Consuming SOAP Web Service Sample

A custom state can consume an external SOAP Web service.

The Web service provider in this sample is the United States Consumer Product Safety Commission. The WSDL file (CPSCUpcSvc.wsdl) is embedded with the bundle. Alternately, you can retrieve the WSDL file in real time using the <wsdlUrls> configuration. The JAX-WS Maven plug-in reads the WSDL file and generates all the required artifacts for Web service development, deployment, and invocation.
