axisfault getTextContent()

Hi all.

I'm having some difficulties while trying to expose a web service using the yahoo's api.
when I'm running the client, the translation from a location (i.e London) to the woeid number returns this exception:

org.apache.axis2.AxisFault: org.w3c.dom.Node.getTextContent()Ljava/lang/String;

does anyone have an idea what's the problem?

thanks.
