Abstract

SOAP using WSDL(Web Service Definition Language) was proposed for effective integration of distributed objects. But the SOAP message and WSDL document automatically generated from development tool are fully dependent on the development environments. So the dependency of SOAP messages and WSDL documents for objects to the development environment is still a big problem to be solved for the integration of heterogeneous distributed objects. In order to support integration of heterogeneous distributed object, we implemented SOAP Bridge called WBSB(WSDL Based SOAP Bridge). As service request message for a particular service object is translated into appropriate SOAP message for the selected service object by WBSB using WSDL repository, a client can use service object without considering the development environment of the service object.

분산서비스 객체들의 효율적인 연동을 제공하기 위해 제시된 WSDL기반의 SOAP메시지 방식이 제시되었으나, 이 방식에서 사용하는 SOAP메시지와 객체참조문서(WSDL)는 해당 객체의 개발환경에 의존적이므로 서로 다른 개발환경에서 개발된 객체들의 통합을 위해서는 SOAP 메시지와 객체참조문서(WSDL)의 개발환경 의존성을 해결하여야 한다. 본 논문에서는 이종 분산객체 환경에서 객체들의 통합을 지원하기 위해 SOAP Bridge, WBSB (WSDL, Based SOAP Bridge)를 제안, 구현하였다. 서비스 요청 메시지를 WSDL 저장소의 WSDL문서를 참조하여 해당 서비스 객체에 적합한 SOAP 메시지로 변경한 후, 이를 서비스 객체에게 전달하는 기능을 WBSB에서 수행함으로써 사용자는 사용하고자 하는 객체의 개발환경을 고려하지 않고도 해당 서비스를 이용할 수 있다.
