Treffer: The Web Service Framework: J2EE

As business workflows on the internet are getting more and more important there is a hype in developing web services. To keep up simplicity of realising web services on the internet there exists numerous standards and technologies, like UDDI, SOAP or WSDL, which also support software engineers in the development process. For a professional web service development, there are general frameworks which include the above mentioned standards and technologies as well as they give approaches for an efficient implementation. The frameworks can be applied regardless to its platform. This paper concentrates on the development of Web Services in J2EE (Java 2 Enterprise Edition) according to the mentioned general Frameworks. J2EE provides a lot of tools and APIs (Application Programming Interfaces) for the implementation of new Web Services as well as upgrading of existing applications. Our goal is to outline the conformity and differences between J2EE and the general frameworks.
