How to use Injection from Java EE 6 on Vaadin Portlets

Platform:

• Liferay 6.0.* runnig on GlassFish 3.1.*
• Vaadin 6.6.*

The documentation Creating JEE6 Vaadin Applications, references CDI but does not work with Vaadin Porlets.

In order for this to work, we can adapt the steps described in section "Option 2: Use Context and Dependency Injection (CDI)"

* Remove annotation @SessionScoped() from Vaadin Application
* Use the Vaadin Portlet Class "com.vaadin.terminal.gwt.server.ApplicationPortlet" (instead of com.vaadin.terminal.gwt.server.ApplicationPortlet2). In portlet deployment descriptor (portlet.xml) we will have something like

...

<portlet-class>com.vaadin.terminal.gwt.server.ApplicationPortlet</portlet-class>
<init-param>
<name>application</name>
<value><!-- Replace this with the a valid URI for Created Vaddin Application Servlet --></value>
</init-param>
