java.lang.NoClassDefFoundError: org/jaxen/NamespaceContext

Hello Folks,

I'm using jdom2 in my eclipse project. I want to search with xpath in my
xml file two nodes and I'm using the next code:

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();
}

When I debug the program I get the next error:
