The stacktrace is very probably not related to your problem and the ERROR message is a message sent by the Sun Portlet Bridge (i already open a case on their project so that they don't spit such info on each render phase). Do you have any confirmation that woodstock components work in a JSR-168 environment ? If so, i would suggest you read the woodstock documentation or ask in their forum or mailing list.
