Abstract

Web services refer to a paradigm consisting on communication between applications interfaces. They are the main key to communicate between different environments, such as Cloud Computing based architectures, and constrained environment. SOAP web services are more used then REST web services in education and industrial environment; contrariwise, Media data in web applications used REST web services. The main aim of this paper is to make alive and complete a previously proposed middleware SaaS solution, to enable unattached WSDL and WADL file translation. The Maas architecture is strengthen by developing Converter component and mapping rules component used in our previous work.

Highlights

  • In our previous research papers [1,14,15] we have proposed a Middleware as a Service (MaaS) based architecture to enable interoperability in heterogeneous client and provider environment

  • We explain in detail some part of our architecture such as WSDL/WADL converter that can support Web Services Description Language (WSDL) and Web Application Description Language (WADL) files illustrated as WSDL and WADL objects used by the Converter

  • The handling of XML document is accomplished by using objects generated from a Document Type Definition (DTD) for Java Architecture for XML Binding (JAXB) 1.0 and an XML schema of the document to be processed for JAXB 2.0

Summary

Introduction

In our previous research papers [1,14,15] we have proposed a Middleware as a Service (MaaS) based architecture to enable interoperability in heterogeneous client and provider environment. We have set up this architecture as a set of components to enable our solution to be more flexible to maintain, update and to be a general architecture that provides solutions to interoperability problems in different levels. This architecture respects the concept of modularity that separates tasks of the components.
