Using Web Elements and External Objects

ws = CreateObject("webservice", "http://localhost/echo.cfc?wsdl");

wsresults = ws.echoString("hello");

writeoutput(wsresults);

Using ColdFusion components to define data types for web services

ColdFusion lets you define components that contain only properties. Once defined, you can use components to define

data types for web services. The following code defines a component in the file address.cfc that contains properties that

represent a street address:

</cfcomponent>

The following code defines a component in the filename.cfc that defines first and last name properties:

</cfcomponent>

You can then use address and name to define data types in a ColdFusion component created to publish a web service,

as the following example shows:

name="echoName" returnType="name" access="remote" output="false">

</cffunction>

name="echoAddress" returnType="address" access="remote" output="false">

</cffunction>

</cfcomponent>

Note: If the component files are not in a directory under your web root, create a web server mapping to the directory that

contains them. You cannot use ColdFusion mappings to access web services.

The WSDL file for the web service contains data definitions for the complex types name and address. Each definition

consists of the elements that define the type as specified in the ColdFusion component file for that type. For example,

the following example shows the definition for name:

</complexType>

You can also specify an array of CFCs in the

attribute, as the following example shows:
