Hello!
Both methods belong to the javax.portlet.Portlet interface, which describes the life cycle of a portlet in JSR 168. And both of them are used to handle requests:
processAction()
Called after the user submits changes to a portlet. Intended to process input from a user action.
render()
Called whenever the portlet is redrawn by the desktop.
Therefore in every non trivial portlet component you use both of them.
