DREAMWEAVER CS3
User Guide
585
These registries use the Universal Description, Discovery and Integration (UDDI) service, an open, e-commerce
service registry that provides a forum for businesses to describe themselves and the goods or services they can
provide to other businesses. A group of companies, called
operators
, maintain the registry. The operators have
pledged to share all public information about registrants among themselves and with users of the service, and to
maintain inter-operability among the multiple peer nodes of the UDDI service network. In addition to public web
services, there are also private UDDI registries available on a subscription basis.
The UDDI specification is based on existing Internet standards, ensuring that it is platform and implementation
neutral.
Web service software components
For a web page to access and use a web service, it must communicate with the service and have a description of the
functionality the service provides, the available methods that it can invoke, and the parameters the service returns.
The Web Service Description Language (WSDL) is an XML-based description of the service. Each web service
provides a WSDL that describes how to bind to the service, the available methods that the web page can invoke, and
the data inputs and outputs. The WSDL can reside in a file, or it can be generated by the web service at run time.
Communication between the web page that requests the service and the web service itself uses the Simple Object
Access Protocol (SOAP). SOAP is an XML-based protocol that lets a web client access and invoke the web service’s
methods and parameters.

About proxy generators
Proxy generators generate a web service
proxy
, a software component that a web page uses to communicate with the
web service publisher. The web service proxy is generated from the Web Service Description Language (WSDL) that
describes the web service. Depending on the server technology you want to develop web service consumers for, you
may need to install and configure a proxy generator that supports that technology.
Dreamweaver installs the Axis proxy generator, which supports JSP web services. Axis is an open-source proxy
generator distributed through the Apache SOAP project. Dreamweaver lets you add obtain and configure proxy
generators that support other vendor’s web service implementations, or new web service technologies.
Note:
Dreamweaver installs by default all the necessary software to use Axis.
To learn more about Axis, see the Apache Axis website at
