How to set the soapAction property manually in static stub client

[Roy]

I have a wsdl by which i generate my java classes using the WSDL2Java tool. I use  a static stub client to call the service methods. I would like to change the soapAction in the client code. Is this possible and how? I saw a method named setRequestHeader that takes a call object input as a parameter but i get a message that this method is hidden.
