Chapter 1 Introduction

Web Services Toolkit and EAServer architecture

Figure 1-1 demonstrates a client proxy application using an EAServer component for which the Web Services Toolkit has generated WSDL. The option to publish the WSDL with the UDDI host is also presented.

These steps correspond with the numbers in Figure 1-1:

1. Web Services Toolkit generates WSDL and creates a client proxy from the Web Services Toolkit GUI.
2. To publish your Web service to a UDDI registry site, connect to a UDDI registry site from the Web Services Toolkit GUI, and publish the Web service.
3. Your business partner uses the client proxy to invoke your Web service by sending a message to the SOAP servlet.
4. The SOAP servlet invokes the component in EAServer.
5. The SOAP servlet returns the results of the invocation to the client proxy.
