Using Red Hat 9, I installed Java 1.4.2_03, the RPM. I followed the directions carefully and completed the process by creating the necessary symbolic link in the Mozilla plugin directory. Everything worked fine.

I decided to upgrade to Mozilla 1.6. Couldn't find any workable RPM's so I installed the binary download from Mozilla. Again, everything went fine. Since the issue of gettting Java to work with Mozilla seemed to just be the matter of the symbolic link, I created that again in the Mozilla plugins directory. Now whenever I try to start Mozilla (usr/local/mozilla/mozilla) I get an error message that says "internal error on browser end: No manager for initializing factory?" Haven't a clue what that means, but Mozilla won't start and I cure the problem by deleting the java link. But of course I can't see anything done in Java on a web page.

And, yes, I did completely uninstall and remove the directories of my former version of Mozilla (1.2, the one that comes with RH 9).

Did you make sure to symbolically link against the libjavaplugin_oji.so that was compiled with gcc-3.2. It's the one in the ns610-gcc32 (or something like that) folder. The one in the ns610 folder was compiled with gcc-2.9 and doesn't work with recent versions of Mozilla.

Well, if I had any clue I needed to do that, I would have! You were right, though. I made this change and it seems to be working fine now. I went back to the instructions on Sun's site (which are not all that easy to find), looking to see if I missed this clue somewhere. The closest they come is where they say, "For the SuSE 8.1 or higher Mozilla browser, replace ns610 with ns610-gcc32 in the ln command above". Since I'm using Red Hat, I never paid much attention to the sentence. Thanks for the clue.

I tried the symbolic link and I still can't get the plugins to work with mozilla 1.7a
I got the java 1.4.2-03, what do i need to do I am getting frustrated

Your problem may just be Mozilla 1.7a. This isn't even in beta stage yet, so there are likely to be problems with it.

That was the problem so I got rid of mozilla 1.7a and put 1.6 in and no problems. I will be back with more problems I bet

I'm trying to upgrade from about version 1.2 to 1.7. I've created symlinks to the n610-gcc32 java library in every mozilla and netscape plugin directory I can find ({/usr/lib,/usr/local}/{mozilla,netscape}/plugins/, and ~/.{mozilla,netscape}/plugins).

I still get the bleeping "factory not found" error. I can run /usr/bin/mozilla.orig (the old binary) without a problem (other than the normal 1.2 bugs), but I can't run /usr/bin/mozilla (the 1.7 binary) without having factory problems. I can run the new binary as root.

I hate software.

Make sure you link to the following plugin:

<your java install dir>/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

DO NOT link to the .../ns610/libjavaplugin_oji.so plugin


Worked for me.
