Applet will not load in browser Unsupported major.minor version 48.0

Question

I found this page, and many others like it from search the net:
http://forum.java.sun.com/thread.jspa?forumID=421&threadID=345619
When I first got java installed 1.4.2_02, and that is the directory I always work in.
I HAVE installed:
jre 1.5.0
and
JMF2.1.1e
HOWEVER!!! When i go to the Java icon in the toolbar and dub-click it states:
Java(TM) Plug-in: Version 1.3.1_13
Using JRE version 1.3.1_13 Java HotSpot(TM) Client VM
User home directory = C:\Documents and Settings\javasojava
Proxy Configuration: no proxyAdditionally, if I go to windows Control panel it states:
Java Plug-in 1.3.1_13
My very simple applet program does compile with appletviewer, but
throws this error in browser.
Needless to say, this is extremely frustrating.
Have no other problems building java apps or anything classpath related that am aware of.
Here it is:
CLASSPATH=.;C:\PROGRA~1\JMF21~1.1E\lib\sound.jar;C:\PROGRA~1\JMF21~1.1E\lib\jmf.jar;C:\PROGRA~1\JMF21~1.1E\lib;.;.;C:\j2sdk1.4.2_04\jre\lib\ext\sound.jar;C:\j2sdk1.4.2\2
Thank you!

here is what I get when I open the page you mentioned:

     at java/lang/Thread.run (Thread.java)Why.. because I refuse sun to run <applet tag applets. As with the msjvm the <applet
tag is history so I don't understand why SUN would use depreceated html code in
their 1.5 examples.
Check what I said about versioning and use the object tag and try to run the following
applet:
