    <para>The <application>JDK</application> package contains
    Sun's <application>Java</application> development environment. This is
    useful for developing <application>Java</application> programs and provides
    the runtime environment necessary to run <application>Java</application>
    programs.  It also includes a plug-in for browsers so that they can be
    <application>Java</application> aware.</para>

    <title>Installation of JDK</title>

    <tip>
      <para>The <command>./jdk-&jdk-bin-version;-linux-i586.bin</command>
      command below unpacks the distribution into a
      <filename class='directory'>jdk&jdk-version-string;</filename>
      directory.  You will be required to view, and then accept (by entering a
      <keycap>y</keycap> keypress), a license agreement before any files are
      unpacked. If you are scripting (automating) the build, you'll need to
      account for this. There is information about automating build commands
      in the <xref linkend="automating-builds"/> section of Chapter 2. Towards
      the end of this section, specific information for automating this type of
      installation is discussed.</para>
    </tip>

    <para>Normally in BLFS, the files are unpacked into a subdirectory
    and the starting point for the installation procedures is that
    location.  For this application only, start in the directory where all
    the downloaded files are located.</para>

    <para>Install the <application>JDK</application> with the
    following commands:</para>

<screen><userinput>chmod 755 jdk-&jdk-bin-version;-linux-i586.bin &amp;&amp;
./jdk-&jdk-bin-version;-linux-i586.bin</userinput></screen>

    <note><para>The installation will end with a message
    "./jdk-&jdk-bin-version;-linux-i586.bin: line 43: 20283 Aborted" as
    javaprefix is unset in the environment.  This is by design as
    <application>GTK+</application> may not be installed during the
    installation, however, the installation will still exit with a zero error
    value if scripting the build.</para></note>
