Hi Elías

The most likely cause of this is because you do not have the Jaxen jar
in your classpath. You need the Jaxen 1.1.3 (in the JDOM Download zip)
or Jaxen 1.1.4 jar (from the jaxen website).

Check your eclipse build path to make sure you have jaxen in it.

Hello Folks,
I'm using jdom2 in my eclipse project. I want to search with xpath in
XPathFactory factory = XPathFactory.instance();
XPathExpression<Element> exprErrorCode =
factory.compile("/descendant::error_code", Filters.element());
Element error_code = (Element) exprErrorCode.evaluateFirst(_doc);
if(error_code != null){
errorCode = Integer.parseInt(error_code.getText());
XPathExpression<Element> exprErrorDesc =
factory.compile("/descendant::error_description", Filters.element());
Element error_desc = (Element) exprErrorDesc.evaluateFirst(_doc);
if(error_desc != null)
errorDesc = error_desc.getText();
}
