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

60
61	<para>The <application>JDK</application> comes in two flavors, a
62	precompiled binary and a source package. You will first need to download
63	and install the binary version of the <application>JDK</application>
64	(you'll need to click and agree to the <quote>Sun Microsystems, Inc.
65	Binary Code License Agreement</quote>). To build from the source, you
66	will need to read, and agree to the Sun
67	<!--<ulink url="&patch-root;/jdk-Readme.txt">-->Java Research License<!--</ulink>-->.
68	You will also need to download the additional files and patches to
69	complete the source build as detailed below. Note that in some countries
70	you cannot download the source code.</para>
71
72	<warning><para>Sun has recently decided not to provide JRL sources for
73	the latest update versions of the JDK. The source build instructions and

190
191	<para>The instructions below install both the binary and source versions.

193	the source version. You can choose to keep either or both.</para>
194
195	<tip>
196	<para>The <command>./jdk-&jdk-bin-version;-linux-i586.bin</command>
197	command below unpacks the distribution into a
198	<filename class='directory'>jdk&jdk-bin-version-string;</filename>
199	directory. You will be required to view, and then accept (by entering a
200	<keycap>y</keycap> keypress), a license agreement before any files are
201	unpacked. If you are scripting (automating) the build, you'll need to
202	account for this. There is information about automating build commands
203	in the <xref linkend="automating-builds"/> section of Chapter 2. Towards
204	the end of this section, specific information for automating this type of
205	installation is discussed.</para>

207
208	<para>Normally in BLFS, the files are unpacked into a subdirectory

219	<note><para>The installation will end with a message
220	"./jdk-&jdk-bin-version;-linux-i586.bin: line 43: 20283 Aborted" as
221	javaprefix is unset in the environment. This is by design as
222	<application>GTK+</application> may not be installed during the
