Description

Any attemp to use axis 2 with XPath expressions from javax.xml.xpath leads to an error like this:

java.lang.ClassCastException: org.apache.axiom.om.impl.dom.DocumentImpl

Sample you can try:
message = MessageFactory.newInstance().createMessage();
soapBody = message.getSOAPBody().addBodyElement(new QName("namespace", "root"));
path = "name(.)";
xp = XPathFactory.newInstance().newXPath().compile(path);
System.out.println("|" + xp.evaluate(soapBody) + "|");

If you think empty body may cause this, fill it: nothing will change. Of use not body, usual SOAPElement: all the same. No need to say, XPath works fine with java's native DOM.
Thank you.
