Yes, that is the line that 'cause the error' but the real error is that your parser does not understand it. So maybe you are not aware of some other parser but afaik, if a specific xml parser is loaded via jaxp, that will be used by other applications as well. The Aefred parser is not a default parser of my jdk's (openjdk 1.6 and the sun 1.6 jdk) So it might be part of some plug-in or library or whatever. But.... this is only based on my experience with this error in previous projects View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4258757#...
