Improvement to the Smart Data Server with SOAP

As a distributed computing middleware, the Smart Data Server (SDS) provides a general framework for easy-to-build environment-independent modules with distributed functionality and a secure mechanism for invocation. But there are still some problems in the widespread cooperation with other distributed computing system and client terminal. Nevertheless, SOAP, as a new promising simple object access protocol, provides a mechanism based on XML for the structured message exchanging in the distributed environment. Here we take SOAP as the protocol for message transport between the remote client and the Smart Data Server instead of the its own “Information Package Transfer Protocol” (IPTP), and the SDS gains some new advantages: it can cooperate with other distributed computing solutions, such as CORBA, DCOM, RMI and so on; the SDS can be applied more widely for the SOAP message transferred through HTTP, a wide and most common used protocol in the Internet.
