java runtime 6 update 24", but I do see this:

============
Java Deployment Toolkit 6.0.270.7 - 6.0.270.7
Description: NPRuntime Script Plug-in Library for Java(TM) Deploy
C:\Program Files\Mozilla Firefox\plugins\npdeployJava1.dll
============

And the above item is enabled, and the file npdeployJava1.dll does exist as indicated.

When I go to these web sites:
http://www.java.com/en/download/testjava.jsp
http://javatester.org/version.html

I get:
"Something is wrong. Java is not working" and "Browser has java disabled"

When I go to the Java app in the control panel, under the Advanced tab, Default Java for browsers, I have a check in the "Mozilla family" box, and no check in the "Microsoft Internet Explorer" box. Opera is not listed here (should it be?).

I also have Firefox 2.0.0.20 and java functions correctly as expected when viewing the above web-pages.

In the Java control panel, I DO NOT have "Enable next-generation Java Plug-in" enabled (this option does not work under win-98). Does this need to be enabled for Opera 11?

So basically, what do I need to do, what files should I copy or move around, registry settings, etc, to get Java working properly in Opera 11.01?

Is this such a big thing that nobody knows what to do with it - hence the non-reaction from Opera or others. I have had the same problems since the last Java update (6.29) running Opera 11.52 in portable mode. So, anyone??
