Debian lenny’s iceweasel is old, thus I download and install the tar-zip version from mozilla. All plugins from iceweasel are working fine except java. Java applet did not work in the Firefox 3.6.2 that I’m using. Looking at the plugin list, java is missing. Following the instruction from mozilla didn’t help. After searching the web for some time, finally, I found the solution here.
The plugin file libjavaplugin_oji.so only work in Firefox 3.5 and below. For Firefox 3.6, the correct plugin file is libnpjp2.so. In debian lenny, it is located at /usr/lib/jvm/java-6-sun-220.127.116.11/jre/lib/i386/libnpjp2.so.
Simply do this:
$ cd /path_where_firefox_is_installed/
$ cd plugins
$ ln -s /usr/lib/jvm/java-6-sun-18.104.22.168/jre/lib/i386/libnpjp2.so
