Add a web service to a page
After selecting a web service, generating its proxy, and adding it to the Components panel, you insert it in a page.
The following example shows the Components panel with the web service proxy Helloworld added. The
Helloworld proxy provides one method, sayHello , which prints “Hello World.”
The following example instantiates the HelloWorld web service using ColdFusion.
1 In the Document window, in Code view, drag the sayHello method into the page’s HTML.
Dreamweaver adds the method and dummy parameters to the page.
2 Edit the inserted code with appropriate service instance names, data types, and parameter values, as required by
the web service. The web service provides descriptions of the data types and parameter values.
In the following ColdFusion example, the web service is enclosed by the tags. When developing a web
service in ColdFusion, use to instantiate the web service and invoke its methods.
Web Service
webservice="http://www.mysite.com:8500:8500/helloworld/HelloWorld.cfc?wsdl"
method="sayHello"
returnvariable="aString">
3 To bind a return value to a visual element, switch to Design view and place a visual element on the page that can
accept data binding. Then switch back to Code view and enter the appropriate code to bind the returned value to the
visual element. When creating web services, refer to the technology provider’s documentation for the proper syntax
with which to both instantiate the service and display the returned values to the page.
In this example, the value returned for the variable aString is output using the ColdFusion tag. This
displays the sentence “ The web service says: Hello world! ” to the page.
