The Java plug-in is, really, a symbolic link to libnpj2.so
(I have Oracle JDK, not OpenJDK, but yours should be similar).
On my systems, /usr/lib64/mozilla
contains a plugins
|-- libnpjp2.so -> /usr/lib64/java/jre/lib/amd64/libnpjp2.so
1 directory, 3 files
Don't know exactly what Fedora does, but it ought to be similar (and, of course, my not be 64-bit and may not have library directory names like that). If you have this structure, all you need to is a symlink as above. The library name should be nearly the same as libnpjp2.so
which is the file to link to.
You need to be aware of Oracle Java plug-in security problems. Please go to http://www.linuxquestions.org/questi...3/#post4882932
and read through the links to US-CERT (there are a lot of links at US-CERT regarding the Java Plug-in and there may or may not be a problem with OpenJDK; not too clear when I read it).
Bottom line is that US-CERT recommends that the Java plug-in be disabled in any browser. It appears that you may actually have an application that requires it and you should be aware of the potential risks posed by having it enabled. This recommendation includes any version of Java Plug-in irrespective of who, when or where it was created.
Hope this helps some.
