Steps for deploying and testing the Vaadin application in NetBeans are as follows:
Deploying an application in NetBeans couldn't be easier. Just select your welcome project and click on that little green arrow on the toolbar:
Alternatively, you can do the same using the menu Run | Run Project (Vaadin Web Application). Even faster: F6.
NetBeans will prompt you to select a server. You've installed Tomcat, right? Select the Apache Tomcat server and click on OK. Note that you can deploy to any server you have registered in NetBeans, we are using Tomcat just for the purposes of this example.
Once you select the server, you will see a lot of messages on the output console. This is Maven preparing your application. Be patient, this process could take a while, only the first time.
