From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.6) Gecko/20011120
BuildID:    2001112009

it appears that data of the type application/x-java-applet without the version
modifier always requests the plugin download. If the mime-type has a version
then the applet executes correctly.

Reproducible: Always
Steps to Reproduce:
1. Enusre java plugin is loaded
2. go to URL

Actual Results:  "click here to get the plug-in" displayed

Expected Results:  java applet should be executed

With tomcat, JSPS loaded with 

<jsp:plugin type="applet"
            width="475" height="350"
    <jsp:param name="MESSAGE" value="Your Message Here" />

request the plugin.

Adding the jreversion= option means the applet executes as expected.

<jsp:plugin type="applet"
            width="475" height="350"
    <jsp:param name="MESSAGE" value="Your Message Here" />

Internet explorer executes the applet via the plugin even without the version.

omg, it's year 2002 now ! Chris, pls try a recent build ( within this week) and 
try to reproduce this issue.  Also, bugs involving the 'java plugin' go to OJI 
and not 'Plugins'. Thx!

I have had this problem for a very long time.  

I typically download a new build (mozilla-win32-installer-sea.exe) about once
per week.  I have never gotten java to work just after an install.  I generally
always have to copy the NPJava*.dll files into my Plugins directory and that
doesn't see to work either.  It has been quite a long time since Java has worked
for me in Mozilla.

Win98 (4.10.1998)
Mozilla 2002020512
Java j2re-1_3_1_02-win  (I assume that is JRE1.3.1 ?)

Chris, I couldn't reproduce this bug at all.
It loads fine on my windows 98 (commercial build: 2002-02-07-06-trunk)
with jre 1.3.1.

Here is my java console window:

Java(TM) Plug-in: Version 1.3.1
Using JRE version 1.3.1 Java HotSpot(TM) Client VM
User home directory = C:\WINDOWS\Profiles\pmac000

Proxy Configuration: Browser Proxy Configuration

c:   clear console window
f:   finalize objects on finalization queue
g:   garbage collect
h:   display this help message
l:   dump classloader list
m:   print memory usage
q:   hide console
s:   dump system properties
t:   dump thread list
x:   clear classloader cache

Is this problem still reproducible?
Are you able to open java console? 
What about:plugin says?

With version 2002032803 I'm still getting this problem with my win98 machine. 
At work on my win2K machine, it is working fine.

> Are you able to open java console?

Java Console does not open.

> What about:plugin says?

It shows that the following java dlls were loaded with their mime types:

application/x-java-applet;version=1.1.1 Java Applet Yes
application/x-java-bean;version=1.1.1 JavaBeans Yes
application/x-java-applet;version=1.1 Java Applet Yes
application/x-java-bean;version=1.1 JavaBeans Yes
application/x-java-applet Java Applet Yes
application/x-java-bean JavaBeans Yes

application/x-java-applet;version=1.2 Java Applet Yes
application/x-java-bean;version=1.2 JavaBeans Yes
application/x-java-applet;version=1.1.3 Java Applet Yes
application/x-java-bean;version=1.1.3 JavaBeans Yes
application/x-java-applet;version=1.1.2 Java Applet Yes
application/x-java-bean;version=1.1.2 JavaBeans Yes

C:\PROGRAM FILES\MOZILLA.ORG\MOZILLA-03-28\plugins\NPJava131_02.dll
application/x-java-applet;jpi-version=1.3.1_02 Java Applet Yes
application/x-java-bean;jpi-version=1.3.1_02 JavaBeans Yes

application/x-java-applet;version=1.3 Java Applet Yes
application/x-java-bean;version=1.3 JavaBeans Yes
application/x-java-applet;version=1.2.2 Java Applet Yes
application/x-java-bean;version=1.2.2 JavaBeans Yes
application/x-java-applet;version=1.2.1 Java Applet Yes
application/x-java-bean;version=1.2.1 JavaBeans Yes

When I goto, on the right, third box down, I get the "Click
here to get the plugin".  I haven't tried the "click here..." for a while so
I'll do it just after submitting this comment.  If it works, I'll make another

There is a missing DLL : Npoji600.dll (Jre1.3.x) or npoji610.dll (Jre1.4)
Can you copy that dll from the jre installation into mozilla plugin folder ?

Yes, adding Npoji600.dll fixed the problem.  The java applet on now runs correctly.  Thanks for the suggestion.

PS: When I clicked on "get the plugin" it started the download, installed java
and then crashed when I tried to go to  Here is the Incident ID:
TB4803002X which describes the problem a bit more.

Also, I still cannot get GameCast to run from:  It starts up but never finishes.

So, original problem is resolved. 
I suggest to file separate bug on new problem and resolve this one
(to keep track of solutions). 

It still interesting why plugin installation does not always copy 
required lib but i belive there is a separate bug about plugin installation
on windows platform.
