F. Deployment Phase

The objective of this phase is to ensure Web Service is properly deployed to the targeted application server. To validate proper deployment of WS, the server specific WS client is used to conduct the deployment.

 

From WSBP1, the user would specify if the publishing of their web services is required for internal organisation, or extended to their trading partners or external used. This leads to the decision whether to have a private or public service registry to serve their companys needs. If there is a need to publish to a service registry, then activity for gathering additional information for registry publishing is considered for the phase Figure 5 depicts the overview of the extended software methodology lifecycle that has incorporation Web Services best practices in different phases of the lifecycle.

VI. FWSI WEB SERVICES IMPLEMENTATION METHODOLOGY

 

The outcome of this research study is the key contribution to the OASIS FWSI TC Implementation Methodology Sub-Committee (IMSC) for Web Services Implementation Methodology (WSIM) guidelines [13].

 

The purpose of FWSI TC is to facilitate implementation of robust Web Services by defining a practical and extensible methodology consisting of implementation processes and common functional elements that practitioners can adopt to create high quality Web Services systems without re-inventing them for each implementation by defining only the Web Services-specifics activities spans across software development lifecycle.

 

The methodology itself is iterative and incremental. The Web Service would go through all the phases thereby developing and refining the Web Services throughout the project lifecycle per iteration. As compared with the normal structured methodology and agile software methodology, the WSIM has an extra deployment phase after the Testing phase. This phase is specific to Web Services as the developed services need to be deployed and hosted in a targeted application server that provides the reference implementation for Web Services Architecture [14] defined by W3C. Figure 6 outlines the FWSI WSIM Web Services specific activities.
