building java SOAP client to access comscore api

I am looking for a simple java client which allows me to access simple SOAP api's. they expose their SOAP webservice as a HTTPS service with ‘Basic Auth’ protocol for authentic开发者_开发问答ation.

Can someone tell me how can I test my changes.

If they provide WSDL files for their SOAP interfaces, you can generate Java stub classes out of that. SOAP implementations like Apache Axis and CXF provide a wsdl2java tool that helps you with this. Then you can use the stub classes to talk to the remote SOAP services. Axis and CXF documentation has more information.
