Simple Struts Portlet in Liferay 5.2.x

Struts portlets are based on the Struts framework, which is an implementation of the Model-View-Controller (MVC) architecture.

The MVC architecture provides a model for separating the different components and roles of the application logic. This development framework helps you create portlets that are easier to maintain over time.

You have to follow the same procedure and file structures as i mentioned in my last post to create the Struts portlet in Liferay.

I. Development

1.1 portlet-ext.xml

<portlet>
