Web Services error

Hi

I'm implementing a simple webService. I've already deployed the server
(*.war file), I've created the stubs and I'm writing now a client
(frankly speaking I'm trying to implement HelloWorld service from
tutorials). When I'm trying to run the client I get this message:

java.rmi.RemoteException: Couldn't create SOAP message factory due to
exception: javax.xml.soap.SOAPException: Unable to create message
factory for SOAP: Provider

Can anybody explain me what I'm doing wrong??
