Spring Security with Vaadin – basic authentication

Our aim is to do a simple basic authentication on the Vaadin application. I want a login dialog to pop up when we access the URL of the Vaadin application. I have created a simple product catalog application which looks very similar to the address book.

Getting ready

• Set up Vaadin application on Eclipse:
  • Download Vaadin http://vaadin.com/eclipse for Eclipse Indigo.

  For this chapter we will demonstrate Spring Security integration with both the Vaadin versions (Vaadin 6 and Vaadin 7).

  • Create a Vaadin web project in Eclipse with Vaadin 7—this will generate a default application with a click button which we will modify.
  • Run the application on the Tomcat server.
• Create an applicationContext.xml file. It is mandatory to name it as applicationContext, or else we will get error messages in the console.
• Edit the web.xml file with spring listeners.
• Add all the jars in the class-path.
