Major Description
When exceptions occurred during portlet execution, the exceptions are logged in jetspeed log files. The exception logs are found in the container's log files such as localhost_xxx.log in Tomcat 6.
This is because JetspeedContainerServlet just throws exceptions to the container.
I think it would be better to provide a Jetspeed logger component to this kind of common container servlet to give a chance to leave logs in jetspeed log files.
