LIFERAY TUTORIAL - Creating Vaadin Portlet Using Wizard

INTRODUCTION

This tutorial provides a step-by-step guide on creating Vaadin portlet using wizard. At the time of this writing, there is a bug and manual edit is required to correct this.

STEPS

1. Create new liferay project.
2. Give a name, e.g., Vaadin101.
3. Tick Vaadin portlet type.
4. Click Finish.
5. Check the newly created package in Package Explorer.

2. If the package is directly deployed to the server, the Console Window will display error.
   
3. To correct the error, open the portlet.xml.

   Replace it with “<name>application</name>”
