</p>
<h3 id="limitations">Limitations</h3>
<ul>
<li>It is currently not possible to specify <tt>font-size</tt>
as <tt>em</tt> or <tt>%</tt>, or layout component sizes
with <tt>em</tt> (<a
href="http://dev.vaadin.com/ticket/10634">#10634</a>)
</li>
<li>Push is currently not supported in portals (See <a
href="http://dev.vaadin.com/ticket/11493">#11493</a>)
</li>
<li>HTTP session can not be invalidated while using
push (<a href="http://dev.vaadin.com/ticket/11721">#11721</a>)
</li>
<li>Cookies are not available while using push (<a
href="http://dev.vaadin.com/ticket/11808">#11808</a>)
</li>
<li>Not all proxies are compatible with websockets. If
you are using push with an incompatible proxy you might
have to force the transport mode to streaming. Some
proxies have problems with streaming also - you need to
ensure that the proxy does not buffer responses for HTTP
streaming to work.</li>
</ul>

</p>
<h2 id="vaadin">Vaadin Installation</h2>
<p>
<b>Vaadin</b> is a Java framework for building modern web
applications that look great, perform well and make you and
your users happy. <b>Vaadin</b> is available under the
Apache License, Version 2.0 (see the
<tt>license.html</tt>
in the Vaadin ZIP or JAR package).
</p>
<p>
The easiest ways to install <b>Vaadin</b> are:
</p>
<ul>
<li>If using Maven, define it as a dependency or use
any of the available archetypes (only <tt>vaadin-application</tt>
is available for Vaadin 7 at the time of this release)
to create a new project
</li>
<li>If using Eclipse, use the Vaadin Plugin for
Eclipse, which automatically downloads the Vaadin
libraries. To use this prerelease version, the plugin
should be installed from the experimental update site (<tt>http://vaadin.com/eclipse/experimental</tt>).
</li>
</ul>
<p>
It is also available as a ZIP package downloadable from <a
href="http://vaadin.com/download">Vaadin Download
page</a>.
</p>
<h3 id="package">Package Contents</h3>
<p>Inside the ZIP installation package you will find:</p>
<ul>
<li>Separate server-side (<tt>vaadin-server</tt>) and
client-side (<tt>vaadin-client</tt>, <tt>vaadin-client-compiler</tt>)
development libraries
</li>
<li>Precompiled widget set (<tt>vaadin-client-compiled</tt>)
for server-side development
</li>
<li>Shared library (<tt>vaadin-shared</tt>) for both
server- and client-side libraries
</li>
<li>Built-in themes (<tt>vaadin-themes</tt>) and the
theme compiler (<tt>vaadin-theme-compiler</tt>)
</li>
<li>Dependency libraries provided under the <tt>lib/</tt>
folder
</li>
</ul>
<p>
See the
<tt>README.TXT</tt>
in the installation package for detailed information about
the package contents. <a href="http://vaadin.com/book">Book
of Vaadin</a> (for Vaadin 7) gives more detailed
instructions.
</p>
<p>
For server-side development, copy the
<tt>vaadin-server</tt>
,
<tt>vaadin-client-compiled</tt>
,
<tt>vaadin-shared</tt>
,
<tt>vaadin-theme-compiler</tt>
, and
<tt>vaadin-themes</tt>
from the main folder and the dependencies from the
<tt>lib</tt>
folder to the
<tt>WEB-INF/lib</tt>
folder of your Vaadin project. (The
<tt>vaadin-client-compiled</tt>
is necessary if you do not wish to compile the widget set by
your own, which you need to do if you use almost any add-on
components.)
</p>
<p>
For pure client-side development, you only need the
<tt>vaadin-client</tt>
and
<tt>vaadin-client-compiler</tt>
JARs, which should be put to a non-deployed project library
folder, such as
<tt>lib</tt>
. You also need them if you compile the widget set for any
reason, such as using Vaadin add-ons, or create new
server-side components integrated with client-side widgets.
</p>
<h2 id="migrating">Migrating from Vaadin 6</h2>
<p>
All Vaadin 6 applications need some changes when migrating
to Vaadin 7. The most obvious changes are in the
application/window API and require extending either <b>UI</b>
or <b>UI.LegacyApplication</b> instead of <b>Application</b>.
A detailed list of migration changes are given in the <a
href="https://vaadin.com/wiki/-/wiki/Main/Migrating+from+Vaadin+6+to+Vaadin+7">Vaadin
7 Migration Guide</a>.
</p>
<p>Any custom client-side widgets need to be ported to use
the new client-server communication API, or the Vaadin 6
compatibility API.</p>
<p>
Vaadin 6 add-ons (ones that contain widgets) do not work in
Vaadin 7 - please check the add-ons in <a
href="http://vaadin.com/directory/">Vaadin Directory</a>
for Vaadin 7 support.
