I haven't forgoten the 'NPOJI610.dll'. It's really a bug.

how about at least listing what you have in about:plugins?
doesn't block development.

Is Windows:Start\Systemcontrol\Java Plug-in\Browser\[]Mozilla 1.1 or higher 

enabled ?
It will not work without this checkbox and the JRE needs Registry keys from the
installer (.zip doesn't work) to find Mozilla.

I am seeing the same problem under linux. From the command line here is the
error that it spits out.
The first one is using my installed jre and the second is with the jre
downloaded by the browser.

about:plugins - lists all my other plugins except java.
LoadPlugin: failed to initialize shared library
undefined symbol: GetGlobalServiceManager__16nsServiceManagerPP17nsIServiceManager]

LoadPlugin: failed to initialize shared library
undefined symbol: __vt_17nsGetServiceByCID] You don't see the same error.
Your problem is a "user doesn't read the release notes" bug

on win2k, You should also install mozilla by using install wizard because it
will write register items. JRE search those items to support browser.

if you install jre1.4.2 on win2k, please enable java plugin for mozilla >=1.1
(on Java Control Panel)

Joshua, can you mention what's needed exactly, the following reg key didn't work
(and yes I enabled Mozilla 1.1 in the Java control panel, which gave me an
error, telling me it couldn't be done):

Does Resolution INVALID mean that it becomes fixed, if not why not?

For those that find this bug, and want to fix this error (because Mozilla
refuses to):

The JRE installation is looking for a registry key that Mozilla no longer
creates. If you manually create it, you can get Java working in Mozilla. The reg
keys needed are:




"Install Directory"="C:\\Program Files\\Mozilla\\bin\\"

You have to edit the "Install Directory" to your installation path. Now run the
Java Control Panel applet and check off Mozilla in the browsers tab.

Dumb question:
How does one access the Mozilla Java Control Panel applet? I know where the Java
console is. Help has no help on Java either.

This also seems like a valid bug to me. Why isn't the installer creating the
correct keys? Or why isn't Sun changing their plugin?

It's actually in the Windows Control Panel as "Java Plug-in"

Comment 23

I changed the registry settings, but used "c:\\Program files\\Mozilla\\" for the
location (there is no bin directory in Windows), and the Java control panel says
Mozilla is not properly installed, so it cannot enable Java for Mozilla.

It has to be the path to the Mozilla.exe file, and it has to include a trailing

check off Mozilla (in java panel) won't work with Firebird (with no previous
Mozilla install), however, the registry hack enables Java working in Firebird:
(and I even tried to create a dummy Mozilla.exe file)

I installed today's Mozilla build, and it removed those registry changes!
But after putting them in again, with the trailing \,the Java control panel
still says Mozilla is not installed properly.

With help from Jerry Baker, I got the java control panel applet to let me
nominate Mozilla for use by the 1.4.2 plugin. His post was slightly wrong.
Apparently, the problem is that Mozilla now adds an (En) after the 1.5b in the
registry tree, and you have to duplicate that branch with 1.5b rather than 1.5b
(En). (His post said to use 1.0).
However, my applet load in
still fails, so I am not sure this is truly a duplicate.

someone mind to clear up this nonsense and reopen this issue ? I like to.
Nothing is solved yet - and the sun-JRE works fine with IE, but not with Mozilla.

The sun JRE works fine with Mozilla on win2k
