I have complex validation logic I'd like to process by overriding the validate() method. If errors are found, how are they reported to the JSP? Right now, I can throw exceptions (which works) but leaves a stack trace on the screen instead of indicating which JSP fields have issues.

Nevermind, found addFieldError(fieldName,message) to use. I wonder why I'm having such trouble finding documentation... sigh... Hopefully these posts are helping someone out there.
