<h2 id="overview">Package Contents</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 2 license
(see license.html).
</p>
<p>
<b>Vaadin</b> is distributed as a single JAR file. Inside the JAR you
will find:
<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>
</p>
<!-- <h2 id="security-fixes">Security fixes in Vaadin @version-minor@</h2>-->
<h2 id="enhancements">Enhancements in Vaadin @version-minor@</h2>
<p>
<b>TODO: Enhancements</b>
</p>
<p>TOdO: Enhancements.</p>
<h2 id="fixes">Fixes in Vaadin @version@</h2>
<p>
TODO: Ticket list
</p>
<p>
The <a href="http://dev.vaadin.com/query?status=closed&type=defect&milestone=Vaadin%20@version@">full
details of the defects</a> can be found at dev.vaadin.com.
</p>
<h2 id="backwardsincompatibilities">Backwards incompatible
changes in Vaadin @version-minor@</h2>
<p>VerticalSplitPanel and HorizontalSplitPanel position is now a float instead of an int to enable defining an exact position when using percentages.</p>
<h2 id="dependencies">Vaadin @version@ dependencies</h2>
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 »
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>
<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
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.
<h3>Upgrading from Vaadin 6.5 or earlier</h3>
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>
<h3 id="widgetupgrade">Upgrading from Vaadin 6.1 or earlier</h3>
<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
href="http://vaadin.com/download/release/6.2/6.2.0/release-notes.html">Vaadin
6.2.0 release notes</a> for more details.
</p>
<h4 id="gae">Notes and Limitations for Google App Engine</h4>
<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>GAEApplicationServlet</b> instead of <b>ApplicationServlet</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, i.e, 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>WebApplicationContext</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>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>
<p>
For other known problems, see open tickets at developer site <a
href="http://dev.vaadin.com/">dev.vaadin.com</a>.
