So I mentioned yesterday that I am attempting to make my first Vaadin app using Eclipse and the Liferay IDE plugin. This post is a word of warning to those trying to do the same thing. The default Liferay Vaadin project is broken; it will not deploy.
To get started, I simply used the Eclipse, “New Liferay Portlet” wizard. So the project skeleton gets build without a hitch. The trouble happens when I attempt to deploy this app in its current default configuration.

A basic, right-out-of-the-box project will not deploy correctly?! Wow, a bang-up job guys!
Fortunately, I didn’t have to spend too much time debugging this, as a coworker of mine is a few months further into his Vaadin training than I am and was able to find a solution rather quickly.
The problem lies in the default configuration of the portlet.xml file. Open the file and change the following line:
<?xml version="1.0"?> <portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" version="2.0"> <portlet> <portlet-name>CreateUser</portlet-name> <display-name>CreateUser</display-name> <portlet-class>com.vaadin.terminal.gwt.server.ApplicationPortlet2</portlet-class> <init-param><name>view-template</name>should be <name>application</name> <value>CreateUser.CreateUserApplication</value> </init-param> ... </portlet> </portlet-app>
Just run the Ant deploy target after this change, and the project should auto-deploy successfully!
