<p>
The repositories <tt>jaxp</tt> and <tt>jaxws</tt> actually
do not contain the sources for JAXP or JAX-WS.
These products have their own open source procedures at their
<a href="http://jaxp.java.net/">JAXP</a> and
<a href="http://jax-ws.java.net/">JAX-WS</a> home pages.
The OpenJDK project does need access to these sources to build
a complete JDK image because JAXP and JAX-WS are part of the JDK.
The current process for delivery of the JAXP and JAX-WS sources
involves so called "source drop bundles" downloaded from a public
website.
There are many reasons for this current mechanism, and it is
understood that this is not ideal for the open source community.
It is possible this process could change in the future.
<br>

<li>
The JAXP or JAX-WS team prepares a new zip bundle,
places a copy in a public download area on java.net,
sends us a link and a list of CRs (Change Request Numbers).
The older download bundles should not be deleted.
It is the responsibility of the JAXP and JAX-WS team to
place the proper GPL legal notices on the sources
and do any filtering or java re-packaging for the
OpenJDK instances of these classes.
</li>
<li>
The OpenJDK team copies this new bundle into shared
area (e.g. <tt>/java/devtools/share/jdk7-drops</tt>).
Older bundles are never deleted so we retain the history.
</li>
<li>
The OpenJDK team edits the ant property file
<tt>jaxp/jaxp.properties</tt> or
<tt>jaxws/jaxws.properties</tt> to update the
base URL, the zip bundle name, and the MD5 checksum
of the zip bundle
(on Solaris: <tt>sum -c md5 <i>bundlename</i></tt>)
</li>
<li>
OpenJDK team reviews and commits those changes with the
given CRs.

</blockquote>
<h4><a name="dropusage">Using Source Drop Bundles</a></h4>
<blockquote>
<p>
The ant scripts that build <tt>jaxp</tt> and <tt>jaxws</tt>
will attempt to locate these zip bundles from the directory
in the environment variable
<tt><a href="#ALT_DROPS_DIR">ALT_DROPS_DIR</a></tt>.
The checksums protect from getting the wrong, corrupted, or
improperly modified sources.
Once the sources are made available, the population will not
happen again unless a <tt>make clobber</tt> is requested
or the <tt>jaxp/drop/</tt> or <tt>jaxws/drop/</tt>
directory is explicitly deleted.
<br>
<b>NOTE:</b> The default Makefile and ant script behavior
is to NOT download these bundles from the public http site.
In general, doing downloads
during the build process is not advised, it creates too much
unpredictability in the build process.
However, you can use <tt>make ALLOW_DOWNLOADS=true</tt> to
tell the ant script that the download of the zip bundle is
acceptable.
</p>
<p>
The recommended procedure for keeping a cache of these
source bundles would be to download them once, place them
in a directory outside the repositories, and then set
<tt><a href="#ALT_DROPS_DIR">ALT_DROPS_DIR</a></tt> to refer
to that directory.
These drop bundles do change occasionally, so the newer
bundles may need to be added to this area from time to time.

Some build variables exist to support specialized build environments and/or specialized
build products. Their use is only supported in those contexts:
<dl>
<dt><tt><a name="BUILD_CLIENT_ONLY">BUILD_CLIENT_ONLY</a></tt> </dt>
<dd>
Indicates this build will only contain the Hotspot client VM. In addition to
controlling the Hotspot build target, it ensures that we don't try to copy
any server VM files/directories, and defines a default <tt>jvm.cfg</tt> file
suitable for a client-only environment. Using this in a 64-bit build will
generate a sanity warning as 64-bit client builds are not directly supported.
</dd>
<dt><tt><a name="BUILD_HEADLESS_ONLY"></a>BUILD_HEADLESS_ONLY</tt> </dt>
<dd>
Used when the build environment has no graphical capabilities at all. This
excludes building anything that requires graphical libraries to be available.
</dd>
<dt><tt><a name="JAVASE_EMBEDDED"></a>JAVASE_EMBEDDED</tt> </dt>
<dd>
Used to indicate this is a build of the Oracle Java SE Embedded product.
This will enable the directives included in the SE-Embedded specific build
files.
</dd>
<dt><tt><a name="LIBZIP_CAN_USE_MMAP">LIBZIP_CAN_USE_MMAP</a></tt> </dt>
<dd>
If set to false, disables the use of mmap by the zip utility. Otherwise,
mmap will be used.
</dd>
<dt><tt><a name="COMPRESS_JARS"></a>COMPRESS_JARS</tt> </dt>
<dd>
If set to true, causes certain jar files that would otherwise be built without
compression, to use compression.
</dd>

<h2><a name="hints">Hints and Tips</a></h2>
<blockquote>
You don't have to use all these hints and tips, and in fact people do actually
build with systems that contradict these, but they might prove to be
helpful to some.
<ul>
<li>
If <tt>make sanity</tt> does not work, find out why, fix that
before going any further. Or at least understand what the
complaints are from it.
</li>
<li>
JDK: Keep in mind that you are building a JDK, but you need
a JDK (BOOTDIR JDK) to build this JDK.
</li>
<li>
Ant: The ant utility is a java application and besides having
ant available to you, it's important that ant finds the right
java to run with. Make sure you can type <tt>ant -version</tt>
and get clean results with no error messages.
</li>
<li>
Linux: Try and favor the system packages over building your own
or getting packages from other areas.
Most Linux builds should be possible with the system's
available packages.
</li>
<li>
Solaris: Typically you will need to get compilers on your systems
and occasionally GNU make 3.81 if a gmake binary is not available.
The gmake binary might not be 3.81, be careful.
</li>
<li>
Windows VS2010:
<ul>
<li>
Only the C++ part of VS2010 is needed.
Try to let the installation go to the default install directory.
Always reboot your system after installing VS2010.
The system environment variable VS100COMNTOOLS should be
set in your environment.
</li>
<li>
Make sure that TMP and TEMP are also set in the environment
and refer to Windows paths that exist, like <tt>C:\temp</tt>,
not <tt>/tmp</tt>, not <tt>/cygdrive/c/temp</tt>, and not <tt>C:/temp</tt>.
<tt>C:\temp</tt> is just an example, it is assumed that this area is
private to the user, so by default after installs you should
see a unique user path in these variables.
</li>
<li>
You need to use vsvars32.bat or vsvars64.bat to get the
PATH, INCLUDE, LIB, LIBPATH, and WINDOWSSDKDIR
variables set in your shell environment.
These bat files are not easy to use from a shell environment.
However, there is a script placed in the root jdk7 repository called
vsvars.sh that can help, it should only be done once in a shell
that will be doing the build, e.g.<br>
<tt>sh ./make/scripts/vsvars.sh -v10 > settings<br>
eval `cat settings`</tt><br>
Or just <tt>eval `sh ./make/scripts/vsvars.sh -v10`</tt>.
</li>
</ul>
</li>
<li>
Windows: PATH order is critical, see the
<a href="#paths">paths</a> section for more information.
</li>
<li>
Windows 64bit builds: Use ARCH_DATA_MODEL=64.
</li>
</ul>

Some of the more common problems with builds are briefly described
below, with suggestions for remedies.

<b>Corrupted Bundles on Windows:</b>
<blockquote>
Some virus scanning software has been known to corrupt the
downloading of zip bundles.
It may be necessary to disable the 'on access' or 'real time'
virus scanning features to prevent this corruption.
This type of "real time" virus scanning can also slow down the
build process significantly.
Temporarily disabling the feature, or excluding the build
output directory may be necessary to get correct and faster builds.
