The GlycomicsPortal is a web based portal intending to serve as a hub for the Glycomics community. It contains relevant Web services, workflow systems, software modules and database systems. The users can register, submit or view existing content. This research enhances the functionality of the web portal by adding the Web service invocation and automatic Web service population features to it. The primary focus of these features is to enable the users to directly invoke and execute all the SOAP and REST Web services registered within the portal without writing a separate client application. This is achieved by introducing a generic SOAP client that handles doc-literal SOAP and REST clients that handles REST Web services. These SOAP and REST clients are integrated within the portal to exploit its functionality.
