To run applets, we need the Java Runtime plugin for the browser. The Java Runtime Environment (JRE) plugin for mozilla is available alongwith the JRE installation. For example, if the JRE is installed in the following location:
Then go it its plugin directory. You may find such directories:
ns4/ ns610/ ns610-gcc32/
All of them contain a file named libjavaplugin.so.
One of these is the shared object plugin that you want.
Now go to .mozilla/plugins/ directory in your home.
create a soft link of the above file here:
ln -s /usr/java/j2re1.4.2_10/plugin/i386/ns4/libjavaplugin.so .
If this happens to be the right plugin your firefox will now be able to run applets without trouble. If it's not, firefox will not run. If that happens just remove the
unlink libjavaplugin.so from the mozilla/plugins directory and try the libjavaplugin.so files in the other directories in /usr/java/j2re1.4.2_10/plugin/i386/.
One of them should work.
Bits of Learning
Learning sometimes happens in big jumps, but mostly in little tiny steps. I share my baby steps of learning here, mostly on topics around programming, programming languages, software engineering, and computing in general. But occasionally, even on other disciplines of engineering or even science. I mostly learn through examples and doing. And this place is a logbook of my experiences in learning something. You may find several things interesting here: little cute snippets of (hopefully useful) code, a bit of backing theory, and a lot of gyan on how learning can be so much fun.
