Reporter, can you check what are the contents of the plugin directory in the Mozilla install? Was Mozilla installed using the tar ball or using the installer?

I'm having the same problem. Build 2001091303 (0.9.4) on Windows 2000. This distribution, I did something a little different. I completely uninstalled 0.9.3 before installing this one. First hit to java.sun.com asked me to download the plugin. Retrieved plugin from Netscape and installed. Says installed ok. Still doesn't work. Checking ...\mozilla.org\Mozilla\Plugins shows that plugin is not installed. I see that on Sun's site, there is a new version of the JRE, 1.3.1 to replace my version 1.3.0 downloaded from Netscape. I try this version. Install completes, files: NPJava11.dll, NPJava12.dll, NPJava131_01.dll, NPJava32.dll added to Plugins directory. Attempt to hit java.sun.com, applet still doesn't work. Java worked fine under Mozilla distribution 0.9.3.

NPOJI*.DLL must be copied to Mozilla's plugin directory.

Browser, not engine --> Plug-ins

: oji

Copying NPOJI600.DLL to the plugins directory fixes the problem, so we have a workaround. Are NPJava11.dll, NPJava12.dll, NPJava131_01.dll and NPJava32.dll needed as well, or is the Sun plugin installer just going overboard? Why wasn't NPOJI600.DLL installed by either the download from Netscape or the new one from Sun?

NPOJI600.dll does not help! I have it in my plugins folder, Mozilla even recognizes the plugin (about:plugins) but still I can't load any applet Using build 2001100303/Win2K JRE 1.3.1_01 The plugins folder contains: NPJava11.dll NPJava12.dll NPJava131.dll NPJava131_01.dll NPJava32.dll NPOJI600.dll npnul32.dll

Tested with Mozilla build 2001100103 it works fine after manually copy all the plugins dll file into Plugins directory. The only thing we now have should be let the installer to copy the plugins dll file instead of doing it manually.

Perhaps a mention of this should go in the version 0.9.4 release notes, so that people can be made aware of the problem and work-around?

Just installed build 2001101803 on WinNT. Copied npjava11.dll, npjava12.dll and npjava32.dll from JRE 1.3.0-C to plugins directory. Note that there is no NPOJI600 here! And it _does_ work! In contrast I still can't run java applets on Win2K with JRE 1.3.1 or 1.3.1_01, with or w/o NPOJI600.dll

WFM Win2K build 2001102119: The final workaround for me was to remove everything, including the profile, mozver.dat, registry.dat and to reinstall and create a new profile. Now it works :-)

Ok, i have the same bug, here are my comments 1/ i have copy the NPOJI600.dll to mozilla plug-ins and it fix that bug 2/ this bug is a dupe of many ! i can't write it dupe, but in mozilla just enter <java plugin> as keywords to see So someone should change its state... Also the issue of that bug is well known... see: <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=75651">75651</a> Summary: Java installer needs to detect plugin install directory

When I installed the Java2 plugin, the operation states that the installation was successful. However, when I try to start Mozilla 0.9.5, I get the message "The program must close to allow a previous installation attempt to complete. Please restart." I have rebooted, halted, killed processes, etc... in the attempt to make it stop saying that. None of this works. In order to even send this message, I had to make Konqueror my default browser. Thanks in advance.

I used Mozilla 0.9.4 on Win2k and Java2-plugins also didn't work. Now I upgraded to 0.9.5+ and also looked the plugins-dir. All Java-dll's are there and Plugin Manager says it's installed. But it isn't possible to see any Java-applets and the Java Console greyed out. :-(

Using Mozilla/5.0 (Windows; U; WinNT4.0; ; rv:0.9.6) Gecko/20011120 the java plugin installation still doesn't work: As mentioned in other comments, the message for successful installation appaers but even after restart of Mozilla the abovementioned "applet xxx notinited" error occurs. An example for such a site is support.ugs.com. Furthermore almost all bugs one find by searching for "java plugin install" in subject and description seems to refer to the same problem despite having different numbers. Perhaps a kind of merge would be useful.

I have done this to 5 machines now and the bug does not appear to be with the Mozilla installation but with the JRE 1.3.1 installation from SUN. The installation wasnt working from the browser so I did the installations from the SUN JRE package. And it still didn't work. The reason appears to be that the SUN JRE installation package (for windows) does not install the NPOJI600.dll file into the Mozilla pluggins directory. Once I copied this into the pluggins directory, everything worked fine. I'd chalk this one up to SUN.

Well -- let me say then that this also doesn't work under Linux for 0.9.7, RedHat 7.2. Re comment #20, yes, and there are no instructions for Linux.

Hey, groovy, I've got something that works for Linux, and boy do I feel silly now. Download J2RE from Sun (I like the RPM) http://java.sun.com/j2se/1.3/jre/download-linux.html Run the resulting binary: # cd /tmp; sh j2re-1_3_1_02-linux-i386-rpm.bin Softlink: # cd /usr/lib/mozilla/plugins # ln -s /usr/java/jre1.3.1_02/plugin/i386/ns600/libjavaplugin_oji.so Restart Mozilla and life is Javanated once more.

re #20 thanks henrik! works for me now, too. build 2001122603 just needed to copy NPOJI600.dll to plugins-dir.
