[newbies] java

[Larry Landen]

I made the assumption that what I needed to download to program in java was the jre.  It's instructions helped me download and extract the file.  Then it said I needed to enable and configure it to work.  However, at this point, I get the feeling that this jre is only for Mozilla to run java things on the internet.  Following are its instructions, but I can't get past step one.  I don't know the Mozilla Installation directory.

Finally, and more important, because this seems to only work for Mozilla, I would like help getting java set up to work on my system (compiling and running programs).

Mozilla 1.4 and later

1. Go to the plugins sub-directory under the Mozilla installation directory
   cd <Mozilla installation directory>/plugins
2. In the current directory, create a symbolic link to the JRE ns7/libjavaplugin_oji.so file Type:
   ln -s <JRE installation directory>/plugin/i386/ns7/libjavaplugin_oji.so

Example:

• If Mozilla is installed in this directory:
  /usr/lib/mozilla-1.4/
• and if the JRE is installed at this directory:
  /usr/java/jre1.5.0
• Then type at the terminal to go to the browser plug-in directory:
  cd /usr/lib/mozilla-1.4/plugins
• Enter the following command to create a symbolic link to the Java Plug-in for the Mozilla browser.
  ln -s /usr/java/jre1.5.0/plugin/i386/ns7
  /libjavaplugin_oji.so .
3. Start Mozilla browser or restart it if it is already running. Note that if you have other Mozilla components (ie: Messenger, Composer, etc) running, you will need to restart them as well.
4. Go to Edit > Preferences. Under Advanced category > Select Enable Java
