A Web service component contained in EAServer can be invoked remotely over both HTTP and HTTPS protocols. The methods are called using the SOAP protocol, and the client calling these methods is said to "consume" the Web service. SOAP provides a platform and language-neutral way to access these services. WSDL is used to describe the Web service so that the client applications know how to interact with it. You can also publish that information to a UDDI registry site on the Web to make your Web service available to other users.
With SOAP, WSDL, and UDDI, collaboration between business partners is easier because interfaces between applications become standardized across platforms.
