Hi All,
I'm deploying a portlet based on the Hepper's HelloWorld example book.
The deployment happens fine but when the portlet is shown, I get the
following error on the browser:
HelloWorld
HelloWorld view | max min nor
Error occurred in portlet!
And in the log files I get:
SEVERE: Error in Portlet
java.lang.NullPointerException