</p>
<h2 id="dependencies">Vaadin @version@ Dependencies</h2>
<p>When using Maven, Ivy, Gradle, or other dependency
management system, all Vaadin dependencies are downloaded
automatically. This is also the case when using the Vaadin
Plugin for Eclipse.</p>
<p>
The Vaadin ZIP installation package includes the
dependencies in the
<tt>lib</tt>
subfolder. These need to be copied to the
<tt>WEB-INF/lib</tt>
folder of the web application that uses Vaadin.
</p>
<p>
The dependencies are listed in the <a href="license.html">Licensing
description</a>. Some are explicit dependencies packaged and
distributed as separate JARs, while some are included inside
other libraries.
</p>
<h3>Bean Validation</h3>
<p>
If you use the bean validation feature in Vaadin 7, you need
a Bean Validation API implementation. You need to install
the implementation JAR in the
<tt>WEB-INF/lib</tt>
directory of the web application that uses validation.
</p>
<h2 id="upgrading">Upgrading to Vaadin @version-minor@</h2>
<h3>Upgrading the Eclipse Plugin</h3>
<p>
Vaadin 7 requires that you use a compatible version of the
Vaadin Plugin for Eclipse. The stable version of the plugin
is available from the
<tt>http://vaadin.com/eclipse</tt>
update site. Please see the <a
href="https://vaadin.com/book/vaadin7/-/page/getting-started.eclipse.html#getting-started.eclipse.update">section
about updating the plugin</a> in the Book of Vaadin and the
<a href="http://vaadin.com/eclipse">installation
instructions at the download site</a> for more details.
</p>
<p>
You can also use the <i>experimental</i> Vaadin Plugin for
Eclipse. Its update site is
<tt>http://vaadin.com/eclipse/experimental</tt>
.
</p>
<h3>General Upgrading Instructions</h3>
<p>When upgrading from an earlier Vaadin version, you must:
</p>
<ul>
<li>Recompile your classes using the new Vaadin
version. Binary compatibility is only guaranteed for
maintenance releases of Vaadin.</li>
<li>Recompile any add-ons you have created using the
new Vaadin</li>
<li>Unless using the precompiled widget set, recompile
your widget set using the new Vaadin version</li>
</ul>
<p>Remember also to refresh the project in your IDE to
ensure that the new version of everything is in use.</p>
<p>
By using the "
<tt>?debug</tt>
" URL parameter, you can verify that the version of the
servlet, the theme, and the widget set all match.
</p>
<p>
<b>Eclipse</b> users should always check if there is a new
version of the Eclipse Plug-in available. The Eclipse
Plug-in can be used to update the Vaadin version in the
project (Project properties » Vaadin).
</p>
<p>
<b>Maven</b> users should update the Vaadin dependency
version in the
<tt>pom.xml</tt>
unless it is defined as
<tt>LATEST</tt>
. You must also ensure that the GWT dependency uses the
correct version and recompile your project and your widget
set.
</p>
<p>
<b>Liferay and other portal</b> users must install the
Vaadin libraries in
<t>ROOT/WEB-INF/lib/</b> in the portal (and remove a
possibly obsolete older <tt>vaadin.jar</tt>). Additionally,
the contents of the <tt>vaadin-client-compiled</tt> and <tt>vaadin-themes</tt>
must be extracted to the <tt>ROOT/html/VAADIN</tt> directory
in the Liferay installation. If your portal uses custom
widgets, install the latest version of <a
href="http://vaadin.com/directory#addon/vaadin-control-panel-for-liferay">Vaadin
Control Panel for Liferay</a> for easy widget set
compilation - when it is available - the add-on is not
compatible with Vaadin @version@ at the time of this Vaadin
release. <!-- TODO: Remove note when done --></t>

Notes and Limitations for Google App Engine
</h4>
</h2>
<p>The following instructions and limitations apply when you
run a Vaadin application under the Google App Engine.</p>
<ul>
<li>
<p>
Applications must use <b>GAEVaadinServlet</b>
instead of <b>VaadinServlet</b> in
<tt>web.xml</tt>
.
</p>
</li>
<li>
<p>
Session support must be enabled in
<tt>appengine-web.xml</tt>
:
</p> <pre> <sessions-enabled>true</sessions-enabled></pre>
</li>
<li>
<p>Avoid using the session for storage, usual App
Engine limitations apply (no synchronization, that
is, unreliable).</p>
</li>
<li>
<p>
Vaadin uses memcache for mutex, the key is of the
form
<tt>_vmutex<sessionid></tt>
.
</p>
</li>
<li>
<p>
The Vaadin <b>VaadinSession</b> class is serialized
separately into memcache and datastore; the memcache
key is
<tt>_vac<sessionid></tt>
and the datastore entity kind is
<tt>_vac</tt>
with identifiers of the type
<tt>_vac<sessionid></tt>
.
</p>
</li>
<li>
<p>
DO NOT update application state when serving an <b>ConnectorResource</b>
(such as <b>ClassResource</b>.<i>getStream()</i>).
</p>
</li>
<li>
<p>The application remains locked during uploads - a
progress bar is not possible</p>
</li>
</ul>
<p>
