<li><a href="#requirements">Requirements</a></li>
</ul>
<p>Vaadin @version@ is an update release for Vaadin 6. In addition to various fixes, it
contains a number of significant enhancements.</p>
<ul>
<li>Widget set definition and component-to-widget mapping has been redesigned</li>
<ul>
<li>Reuse of widgets is now much easier, as it is easier to package and use widget
set JARs and otherwise combine widget sets.</li>
<li>A widget set definition class is no longer used. Java code needed for widget
instantiation and client-server mapping is automatically generated by GWT
compiler. For a common Vaadin user, Widgetset is now only a GWT module definition
file (.gwt.xml).</li>
<li>Server-side component is mapped to a client-side widget with an annotation:
<pre>@ClientWidget(com.vaadin.demo.colorpicker.gwt.client.ui.VColorPicker.class)
public class ColorPicker extends AbstractField {</pre>
</li>
<li>The <tt>getTag()</tt> method is no longer needed</tt></li>
<li>The Vaadin Plugin for Eclipse can create new widget stubs, define the mapping,
and create widget set definition files (<tt>.gwt.xml</tt>).</li>
<li>See <tt>WebContent/docs/example-source/build-widgetset.xml</tt> for an example
on how you can compile widget sets and widget set JARs with Ant.</li>
<li>A widget set builder allows automatic generation and maintenance of widget
configurations, making use of widget set JARs easier.</li>
<li>See <a href="#widgetupgrade">notes below</a> for upgrading widget set
definitions and widget mappings from earlier version of Vaadin 6.</li>
</ul>
<li>Other enhancements to development of new components</li>
<ul>
<li>On the server-side:</li>
<ul>
<li>Listeners for custom client side events are now easier to implement with
<tt>ReflectTools.findMethod()</tt> and <tt>addListener(String eventIdentifier,
Class<?> eventType, Object target, Method method)</tt> methods. The latter
automatically informs the client-side that a listener is registered on server side)</li>
</ul>
<li>On the client-side:</li>
<ul>
<li>Ability to check if a listener is registered on the server-side</li>
<li>Typed arrays and maps can now be sent to server with <tt>updateVariable()</tt>
<ul>
<li><b>Note!</b> This change affects existing custom components that send object arrays to the server.
Previously Object[] sent from client to server were converted into String[] on server side.
This invalid behavior is now fixed and an Object[] sent from client side is an
Object[] on server side.</li>
</ul>
</li>
</ul>
</ul>
<li>Portlet 2.0 (JSR 268) support</li>
<ul>
<li>A separate servlet for each portlet is no longer needed.
(no separate servlet, no session problems, portlet-to-portlet communication, etc)</li>
</ul>
<li>OSGi support</li>
<ul>
<li>Vaadin now works as a OSGi bundle.</li>
</ul>
<li>Enhanced sorting of <b>IndexedContainer</b> and <b>BeanItemContainer</b></li>
<ul>
<li>Custom sort methods can now be used to sort container contents.</li>
</ul>
<li>Improved event support</li>
<ul>
<li>A generic method for sending client side events to the server only when a listener has been registered for the event</li>
<li>All included layouts (<b>AbsoluteLayout</b>,<b>CssLayout</b>,<b>HorizontalLayout</b>,<b>GridLayout</b>,<b>VerticalLayout</b>) support click listeners.</li>
<li>Click events for <b>Panel</b> and <b>Embedded</b>.</li>
<li>Focus and blur events for <b>DateField</b>, <b>TextField</b>, and <b>Select</b></li>
</ul>
<li>JavaScript execution with <tt>Window.excecuteJavaScript()</tt></li>
<ul>
<li>Using excecuteJavaScript() you can execute javascript directly from the server side. This can be used e.g. for integration with other systems or implementing print functionality (window.print()). </li>
</ul>
<li>Additional Maven archetypes</li>
<ul>
<li><b>vaadin-archetype-clean</b> with a dependency to Vaadin and a minimal application skeleton, no client side widgets</li>
<li><b>vaadin-archetype-widget</b> for creation of Vaadin 6.2 widget packages</li>
<li><b>vaadin-archetype-sample</b> has been updated for Vaadin 6.2 - use version 1.0.x for earlier Vaadin versions</li>
</ul>
<li>Maven Vaadin plugin</li>
<ul>
<li><b>vaadin-maven-plugin</b> can automatically update Vaadin 6.2 widgetsets based on Maven dependencies using the goal <tt>update-widgetset</tt></li>
</ul>
<li><b>HttpServletRequestListener</b></li>
<ul>
