<!-- ================================================================ -->
<h3 id="overview">Package Contents</h2>

<p>
Vaadin Framework is distributed as a single JAR file. Inside the JAR you will
find:
</p>

<ul>
<li>Vaadin server and client side classes (/com)</li>
<li>Vaadin server and client side sources (/com)</li>
<li>The default widget set (/VAADIN/widgetsets)</li>
<li>Themes: Runo, Reindeer and Chameleon (/VAADIN/themes)</li>
<li>Release notes (/release-notes.html)</li>
<li>Licensing information (/license.html)</li>
</ul>

<!-- ================================================================ -->
<h3 id="dependencies">Vaadin @version@ dependencies</h2>

<p>
Vaadin uses GWT @gwt-version@ for widget set compilation. GWT can be
downloaded from <a href="http://code.google.com/webtoolkit/">http://code.google.com/webtoolkit/</a>.
GWT can also be automatically downloaded by the Vaadin Plug-in for
Eclipse. Please note that GWT @gwt-version@ requires the <i>validation-api-1.0.0.GA.jar</i>
and <i>validation-api-1.0.0.GA-sources.jar</i> files in addition to <i>gwt-dev.jar</i>
and <i>gwt-user.jar</i> for widget set compilation.

<h2 id="upgrading">Upgrading to Vaadin @version-minor@</h2>
<p>
When upgrading from an earlier Vaadin version, you must
<ul>
<li>Recompile your classes using the new Vaadin JAR. Binary
compatibility is only guaranteed for maintenance releases of
Vaadin.</li>
<li>Recompile any add-ons you have created using the new Vaadin
JAR.</li>
<li>Recompile your widget set using the new Vaadin JAR and the
newly compiled add-ons.</li>
<li>If you have extracted a theme from the Vaadin JAR, you need
to update it with the theme provided in the new Vaadin JAR.</li>
</ul>
</p>
<p>Remember also to refresh the project in your IDE to ensure that
the new version of everything is in use.</p>
<p>Using the "?debug" URL parameter you can verify that the
version of the servlet (JAR), the theme and the widgetset 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 &raquo;
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>

<p>
<b>Liferay and other portal</b> users must install the new
vaadin-@version@.jar as
<t>ROOT/WEB-INF/lib/vaadin.jar</b> in the portal. Additionally the
<tt>ROOT/WEB-INF/lib/vaadin.jar</tt> in the portal. Additionally the
contents of the <tt>VAADIN</tt> folder from the JAR 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.
</p>

<h3>Upgrading from Vaadin 6.5 or earlier</h3>
<h3>Upgrading from Vaadin 6.5 or earlier</h3>
<p>
If you are upgrading from 6.5.x or earlier, notice that Vaadin
@version@ uses GWT @gwt-version@. Upgrade your dependencies as
necessary. See <a href="#dependencies">the dependencies</a> section
for more information.

<p>
The way widget sets are created was completely changed in Vaadin 6.2.
Existing projects, where custom widgets (a custom widget set) are
used, must be migrated when upgrading to Vaadin 6.2 or later.
Projects where the default widget set is used do not need migration.
See <a

<p>
The following instructions and limitations apply when you run a Vaadin application

.

Session support must be enabled in
<tt>appengine-web.xml</tt>

</li>

<li><p>Avoid using the session for storage, usual App Engine
limitations apply (no synchronization, i.e, unreliable).</p>
</li>

<li><p>
Vaadin uses memcache for mutex, the key is of the form
<tt>_vmutex&lt;sessionid&gt;</tt>
.
</p>
</li>

<li><p>
The Vaadin <b>WebApplicationContext</b> class is serialized
separately into memcache and datastore; the memcache key is
<tt>_vac&lt;sessionid&gt;</tt>
and the datastore entity kind is
<tt>_vac</tt>
with identifiers of the type
<tt>_vac&lt;sessionid&gt;</tt>
.
</p>
</li>

<li><p>
DO NOT update application state when serving an <b>ApplicationResource</b>
(e.g <b>ClassResource</b>.<i>getStream()</i>).
</p>
</li>

<li><p>
AVOID (or be very careful when) updating application state in a <b>TransactionListener</b>
or a <b>HttpServletRequestListener</b> - they are called even when
the application is not locked and won't be serialized (e.g <b>ApplicationResource</b>),
and changes can thus go missing (it should be safe to update things
that can be safely discarded later - i.e valid only for the current
request)
</p>
</li>

<li><p>The application remains locked during uploads - a
progress bar is not possible</p>
</li>
</ul>

<li><p>Avoid using the session for storage, usual App Engine
limitations apply (no synchronization, i.e, unreliable).</p>
</li>

<li><p>
Vaadin uses memcache for mutex, the key is of the form
<tt>_vmutex&lt;sessionid&gt;</tt>.
</p>
</li>

<li>
<p> The Vaadin <b>WebApplicationContext</b> class is serialized separately into
memcache and datastore; the memcache key is <tt>_vac&lt;sessionid&gt;</tt> and
the datastore entity kind is <tt>_vac</tt> with identifiers of the type
<tt>_vac&lt;sessionid&gt;</tt>.</p>
</li>

<li>
<p>DO NOT update application state when serving an <b>ApplicationResource</b>
(e.g <b>ClassResource</b>.<i>getStream()</i>).</p>
</li>

<li>
<p>
AVOID (or be very careful when) updating application state in a
<b>TransactionListener</b> or a <b>HttpServletRequestListener</b> - they are
called even when the application is not locked and won't be serialized (e.g
<b>ApplicationResource</b>), and changes can thus go missing (it should be
safe to update things that can be safely discarded later - i.e valid only for
the current request)
</p>
</li>

<li>
<p>
The application remains locked during uploads - a progress bar is not
possible
</p>
</li>
</ul>
