Java dom4j org/jaxen/NamespaceContext exception

Question

I have downloaded dom4j-1.6.1 and added it to java's build path. I am also familiar with java.lang.NoClassDefFoundError: org/saxpath/SAXPathException but I keep getting an exception.

Enclosed a snippet:

public class Parser {
    public static void parse(final String path) throws Exception {
        final SAXReader reader = new SAXReader();
        final Document document = reader.read(new File(path).toURI().toURL());
        if (document == null) return;
        List list = document.selectNodes("/");
        for (Object o : list)
            System.out.println(o);
    }
}

When I run it, I get the following stack trace

Exception in thread "main" java.lang.NoClassDefFoundError: org/jaxen/NamespaceContext
    at org.dom4j.DocumentFactory.createXPath(DocumentFactory.java:230)

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:356)
    ... 5 more

Any clue what causes the error?

The Exception:

java.lang.ClassNotFoundException: org.jaxen.NamespaceContext

Maybe you forgot to include the jaxen.jar in your Java build's path.

Found out the solution. I had to download and include jaxen in java's build path.
