Summary: Jaxen-based Applications no longer working wth JBoss >=3.2.4
Initial Comment:
Hello,
I have a lot of applications based on XPath, which uses
Jaxen for XPath processing. Through JBoss deliveres
within JBoss 3.2.4 and 4.0 JDom as library, also Jaxen
will be delivered in an incompatible version to the
Jaxen-Final. Also the delivered Jaxen version is not
complete, so generic XPath is no longer working because
of the classloader as well - Im currently using the
<lib> element in the applications.xml of my ear.
Here is a short snipped which will no longer work with
this versions:
import org.jaxen.BaseXPath;
import org.jaxen.dom.DOMXPath;
public static Iterator findNodes(Node node, String
xpathquery) {
Iterator it = null;
try {
BaseXPath expression = new DOMXPath(xpathquery);
it = expression.selectNodes(node).iterator();
} catch(Exception exe) { }
if(it==null) {
it = new Vector().iterator();
}
return it;
}

Added solution to original topic:
http://jboss.org/index.html?module=bb&op=viewtopic&t=51255
Basic jist is, current dom4j-1.5-rc1 does not seem to expose this conflict.
It may not be a 100% proper solution, but it does allow someone to move
from < 3.2.4 to 3.2.4 + without getting the nosuchmethod exceptions

Here is a simple EAR file (source packaged inside) that
shows the conflict with the versions of Jaxen in jdom and
jboss 3.2.4+
(I don't see an attach check box, I'm just hoping that it
will show up after I submit this)

3.2.4 does not ship with jdom, it ships with dom4j, which is
what includes jaxen. You will have to configure your
application to override the jboss classes using scoped class
loading as described here:
http://www.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration
If this does not work create an ear which demonstrates the
problem.
