Generic java object -> how to generate wsdl

Hi All,

I have the following situation, I have a java class with the following
method:

Document doAction(String action,Document inputDoc){
	... my code ... 
}

The inputDoc and the returned Document does have a format described in a
DTD ( or Scheme). Now I would like to make a SOAP service and a
describing WSDL of this service. Can anyone give me some pointers how to
do this ? 

The only way I came up with was defining the WSDL myself (oh boy) and
create a axis message service which will call the doAction. I hope there
is an easier way ;-)

Kind regards,
Marco Laponder
