public interface MVCRenderCommand extends MVCCommand
The render command that to be invoked is determined by two factors:
mvcRenderCommandName of the render URL.
Implementations of this interface must be OSGi components that are registered in the OSGi Registry with the following properties:
javax.portlet.name: The portlet name associated to this render
mvc.command.name: the command name that matches the
mvcRenderCommandName. This name cannot contain
any comma (
MVCPortlet.render(RenderRequest, RenderResponse) searches
the OSGi Registry for the render command that matches both the portlet name
with the property
javax.portlet.name and the parameter value
mvc.command.name with the property
When there are multiple render commands registered for the same portlet name and with the same command name, only the render command with the highest service ranking is invoked.
