IntelliJ IDEA lets you create a project using Vaadin Framework that optimizes your Web applicatin development.
Before you start creating your project make sure that Vaadin SDK is downloaded on your computer and Vaadin plugin is enabled.
If you select Java then you might want to specify an application server. For JavaEE the application server is specified automatically.
On the bottom of the page, specify the following settings:
Note that if you selected the Vaadin 6 version, you need to download the Vaadin library. Select Download option and click Configure.
In the dialog that opens, use the default options and click OK.
Select Application Server check box and specify which server you want use for your application. The default application server is Tomcat. Click Next.
IntelliJ IDEA creates a run configuration for your Vaadin application. You can always skip the server configuration at this point and configure it later, after creating your project.
Specify your project information and click Finish.
IntelliJ IDEA creates a project with Web application and all necessary configurations.
