<p>
The <b>getContent()</b> method of a portlet takes a <b>RunData</b> object, which is
passed through from an internal component called <a
href="http://jakarta.apache.org/turbine";>Turbine</a>.
The <b>RunData</b> class is one of the few Turbine classes that you must deal with
often. Turbine is a MVC-2 (Model View Controller) Servlet framework that Jetspeed was
founded upon.
</p>
<p>
Another component coupled to in the Portlet interface is the <a
href="http://jakarta.apache.org/ecs";>Element Construction Set</a> (ECS), an
object-based mark-up generator.
The Jetspeed Portlet interface requires that portlets return ECS elements as their
content. It uses Java objects to construct the elements of the respective mark-up.
Admittedly, this approach is better than hard coding mark-up tags, but it still places
mark-up information into compiled code.
</p>
<p>
Therefore, we generally recommend using a page template mechanism of your choice,
rather than using ECS directly.
The majority of the portlets in Jetspeed are based upon the base class <a
href="http://portals.apache.org/jetspeed-1/portlet_config_Velocity.html";>Velocity
Portlet</a>, a template-based portlet which does not mix Java source with mark-up.
Similarly, you can use the <a
href="http://portals.apache.org/jetspeed-1/portlet_config_JSP.html";>JSP Portlet</a> to
create MVC portlets based upon the Java JSP standard.
</p>
<p>
<b>Note:</b> Starting with version 2.0 of Jetspeed, ECS will be deprecated.
