System error?:: Success Removing the Java plugin fixes the problem, but of course I can't run Java applets. If I try to use either the Sun 1.4.2 Java plugin or the Blackdown 1.4.2 plugin, I get the error. I'm running Red Hat Linux 7.3 with a 2.4.20 kernel and glibc 2.2.5. The Sun plugin worked when I was using Mozilla 1.4. I installed j2sdk-1.4.2-rc1-linux-i586-gcc2.95.bin. Reproducible: Always Steps to Reproduce: 1. Start Mozilla with a link to the Java plugin 2. 3. Actual Results: "INTERNAL ERROR on Browser End: No manager for initializing factory? System error?:: Success Expected Results: Run normally with support for Java plugins.

BTW, bug 212016 is a similar bug, but wasn't enlightening.

you should use plain Sun's JRE 1.4.2_03 and the ns610-gcc322/ plug-in (your JRE seems to have been compiled with GCC 2.95, hence it won't work with Mozilla 1.6b, compiled with GCC 3.2).

Ok, I upgraded from Sun's JDK 1.4.2 to 1.4.2_03 and made a link from the plugins directory to /usr/java/j2sdk1.4.2_03/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so. Note that the link is to ns610-gcc32, not ns610-gcc322. Mozilla now displays LoadPlugin: failed to initialize shared library /usr/java/j2sdk1.4.2_03/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so [libgcc_s.so.1: cannot open shared object file: No such file or directory] I confess to being confused by gcc library version issues. I searched Google for libgcc_s.so.1, and found an RPM named libgcc-3.0.4-1.i386.rpm. Is it safe to install it?

not sure which distro you're using, see http://mozilla.org/releases/mozilla1.6b/known-issues.html#java for more: "The Sun Java Plugin is compatible with modern Linux versions like Red Hat 8 or later and SuSE 8.1 or later (the plugin depends on a newer version of libgcc_s.so, installing the GCC supplements for Red Hat 7.3 -GCC 3.1 Compiler Suite for Red Hat Linux 7.3 - may allow for some older Red Hat Linux to run the plugin)" see also http://plugindoc.mozdev.org/faqs/java.html: "If you are using an older Linux distribution, you may need to install the gcc3 support libraries, as the gcc 3.2 version of the Java plugin requires libgcc_s.so.1 to operate. You may be able to find packages using Google."

Yeah, I saw that. I wasn't able to find the "Red Hat 7.3 -GCC 3.1 Compiler Suite for Red Hat Linux 7.3". I'm scared that installing libgcc-3.0.4-1.i386.rpm will cabbage my system - future use of the linker will go nuts or I'll just die in dependency hell. I'm giving up. Please mark this bug appropriately. Thank you very much for your help.
