Java.lang.reflect.UndeclaredThrowableException on deployment

Question

I am trying to deploy very simple web app and on start up I got this exception java.lang.reflect.UndeclaredThrowableException.
My web.xml has <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application
2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"> as header.If I change this to
point to version 2.2 everything is OK.I am running WLS6.1sp2.
Can somene shed some light on this for me?
Thanks

Note that WebLogic 6.1 doesn't implement final version of Servlet 2.3 spec,
          and javax.servlet.Filter shipped with WebLogic is different from one in the
          final spec. Try to recompile your filter with weblogic.jar in the classpath
          and add missing methods.
