    <title>Introduction to JDK</title>

    <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>

    <!-- Previously, the plugin included
    in the <application>JDK</application> binary package was unusable on LFS
    owing to incompatibilities with <application>GCC</application>-3 compiled
    browsers.  This is not the case anymore.</para> -->

    <para>The <application>JDK</application> comes in two flavors, a
    precompiled binary and a source package. You will first need to download
    and install the binary version of the <application>JDK</application>
    (you'll need to click and agree to the <quote>Sun Microsystems, Inc.
    Binary Code License Agreement</quote>). To build from the source, you
    will need to read, and agree to the Sun
    <!--<ulink url="&patch-root;/jdk-Readme.txt">-->Java Research License<!--</ulink>-->.
    You will also need to download the additional files and patches to
    complete the source build as detailed below. Note that in some countries
    you cannot download the source code.</para>

    <warning><para>Sun has recently decided not to provide JRL sources for
    the latest update versions of the JDK.  The source build instructions and
    patches are here for reference only, and contain known security
    vulnerabilities.  For more information, please see Sun Alerts

    <title>Installation of JDK</title>

    <para>The instructions below install both the binary and source versions.
    You may stop after installing the binary version or continue on installing
    the source version. You can choose to keep either or both.</para>

    <tip>
      <para>The <command>./jdk-&jdk-bin-version;-linux-i586.bin</command>
      command below unpacks the distribution into a
      <filename class='directory'>jdk&jdk-bin-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 binary <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>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>cd jdk&jdk-bin-version-string; &amp;&amp;

    <para>Recent versions of libX11 break libmawt
    when used with the Xinerama extension.  While still the
    <systemitem class="username">root</systemitem> user, apply the
    following sed to the installed binary to work around this
    problem:</para>

    /opt/jdk-bin-&jdk-bin-version;/jre/lib/i386/xawt/libmawt.so</userinput></screen>

    <para>The binary version is now installed.</para>

    <para>If you don't want to compile the source or are not in a position to
    download the source owing to license restrictions, skip ahead to the
    configuration section.</para>

    <para>Save the existing path, and append the recently installed
    <application>JDK</application>.</para>

<screen><userinput>export JAVA_HOME=/opt/jdk-bin-&jdk-bin-version; &amp;&amp;
export PATH_HOLD=${PATH} &amp;&amp;
export PATH=${PATH}:${JAVA_HOME}/bin</userinput></screen>

    <para>The source code is contained in self-extracting
    <filename class='extension'>jar</filename> files.  You
    will need to be in a windowed environment to extract the sources.
    Create a directory to store the extracted sources.  Choose the newly
    created <filename class="directory">jdk-build</filename> directory
    when prompted for the target directory.</para>

<screen><userinput>mkdir jdk-build &amp;&amp;
cd jdk-build &amp;&amp;
for JAR in ../jdk-&jdk-version-string;*.jar
    do java -jar ${JAR}

    <para>Apply all the patches downloaded above:</para>

<screen><userinput>for PATCH in ../jdk-&jdk-version-string;*.patch
    do patch -Np1 -i ${PATCH}
done</userinput></screen>

    <para>Use the following commands to apply some minor changes that
    are a little more specific to BLFS, such as lack of a gcc-2.9
    compiler, removing a broken demo, and forcing to link to shared
    libraries.  See the 'Command Explanations' section for more detail:</para>

      OTHER_C{,XX}FLAGS, is known to cause a build failure.</para></warning>


    <para>Additionally, if you would like to <command>make</command> in

<screen><userinput>export HOTSPOT_BUILD_JOBS=<replaceable>&lt;3&gt;</replaceable></userinput></screen>

    <para>Build the <application>JDK</application> with the following
    commands. There will be a few messages about missing files that look like
    errors. These are caused by not meeting the expected build environment

    are harmless.</para>

<screen><userinput>pushd control/make &amp;&amp;

    <para><command>sed -i '/^.*linux)/...</command>: This command disables
    the build of a gcc-2.9 compatible browser plugin.  LFS does not contain
    gcc-2.9, and hasn't in quite a few years.</para>

    <para><command>sed -i '/.*mtrace.*/...</command>: This command disables
    building of the broken 'waiters' demo.</para>

    <para><command>sed -i 's/= true/= false/'...</command>: This command
    forces the compiler to link against the standard C libraries
    dynamically.</para>

    <para><command>export ALT_BOOTDIR=${JAVA_HOME}</command>: This variable sets
    the location of the bootstrap <application>JDK</application>.</para>

    <para><command>export ALT_CACERTS_FILE...</command>: Specifies the
    certificate file to use (from the installed binary
    <application>JDK</application>).</para>

    <para><command>export ALT_MOZILLA_HEADERS_PATH=${PWD}/share/plugin/</command>:
    This tells the build exactly where to find the
    <application>Mozilla</application> headers.  This has changed since the
    previous version and is not mentioned in the installation documentation
    included with the package source.</para>

    <para><command>export MILESTONE="03-BLFS"</command>: This appends
    the string '03-BLFS' to the buld number.  'internal' is
    unconditionally added if MILESTONE is unset.  This is similar
    to the format used by Sun for the official release.</para>

    <para><command>export BUILD_NUMBER="b05"</command>:
    This will help you identify the compiled version of the runtime
    environment and virtual machine by appending this information to
    the version string. This is the same build number used by Sun to
    identify the official release.</para>

    <para><command>export INSANE=true</command>: The certified platform for the
    build is Redhat Enterprise Advanced Server 2.1. This variable ensures that
    all the errors related to compiling on a non-certified platform will be
    displayed as warnings instead of errors.</para>

    <para><command>export DEV_ONLY=true</command>: This command
    skips compiling the comparison build.</para>

    <para><command>export SKIP_FASTDEBUG_BUILD=true</command>: This command
    skips building of the debug version.  Omit this command if you need
    to build the fastdebug target.</para>

    <para><command>unset JAVA_HOME CLASSPATH CFLAGS CXXFLAGS LDFLAGS</command>:
    These variables cause miscompilation of the build. Never set them.</para>

    <para><command>ln -sf xawt/libmawt.so
