1.开发 Web Services，编写cfcdemo.cfc组件，代码如下：
<cfcomponent style ="document"
namespace = "http://www.mycompany.com/"
???serviceportname = "RestrictedEmpInfo"
???porttypename = "RestrictedEmpInfo"
???bindingname = "myns:RestrictedEmpInfo"
???displayname = "RestrictedEmpInfo"
???hint = "RestrictedEmpInfo">
???????? <cffunction name = "getEname" access = "remote" returntype="xml" output="no" >
??????????????? <cfargument name = "dname" type = "string" required = "false">
??????????????? <cfargument name = "loc" type = "string" required = "false">
??????????????? <cfquery name = "dt" datasource = "scott">
?????????????????????? select * from dept where
?????????????????????? <cfif arguments.dname neq "">
?????????????????????? dname = #arguments.dname#
?????????????????????? </cfif>
??????????????? </cfquery>
??????????????? <cfxml variable="Books">
??????????????????? <XML>
??????????????????????? <cfoutput query="rs">
??????????????????????????? <book>
??????????????????????????????? <bname>#deptno#</bname>
??????????????????????????????? <isbn>#dname#</isbn>
??????????????????????????????? <writer>#loc#</writer>
??????????????????????????? </book>
??????????????????????? </cfoutput>
??????????????????? </XML>
??????????????? </cfxml> ????????????????
??????????????? <cfreturn Books>
???????? </cffunction>
</cfcomponent>
<!---
ColdFusion开发 Web Services,只需要在ColdFusion组件（.cfc文件）中,
把需要作为 Web Services 的method的access类型定义为remote就可以了（access="remote"）。
--->
2.测试一下，访问这个cfc组件，注意URL路径后边要加上 ?wsdl 。
eg:http://localhost/mysys/cfcdemo.cfc?wsdl
显示效果如下：
3.开发测试页面，编写webservice.cfm程序调用①开发的 Web service ，代码如下：
<cfset sWebServiceUrl = "http://localhost/cfcdemo.cfc?wsdl">
??? <cfinvoke webservice="#sWebServiceUrl#"
component = "cfcdemo"
method = "getdept"
returnVariable = "dept">
??????? <cfinvokeargument name = "dname" value="10"/>
<!--- 访问参数，与参数值，对应.cfc中的 cfargument --->
??????? <cfinvokeargument name = "loc" value=""/>
??? </cfinvoke>
??? <cfdump var="#dept#">
4.说明：调用 Web Service 时，webservice.cfm部分和cfcdemo.cfc?wsdl对应如下：
<cffunction></cffunction>
<!--- cfc组件中的方法，在cfcomponent中可以有多个 --->
method -- 对应cfc组件中的方法，<cffunction>标签内name属性的值
timeout -- 设置请求超时秒数
returnVariable -- 自定义的变量，里边存放的是 Web Service 返回的值
<!---传递参数--->
<cfinvokeargument name="empno" value="7788"/> --
<!---接收参数--->
<cfargument name="empno" type="string" required="true">
<cfoutput>#dept#</cfoutput> -- 输出 Web Service
<!--- 注意返回类型一定要与 returntype 对应--->
