    <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>

    <para>The <application>JDK</application> comes in two flavors, a 
    precompiled binary and a source package. 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>In order to use the source code and patches, you must read and agree
    to the Sun <ulink url="http://www.java.net/jrl.csp">
    Java Research License</ulink> or optionally, the Sun 
    <ulink url="http://java.net/jiul.csp">Java Internal Use License</ulink>. 
    In addition, the source code cannot be downloaded from some countries, so 
    for users in those countries, the binary is the only option.</para>

    <para>If you plan on compiling the <application>JDK</application> source, 
    you will still need to download the binary version to bootstrap the
    <application>JDK</application> build.  You will need to download a total 
    of four files to complete the source build:
    <filename>jdk-&jdk-bin-string;-linux-i586.bin</filename>,
    <filename>jdk-&jdk-src-string;-fcs-src-b05-jrl-08_aug_2005.jar</filename> 
    (or optionally the JIUL version),
    <filename>jdk-&jdk-src-string;-fcs-bin-b05-08_aug_2005.jar</filename>, and 
    <filename>jdk-&jdk-src-string;-mozilla_headers-b05-unix-03_jun_2005.jar</filename>.

    <title>Installation of JDK</title>

    <para>Both versions will be installed in parallel. You may choose to keep
    either or both.</para>

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

<screen><userinput>sed -i "s:^PATH=.*::" jdk-&jdk-bin-string;-linux-i?86.bin &amp;&amp;
chmod -v +x jdk-&jdk-bin-string;-linux-i?86.bin &amp;&amp;
mkdir -v -p bin &amp;&amp;
ln -v -sf /bin/true bin/more &amp;&amp;
yes | PATH=$PWD/bin:$PATH ./jdk-&jdk-bin-string;-linux-i?86.bin &amp;&amp;
cd jdk&jdk-bin-version;</userinput></screen>

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

<screen role="root"><userinput>install -v -d /opt/jdk/jdk-precompiled-&jdk-bin-version; &amp;&amp;
mv -v * /opt/jdk/jdk-precompiled-&jdk-bin-version; &amp;&amp;
chown -v -R root:root /opt/jdk/jdk-precompiled-&jdk-bin-version;</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/jdk-precompiled-&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 a self-extracting
    <filename class='extension'>jar</filename> file.  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-src-string;*.jar
    do java -jar ${JAR}
done</userinput></screen>

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

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

    <para>Set/unset some variables which affect the build:</para>

<screen><userinput>export ALT_BOOTDIR="$JAVA_HOME" &amp;&amp;

unset CLASSPATH
unset CFLAGS
unset CXXFLAGS

export MAKE_VERBOSE=true &amp;&amp;
export ALT_CACERTS_FILE=${ALT_BOOTDIR}/jre/lib/security/cacerts</userinput></screen>

    <warning>
      <para>Setting CFLAGS/CXXFLAGS/LDFLAGS is guaranteed to make the build
      fail. If you are interested in optimizing the build, set 
      OTHER_CFLAGS/OTHER_CXXFLAGS/OTHER_LDFLAGS instead.  -O3, even in 
      OTHER_C{,XX}FLAGS, is known to cause a build failure.</para>
    </warning>

    <para>Additionally, if you would like to <command>make</command> in
    parallel, add the following:</para>

<screen><userinput>export HOTSPOT_BUILD_JOBS=<replaceable>[3]</replaceable></userinput></screen>

    <para>Build the <application>JDK</application> with the following
    commands. There will be a lot of messages about missing files that look like
    errors. These are caused by not meeting the expected build environment
    (Red Hat).  As long as the build doesn't stop, the messages
    are harmless.</para>

<screen><userinput>cd control/make &amp;&amp;
make &amp;&amp;
cd ../build/linux-i?86</userinput></screen>

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

<screen role="root"><userinput>cp -v -a j2sdk-image /opt/jdk/jdk-&jdk-src-version; &amp;&amp;

    <para>Restore the unprivileged user's environment using the following
    commands:</para>

<screen><userinput>unset ALT_BOOTDIR &amp;&amp;

  <sect2 role="commands">
    <title>Command Explanations</title>

    <para><command>export ALT_BOOTDIR="$JAVA_HOME"</command>: This variable sets
    the location of the bootstrap <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 ALT_DEVTOOLS_PATH="/usr/bin"</command>: This
    changes the location where the build finds the needed executables.</para>

    <para><command>export BUILD_NUMBER="blfs-&blfs-version;"</command>:
    This will help you identify the compiled version of the runtime environment
    and virtual machine by appending this information to the version
    string.</para>

    <para><command>export DEV_ONLY=true</command>: This command
    skips compiling the documentation and eliminates a dependency on
    <application>rpm</application>.</para>

    <para><command>unset JAVA_HOME</command>: This clears the
    <envar>JAVA_HOME</envar> variable as recommended by the build
    instructions.</para>

    <para><command>unset CLASSPATH</command>: This clears the
    <envar>CLASSPATH</envar> variable as recommended by the build
    instructions.</para>

    <para><command>unset CFLAGS/CXXFLAGS...</command>: These variables cause
    miscompilation of the build. Never set them.</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 MAKE_VERBOSE=true</command>: Allows the compiler
    commands to be displayed on the console.</para>

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

    <para><command>ln -sf motif21/libmawt.so 
    /opt/jdk/jdk-&jdk-src-version;/jre/lib/i386/</command>: This fixes
