I have a basic SOAP service endpoint, actually SAP ECC, presenting a service. I have tested the service using SOAPUI 4.5, and it works ok using HTTP Auth, preemptive by the looks of things. I see an outbound "Authorization:Basic BASE64" and the service responds appropriately.
I am now trying to roll this into Java. I thought that I would take a SAAJ approach with:
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
String url = "http://SAPSERVER:8006/sap/bc/srt/rfc/sap/z_lookup_generic_prototype/300/z_user/z_user_binding";
SOAPMessage message = messageFactory.createMessage();
SOAPMessage response = connection.call(message, url);
But I cannot find a way to add the HTTP authentication in. I believe that SAAJ provides the means to control the SOAP message, but how do I add authentication in? Are there any alternatives worth considering?