<li>Similar to <b>TransactionListener</b> but only related to a single Application. Called before and after every servlet request and provides access to <b>HttpServletRequest</b> and <b>HttpServletResponse</b>.</li>
</ul>
<li><b>PortletRequestListener</b>
<ul>
<li>Similar to <b>HttpServletRequestListener</b> but for portlets. Called before and after every portlet request and provides access to <b>PortletRequest</b> and <b>PortletResponse</b>.</li>
</ul>
<li>Enhancements to various components:</li>
<ul>
<li><b>Window</b>: Additional control over a sub window: close and drag prevention.</li>
<li><b>Tree</b>: Item style generator enabling styling of inidividual tree items. Rendering optimizations.</li>
<li><b>Tabsheet</b>: Tabs can be marked as closable. The new <b>CloseHandler</b> can be used to ask for confirmation, prevent closing etc.</li>
<li><b>SplitPanel</b>: Double clicking the splitter sends an event which can be handled on server-side.</li>
<li><b>MenuBar</b>: Many enhancements: Individual items can be styled, support for separators, disabling of items, visibility of items.</li>
<li><b>DateField</b>: Support for lenient/non-lenient mode. A <b>DateField</b> is now by default in non-lenient mode (only accepts valid dates). </li>
</ul>
<li>Automatic integration tests</li>
<ul>
<li>All Vaadin builds are now automatically tested on all supported servers.</li>
</ul>
<li>Dozens of other small enhancements and bug fixes</li>
</ul>
<p>Problem fixes and enhancements planned for upcoming releases can be found from the <a
href="http://dev.vaadin.com/roadmap">Vaadin Roadmap</a> in Vaadin Trac.</p>
<p>As always, when upgrading from an earlier version, you should recompile any custom
widget sets and refresh your project in Eclipse. If you are upgrading from earlier than
6.2.0, notice that Vaadin 6.2 uses GWT 1.7.0 (included in the installation package). See
<a href="#upgrading">General Upgrade Notes</a> for more details on upgrading.</p>
<h2><a name="widgetupgrade">Upgrading from an Earlier Vaadin 6 version</a></h2>
<p>
The widgetsets have been renewed and simplified in Vaadin 6.2 as described above. Existing projects
where custom widgets (a custom widgetset) are used must be migrated when upgrading to Vaadin 6.2.
Projects where the default widgetset is used do not need migration. For most
projects this should be a quite painless upgrade.
</p>
<p>
For applications where custom widgets are used (also applicable to widget projects):
<ul>
<li>Remove the <i>getTag()</i> method from all components and replace it with a @ClientWidget(VClientSideWidget.class) annotation. Tag names are no longer used to map the server-side and client-side part of the component. This is done automatically using the @ClientWidget annotation.</li>
<li>Remove the <tt>WidgetSet.java</tt> file. This file is no longer needed as the mapping between server and client side is done automatically using @ClientWidget.</li>
</ul>
</p>
<p>
If you are using widgets from another project (typically in a separate JAR file):
<ul>
<li>Acquire a new JAR which is compatible with Vaadin 6.2 and add it to WEB-INF/lib. The widgetset compiler will automatically include the jar in your widgetset.gwt.xml during compilation if using Eclipse. For Ant/Maven you need to specify the location of the widgetset jars that you want to include in the application widgetset.</li>
</ul>
</p>
<p>
If you package a widget set as a JAR for use in other projects:
<ul>
<li>Replace getTag() with @ClientWidget and remove the <tt>WidgetSet.java</tt> as described above.</li>
<li>Add a "Vaadin-Widgetsets: <fully qualified name of widgetset>" (e.g. "Vaadin-Widgetsets: com.example.widgetset.mywidgetset") row to META-INF/MANIFEST.MF in the jar file. This enables the widgetset compiler to automatically detect and include the widgetset in other projects.</li>
</ul>
</p>
<h2><a name="upgrading">General Upgrade Notes</a></h2>
<p>When upgrading from an earlier version of the Vaadin library, you should always do the following:</p>
<ol>
<li>Install the new Vaadin JAR to your project</li>
<ul>
<li>If using the Vaadin Plugin in Eclipse, download and select the new version in project preferences.</li>
</ul>
<li>Install new GWT JARs if the GWT version has changed</li>
<ul>
<li>The Eclipse plugin will automatically download the new GWT and update launch configurations and the project build path when you update the Vaadin version.</li>
</ul>
