Vaadin has became a popular choice of web applications in many platform and Liferay portal is no exception. There are several business applications built with it and this year's Marketplace app contest Vaadin-based applications took a double-win.
Vaadin Liferay refcard update
The updated Vaadin-Liferay refcard is out. It covers the fundamental stuff you need to know when creating portlets in Vaadin: Setting up the project, deployment models, UI composition, Liferay API integration and much more.
Just try it out
While you can get the refcard directly from Dzone , here are the basic steps needed to start development.
1. Install Liferay 6.2 and Plugin SDK.
These are both available from Liferay website.
2. Install Liferay IDE 2.1 from Eclipse Marketplace
Make sure the liferay-m2e integration gets installed as well, otherwise the Maven project type will not be available in Eclipse wizard.
3. Create new project
Make sure you create and/or choose a Maven profile to your project and the Vaadin framework.
Congratulations! You have the first Vaadin portlet ready. The wizard generates a full project with an example UI. It can be directly packaged and deployed to the Liferay portal either from the context menu Run As -> Run on server… or using the Liferay maven target
To continue building your first portlet, download the Refcard and start experimenting. You’ll notice how easy it is to create nice apps for Liferay portal with Vaadin.
