I would like to use the action to send SoapClient (Wise) to access an external webservice. However, to connect to the web service is used with SSL Mutual, where I have to use a certificate. What would be the best way to work with SoapClient and SSL?
Well, regarding SSL and webservices please take a look at http://jbossws.jboss.org/mediawiki/index.php?title=Secure_transport, in particular where it talks about setting system properties on client side. We are going to provide a mean of configuring that through wise, in the mean time you can try manually setting them in the Wise's client (perhaps you might need to store the wsdl contract locally).
