Java - Configuración wsdd para consumir servicio web https

Buenas tardes a todos,

Estoy consumiento un cliente que se conecta a un webservice en una dirección http://
Ahora han cambiado la dirección a una https:// y nos da el siguiente error, que he copiado mas abajo.
Supongo que se debe a que no tenemos bien configurado el archivo wsdd. Alguien podría orientarme como configurar el cliente para poder consumir https?
El entorno es Java, Eclipse y Axis 1-4.

Muchas gracias por vuestra atención,

Carlos.