<li>If you have custom widget sets, recompile them with the new Vaadin library using the included GWT compiler</li>
<li>If using the Eclipse IDE:
<ol type="a">
<li>Refresh the Eclipse project by selecting the project folder and pressing <strong>F5</strong></li>
<li>Restart the application server</li>
</ol>
</ol>
<p>Using the Vaadin project facet in the Eclipse IDE does the steps 1 and 2 automatically.</p>
<h2><a name="upgrading-tk5">Instructions for Upgrading from IT Mill Toolkit 5</a></h2>
<p>While the Vaadin 6 API is otherwise mostly backward-compatible with IT Mill Toolkit 5.4, the
change of the product name has made it necessary to reflect it in the Java package names,
some name prefixes, and some other details.</p>
<h3>Server-side Upgrade Instructions</h3>
<ul>
<li>Java Package names have changed:</li>
<ul>
<li>In all Java files using IT Mill Toolkit, rename package prefix <tt>com.itmill.toolkit</tt> → <tt>com.vaadin</tt></li>
<li>You also need to update the <tt>web.xml</tt> deployment descriptor:</li>
<ul>
<li>The servlet class is now <strong>com.vaadin.terminal.gwt.server.ApplicationServlet</strong>.</li>
</ul>
</ul>
<li>Changes in themes:
<ul>
<li>Rename <tt>WebContent/ITMILL</tt> → <tt>WebContent/VAADIN</tt></li>
<ul>
<li>If you have extracted the built-in themes and widgetsets in IT Mill Toolkit JAR to the folder to have them served statically by the server, remove the old content and re-extract from Vaadin JAR.</li>
<li>This may require changes to build scripts for custom widgetsets, as well as to any code that relies on the old naming (it is discouraged but possible).</li>
</ul>
<li>The new "<tt>reindeer</tt>" theme is the default theme in Vaadin; the old
"<tt>default</tt>" theme in IT Mill Toolkit 5 has been renamed as "<tt>runo</tt>"</li>
<ul>
<li>There is no longer a theme with name "<tt>default</tt>"</li>
<li>In your custom theme, replace:
<table><tr><td></td><td><tt>@import "../default/styles.css";</tt></td></tr>
<tr><td align="right">→</td><td><tt>@import "../reindeer/styles.css";</tt></td><td>if you wish to use the new default theme,</td></tr>
<tr><td align="right">or →</td><td><tt>@import "../runo/styles.css";</tt></td><td>if you wish to use the old default theme.</td></tr></table></li>
<li>Use the new default theme with <tt>setTheme("reindeer")</tt> and the old one with <tt>setTheme("runo")</tt>.</li>
</ul>
<li>CSS class names now start with "<tt>v-</tt>" prefix instead of "<tt>i-</tt>"</li>
<ul>
<li>Search and replace "<tt>.i-</tt>" → "<tt>.v-</tt>" in custom themes </li>
</ul>
</ul>
<li>Embedding Vaadin applications in web pages:</li>
<ul>
<li>The name of the JavaScript variable used for launching applications has changed from "<tt>itmill.toolkitConfigurations</tt>" → "<tt>vaadin.vaadinConfigurations</tt>"</li>
</ul>
<li>Other changes in naming:</li>
<ul>
<li>Rename references to <tt>translateToolkitUri()</tt> → <tt>translateVaadinUri()</tt> method in <strong>ApplicationConnection</strong> class.
</ul>
</ul>
<h3>Client-side Upgrade Instructions</h3>
<p>The following changes are relevant only if you have developed or integrated custom
client-side widgets with Google Web Toolkit (GWT).</p>
<ul>
<li>GWT 1.7 is required for compiling custom widgets (optional)</li>
<ul>
<li>You need to upgrade GWT</li>
<li>The GWT Compiler class name has changed:</li>
<ul>
<li>Replace <tt>com.google.gwt.dev.GWTCompiler</tt> → <tt>com.google.gwt.dev.Compiler</tt> in your widget set build script (Ant) or launch configuration (Eclipse).</li>
<li>Replace the output directory argument for the compiler with the new WAR output argument: <tt>-out</tt> → <tt>-war</tt>. The directory parameter for the argument remains unchanged.</li>
</ul>
</ul>
<li>The "<strong>I</strong>" (IT Mill) prefix in client-side widget classes has been changed to "<strong>V</strong>" (Vaadin), for example: <strong>IButton</strong> → <strong>VButton</strong>.</li>
<li>Rename <strong>IToolkitOverlay</strong> → <strong>VOverlay</strong>
</ul>
<h2><a name="gae">Notes and Limitations for Google App Engine</a></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>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>
<h2><a name="oophm">Package for the experimental GWT Out-of-Process Hosted Mode</a></h2>
<p>We provide a separate (platform independent) installation package
(<tt>vaadin-oophm-@version@.tar.gz</tt>) for the
experimental Out of Process Hosted Mode (OOPHM) of GWT, which allows
debugging client-side code in GWT Hosted Mode with a regular web
browser. Using the OOPHM requires installing a browser plugin (available
for Mozilla Firefox, IE, and WebKit). See the manual section on OOPHM
for more details.</p>
<p>The Linux version of GWT Hosted Mode Browser is no longer compatible with Vaadin (<a
href="http://dev.vaadin.com/ticket/2299">#2299</a>), so the OOPHM is the only option for
debugging in hosted mode in Linux.</p>
<p>The GWT 1.7.0 version included in the OOPHM package is a custom
build from GWT trunk and is not 100% compatible with the official GWT
1.7.0 release (<a href="http://dev.vaadin.com/ticket/3270">#3270</a>).</p>
<p>As the OOPHM package is experimental and because there are
differences between the version packaged with Vaadin and the official
version of GWT, you should use it only for debugging purposes during
development. For production use, and generally when you absolutely do
not need to debug using OOPHM, you should compile your custom widget
sets with the regular Vaadin package for your platform.</p>
<h2><a name="known-problems">Important known problems in Vaadin @version@</a></h2>
<ul>
<li><p><a href="http://dev.vaadin.com/ticket/1155">#1155</a>:
Uncompressing the installation package fails in Windows if using the
default Zip uncompression. Uncompression gives (in Windows Vista) an
error message about too long filenames, and a more obscure message in
other versions of Windows. Workaround: use <a
href="http://www.7-zip.org/">7-Zip</a> or some other good unzip
program for Windows.</p></li>
<li><p><a href="http://dev.vaadin.com/ticket/2299">#2299</a>: The
Hosted Mode Browser does not work in Linux for debugging client-side
GWT code. You need to install the experimental OOPHM package instead
(see above) for development. For production, you should use the regular
package for Linux.</p></li>
<li>
<p><a href="http://dev.vaadin.com/ticket/3716">#3716</a>: OOPHM
Hosted Mode browser does not work in Firefox 3.0 with <tt>vaadin-oophm-6.x.x/gwt/plugins/firefox3/oophm-xpcom-ff3.xpi</tt>.
As a workaround, the old <tt>oophm.xpi</tt> plugin provided in the IT
Mill Toolkit 5.3.0 package works just fine with Vaadin OOPHM 6.1.4 and
later.</p>

<h2><a name="requirements">Requirements</a></h2>
<p>Vaadin is available for the following operating systems:</p>
<ul>
<li>Windows (see the Zip installation notice above)</li>
<li>Linux</li>
<li>Mac OS X Tiger (mac) or Leopard (leopard)</li>
<li>Other UNIX operating systems, such as Sun Solaris, using the installation package
for Linux.</li>
</ul>
<p>Vaadin supports Java Servlet API 2.3 and later versions and should work with
any Java application server that conforms to the standard. It supports the following
application servers:</p>
<ul>
<li>Apache Tomcat, version 4.1 or later</li>
<li>BEA WebLogic® Server, version 9.2 or later</li>
<li>IBM WebSphere® Application Server, version 6.1 or later</li>
<li>JBoss Application Server, version 3.2.8 or later</li>
<li>Jetty, version 5 or later</li>
<li>Glassfish, version 2 or later</li>
</ul>
<p>Vaadin supports the following browsers for using the applications made with
it:</p>
<ul>
<li>Mozilla Firefox 3</li>
<li>Internet Explorer releases 6, 7, and 8</li>
<li>Safari 3 and 4</li>
<li>Opera 10</li>
</ul>
<p>The support for browsers follows the support by GWT. The browsers are supported on both
Windows and Mac, if available. Firefox is supported also on Linux (Opera 10a1 works also
on Linux). There may be differences between the
exact versions of the supported browsers that may cause incompatibility with applications
made with Vaadin.</p>
<p>The following browsers are not supported but have been found to
work to a large degree:</p>
<ul>
<li>Safari 2, and 4 beta</li>
<li>Firefox 2</li>
<li>Google Chrome 1.0.x (available only for Windows)</li>
<li>iPhone (firmware 2.2)</li>
<li>Midori (0.1.2)</li>
<li>Epiphany (2.22.3), Galeon, and other Gecko-based browsers. Also WebKit-based Epiphany (2.22.3) works.</li>
<li>Konqueror 4.2 (3.5.x does not work)</li>
<li>Nokia Internet Tablet N800 and N810 (ITOS 2008, Opera-based browser).</li>
</ul>
<p>The reported versions are those that have been tested, though other versions may work
as well.</p>
<p>Nokia E-series phones, such as E90, have been known to work with older versions, but
not with Vaadin 6. Links, Lynx, and other text-based browsers do not
work.</p>
