Debugging the Portlet

A logging mechanism is provided in the PortletContext, accessible from GenericPortlet.getPortletContext() method. The PortletContext.log() method will print a time-stamped message to the web container log and also to the portal log. There are two places to find the logs for the portlet:

WebServer-base/Instance/logs/errors

Includes PortletContext.log() messages

PortalServer-base/portals/Portal-ID/logs/Instance/portal.0.0.log

Includes PortletContext.log() messages. These messages are logged at the log level INFO.
