Right, I can't tell what file it is complaining about. The file web-facesconfig_1_1.dtd looks fine, and has not changed. The very same file works fine in 4.2.2. If it is the web-facesconfig_1_1.xsd , then line number 25:3 is in the the middle of a comment. I've put DEBUG and TRACE on myt it has not given me any further information. Any idea what file it is complaining about?
