Remove the Kaffe Java that comes with the distribution (Kaffe is not as mature as blackdown).

• Logon to root.
• From a command line, invoke GNU's package installer and uninstaller gnorpm
• Under the Development section, open the Languages subsection.
• Select the Kaffe package and uninstall it.

Create a base directory and expand Nuggets for Java into it:

• Open a command line and create the following directory: ~/java.
• If you haven't already done so, expand the javanuggets.zip file into it creating the ~/java/javanuggets directory.

Download the current version of blackdown's Java 2:

• Download the Linux Java Developer Kit (JDK 1.2) from one of the mirror sites. Choose the i386 branch and the filename is jdk1.2pre-v2.tar.bz2 (~19MB).
• After downloading the JDK, expand it with Linux's bunzip utility into the ~/java directory. If you need help with bunzip2, type bunzip --help. For more information about bzip2 check here.
• After expanding the JDK, rename the directory to ~/java/java.120 (use mv).
• Download the JDK HTML documentation (JDK 1.2) big bundle (~16MB) from Sun. It expands into the directory jdk1.2.0/docs. Copy the docs directory to ~/java.120/docs (you can use cp -R to do that) then discard the original expansion.

Copy Tools into Path:

• cp -R ~/java/javanuggets/tools4java.12x/* ~/java/java.122
• Makes available these commands (more info):
• applet: generates skeleton applet (source)
• application: generates skeleton application (source)
• server: invokes a web server on current directory (source)
• dump: tool to display hex dump of a file (source)
• eol: converts file to PC, Mac, or Unix line endings (source)
• sys: displays system properties object (source)
• split: divides a file into floppy sized segments (source)
• space: tool to report directory sizes (source)

Setup PATH and DISPLAY:

• If you have not conditioned your DISPLAY variable for X yet, add the following line to your .bashrc or other logon script file: DISPLAY=:0.0
• Add an entry in your path for the directory ~/java/java.120/bin.
• Or, if you are using several versions of Java, use the scripts in ~/java/javanuggets/scripts. The 12 script, shown below, sets the path to include Java 120. I copy these scripts into my home directory: cp ~/java/javanuggets/scripts/1* ~. Also, use a dot (.) and a space on the command line before the name of the script so the path adjustments in the script apply to your current shell.
• Also, in the script below, the dot (.) directory is added to the path as a personal preference for my java terminal sessions. It allows me to issue the command c rather than the command ./c to compile a java program.

    #!/bin/sh
    #
    #  Script in home directory called 12 
    #
    #  It sets a path to JDK 1.2  Use a 
    #  dot (.) to set the path in your 
    #  current shell:
    #
    #    . 12
    #
    PATH=~/java/java.120/bin:.:$PATH
