Getting Started with IBM Data Studio for DB2

Appendix D – The Sample Outdoor Company 361
Appendix E – Advanced topics for developing data web
services
This appendix shows you how to take advantage of more capabilities with data web
services, including the following topics:
Consuming web services – using different bindings
Simplifying access for single row results
Handling stored procedure result sets
Using XSL to transform input and output results
Understanding data web services artifacts
Selecting a different SOAP engine framework
E.1 Testing additional web service bindings
You may have clients that require a different binding in order to consume the web service
response and which are not supported for testing in the Web Services Explorer. In this
section, we’ll review a couple of basic items you need to understand for using and testing
these additional bindings, including more detail on the location of the WSDL and the default
message XML schema. Then we’ll explain how to use each of the following bindings:
SOAP over HTTP: This is the binding described in Chapter 10. It is used with WSDLbased
clients like SOAP frameworks, Enterprise SOA environments, and with service
registries such as the WebSphere Service Registry and Repository. We include it here
for completeness.
Web Access: HTTP GET: This is used for quick access from Web 2.0 clients and for
direct access from web browsers.
Web Access: HTTP POST URL-encoded: Used with more “traditional” HTML, such
as for submitting HTML forms.
Web Access: HTTP POST XML: Web 2.0, used by AJAX clients and JavaScript
frameworks using the asynchronous HTTPXMLRequest JavaScript method from a web
browser.
