Hi genman, Thanks for your help but the link didn't solve my problem. In fact, I don't use JBoss but Tomcat. I registered in these forums because it was one of the only forums that dealt with that XPath problem. That's very specific, it's pretty hard to find information... I'm not good at XML, but can the problem be related to the fact that the link http://java.sun.com/jaxp/xpath/dom is dead ? Maybe the XPath loader tries to read a XSD or something... Thanks in advance, Mark View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3981550#...
