java.lang.NoClassDefFoundError: org/dom4j/Document

I have a class called XMLtoXML.java and this is one of it's methods...

import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.Node;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;

public Object[] process(Object data) {

    String templateXML = null;
    Object result[] = null;
    String inputxml = null;
    String templateNumber = null;
    Iterator iterator = null;
    String scenarioConfigUrl = null;
    Node inputNode;
    Node outputNode;
    String subTemplateXML = null;
    String outputXml = null;

    if (delay != null) {

        long time = Long.parseLong(delay);
        try {
            Thread.sleep(time);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
    inputxml = (String) metadata.get(Constants.REQUEST);
    if (inputxml == null) {
        throw new NullRecordException("input data to XMLtoXML class  in   
      metadata map is null");
    }
    Document inputXMLDocument = Dom4jUtils.getDocument(inputxml);

last line of code block uses a dom4j Document.i have dom4j-full.jar in my classpath. if i run this class as standalone(Run as Java application in eclipse) then it works fine. when i add this class as part of web appllication and dom4j-full.jar in my classpath.
i got following exception.

I am also sure that the dom4j jar present on classpath. Anybody have any ideas about issue?

Looks like dom4j-full.jar contains both dom4j and jaxen. From you stacktrace I understand dom4j is in the classpath, and it can find jaxen, but when jaxen looks for dom4j it can't find it. I think the jaxen that has been loaded from dom4j isn't for some reason that one inside the dom4j-full.jar but another one that you have within your application server classpath (and not in your eclipse of course), perhaps loaded from a different classloader. Maybe you have a jaxen.jar in your shared libraries or something like this.
