Vaadin on the Web

Overview

Vaadin is a Java framework for building modern web applications that look great, perform well and make you and your users happy. Vaadin is available under the Apache License, Version 2.0 (see the license.html in the Vaadin ZIP or JAR package).

The easiest ways to install Vaadin are:

If using Maven, define it as a dependency or use any of the available archetypes (only vaadin-application is available for Vaadin 7 at the time of this release) to create a new project
If using Eclipse, use the Vaadin Plugin for Eclipse, which automatically downloads the Vaadin libraries

It is also available as a ZIP package downloadable from Vaadin Download page.

Package Contents

Inside the ZIP installation package you will find:

Separate server-side (vaadin-server) and client-side (vaadin-client, vaadin-client-compiler) development libraries
Precompiled widget set (vaadin-client-compiled) for server-side development
Shared library (vaadin-shared) for both server- and client-side libraries
Built-in themes (vaadin-themes) and the theme compiler (vaadin-theme-compiler)
Dependency libraries provided under the lib/ folder

See the README.TXT in the installation package for detailed information about the package contents. Book of Vaadin (for Vaadin 7) gives more detailed instructions.

For server-side development, copy the vaadin-server, vaadin-client-compiled, vaadin-shared, vaadin-theme-compiler, and vaadin-themes from the main folder and the dependencies from the lib folder to the WEB-INF/lib folder of your Vaadin project. (The vaadin-client-compiled 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.)

For pure client-side development, you only need the vaadin-client and vaadin-client-compiler JARs, which should be put to a non-deployed project library folder, such as lib. 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.

Enhancements in Vaadin @version@

The @version@ includes many major and minor enhancements and changes. Below is a list of the most notable changes:

UI replaces Application as the main entry point

Migrating from Vaadin 6

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 UI or UI.LegacyApplication instead of Application. A detailed list of migration changes are given in the Vaadin 7 Migration Guide.

Any custom client-side widgets need to be ported to use the new client-server communication API, or the Vaadin 6 compatibility API.

Vaadin 6 add-ons (ones that contain widgets) do not work in Vaadin 7 - please check the add-ons in Vaadin Directory for Vaadin 7 support.

Vaadin @version@ Dependencies

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.

The Vaadin ZIP installation package includes the dependencies in the lib subfolder. These need to be copied to the WEB-INF/lib folder of the web application that uses Vaadin.

The dependencies are listed in the Licensing description. Some are explicit dependencies packaged and distributed as separate JARs, while some are included inside other libraries.

Bean Validation

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 WEB-INF/lib directory of the web application that uses validation.

Upgrading to Vaadin @version-minor@

Upgrading the Eclipse Plugin

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 http://vaadin.com/eclipse update site. Please see the section about updating the plugin in the Book of Vaadin and the installation instructions at the download site for more details.

You can also use the experimental Vaadin Plugin for Eclipse. Its update site is http://vaadin.com/eclipse/experimental.

General Upgrading Instructions

When upgrading from an earlier Vaadin version, you must:

Recompile your classes using the new Vaadin version. Binary compatibility is only guaranteed for maintenance releases of Vaadin.
Recompile any add-ons you have created using the new Vaadin
Unless using the precompiled widget set, recompile your widget set using the new Vaadin version

Remember also to refresh the project in your IDE to ensure that the new version of everything is in use.

By using the "?debug" URL parameter, you can verify that the version of the servlet, the theme, and the widget set all match.

Eclipse 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).

Maven users should update the Vaadin dependency version in the pom.xml unless it is defined as LATEST . You must also ensure that the GWT dependency uses the correct version and recompile your project and your widget set.

Liferay and other portal users must install the Vaadin libraries in ROOT/WEB-INF/lib/ in the portal (and remove a possibly obsolete older vaadin.jar). Additionally, the contents of the vaadin-client-compiled and vaadin-themes must be extracted to the ROOT/html/VAADIN directory in the Liferay installation. If your portal uses custom widgets, install the latest version of Vaadin Control Panel for Liferay 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.

Notes and Limitations for Google App Engine

The following instructions and limitations apply when you run a Vaadin application under the Google App Engine.

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

For other known problems, see open tickets at developer site dev.vaadin.com.
