—Because of reusability advantage many business applications are developed using service oriented architecture (SOA). Using Web services we can integrate different modules of business logic. Main components of SOA based applications are service provider, service consumer and service repository. Communication between these components is achieeved by exchanging SOAP messages, which are XML documents. XML to Java mapping is difficult process. This process is time consuming. WSDL2WS is an application framework for developing Java web services. It is prototype framework and uses WSDL based approach for designing Java Web Services. This is called as contract-first Web service development and fo this approach we need to think in terms of XML. It is the XML that is sent across the wire, and we need to focus on that. The fact that Java is used to implement the Web service is an implementation detail. Using XML and WSDL we can develop a Java web services. Our application framework attemps to remove some drawbacks in developing web services using Java EE approaches. Web services interfaces, in the form of WSDL files, can be published to a business registry; these interfaces can then be dynamically looked up by clients. We compared performance of our framework with Apache Axis 1.0 and 1.2. for some Web services.
