<p>WSDL for client access
A WSDL service description provides all the information that is required to use a web
service. The T320 version of Eclipse incorporates the Web Tools Platform (WTP),
which provides support for generating a client based on the information inside a
WSDL.
OU demo services
</p><p>At the OU there is a small set of toy web services. These can be accessed using a
client in the same way as you tested the 'Hello' web service using Eclipse. In fact, one
of the web services hosted is a copy of the 'Hello' service.</p>
