DEVELOPING COLDFUSION 9 APPLICATIONS
Using Web Elements and External Objects
<!--- Create a structure using CFScript, then call the web service. --->
<cfscript>
stUser = structNew();
stUser.active = TRUE;
stUser.fname = "John";
stUser.lname = "Smith";
stUser.age = 23;
stUser.hiredate = createDate(2002,02,22);
stUser.number = 123.321;
ws = createObject("webservice", "http://somehost/EmployeeInfo.asmx?wsdl");
ws.updateEmployeeInfo(stUser);
</cfscript>
You can use structures for passing input parameters as complex types in many situations. However, to build a structure
to model a complex type, inspect the WSDL file for the web service to determine the layout of the complex type. This
process can take some practice.
Handling return values as complex types
When a web service returns a complex type, you can write that returned value directly to a ColdFusion variable.
The previous section used a complex data type named Employee to define an input parameter to an operation. A
WSDL file can also define a return value using the Employee type, as the following code shows:
<message name="updateEmployeeInfoSoapOut">
<part name="updateEmployeeInfoResult" type="s0:Employee" />
</message>
<operation name="updateEmployeeInfo">
<input message="s0:updateEmployeeInfoSoapIn" />
<output message="s0:updateEmployeeInfoSoapOut" />
</operation>
In this example, the operation updateEmployeeInfo takes a complex type as input and returns a complex type as
output. To handle the input parameter, you create a structure. To handle the returned value, you write it to a
ColdFusion variable, as the following example shows:
