What is this class

I get this exception trying to deploy a Bean implemented jax-rpc webservice on Websphere.
The only imports my Bean defines that I think are related in anyway are:
import javax.xml.rpc.holders.ByteArrayHolder;
import javax.xml.rpc.holders.StringHolder;
import org.w3c.dom.Node;
import org.w3c.dom.Text;
What is this class? Does anyone know where or what to look at to determine where a dependency for "" is located?
