The term Web Services describes a standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an internet protocol backbone. XML is used to tag the data, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI is used for listing what services are available.
The suggested way for exposing Spring service beans as Web Service is to use Apache CXF, since it helps you build and develop services using frontend programming APIs, like JAX-WS. These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI.
Publishing Web Services with CXF is just a matter of including additional XML into Spring configuration:
<!-- Publishes security web-service -->
<simple:server id="securityWebService"
serviceClass="fr.gfi.admc.service.SecurityService"
serviceBean="#securityService"
address="/SecurityService" />
In other hand if you need to allow your client to reach a deployed WS, you can do it like this:
<!-- Registers security web-service client -->
<simple:client id="securityWebServiceClient"
serviceClass="fr.gfi.admc.service.SecurityService"
address="http://${webServer.host}:${webServer.port}/${webServer.context}/services/SecurityService" />
