[jdom-interest] JDOM XPath error...help needed.

Mon Mar 17 20:00:00 PST 2003

Not sure which direction, but this is a mismatch between Jaxen and
JDOM.

The jaxen you're using expects Text::getValue() in the JDOM package.

That method appears to be missing from the JDOM you're using.

So, I'd start flipping around different versions of jaxen and jdom
jars, and sure you only have 1 of each in  your effective classpath.
