Re: how to add child to SOAPBodyElement

[tony . q . weddle]

I've never used these particular method signatures but you will have to create an array of body elements to return. You can't use the input elements (from the request) to get hold of the response SOAP envelope. You need to create a new array of reponse elements, to return, there is no point in returning the input elements. Axis will put those elements into a SOAP message that it creates to send back to the client.
