Subject Re: Problem at geronimo boot

Hi Paolo,

Which DB are you using? I could not get this to work on the derby db that
comes with Geronimo because it doesn't support some keywords (e.g.
AUTO_INCREMENT), but when I used MySQL everything works fine (with or
without the commenting of the filters in the web.xml and on both jetty and
tomcat containers).
