Web services deployment tool using WSDL

Abstract

Following the recent hype of Web Services a number of standards and protocols have emerged. Web Services are not only here to stay but have dominated the Web. They are a new type of Web application and perform functions, which can be anything from simple requests to complex business processes. Once a Web Service is deployed, other applications (and other Web Services) can discover and invoke the deployed service. The Web, however, needs to be augmented with a few other platform services, which maintain the ubiquity and simplicity of the Web, to constitute a more functional platform. The full-function Web Services platform can be thought of as HTTP together with XML, SOAP, WSDL and UDDL Web Services Description Language (WSDL) provides the necessary part of the Web Services picture. It is a universal way to describe Web Services and how they are bound to transport protocols as well as the types they use. WSDL is used to describe what a web service can do, where it resides, and how to invoke it. Now that we can see the whole picture and where WSDL fits into Web Services, we can understand the aim of this thesis. The objective following the design of the Web Services Deployment Tool using WSDL was to enable simplification of deploying a Web Service created in the Java programming language. The tool will be able to create the WSDL service interface together with the WSDL implementation file. The latter is used while publishing the Web Service at a UDDI registry. When a Java class is selected, the user is then able to choose the methods that he wishes to expose as a Web Service. The next step is to simply generate the WSDL file and the SOAP deployment descriptor. The rest of the work is all concealed from the user. By generating these appropriate files, users are able to deploy their already existing Java classes as Web Services with very little extra effort.
