Web Services mainly provides a number of mechanisms , in order to create a combination of deployment, discovery and invocation of relevant service functions , the next generation of the Internet technology . Its main goal is to build a generic platform-independent , language-independent technology layer on the basis of the existing heterogeneous platforms and applications in a variety of different platforms rely on this technology layer mutual connection and integration . Traditional Web application technology to solve the problem is how to make people to use the services provided by Web applications and Web Services will have to address how to make computer systems to use the Web application services provided . Web Services transaction processing SOAP message security and load balancing is to ensure that the important supporting technology Web Services reliable, safe and efficient . This paper mainly discuss the Web Services protocol stack ( including UDDI, WSDL, SOAP, XML content ) to study the Web Services Coordination framework and safety communications mechanism , load-balancing algorithm to explore the combination of Web Services . The main contribution of this paper is to : 1 . Web Services extend the model of multi - Coordination (WS-MTC architecture ) ; 2 . Combination of characteristics from Web services , research , and Web service path dependencies and combinations coordination strategy ; 3 . Extension of the security of the Web Services the communication protocol -SOAP/XML news package , extended a SOAP-based Web services security model and security specifications with WS-Security . In the extended application framework based on public key system, third-party certification ; 4 . Load-balancing system based on the CBLB load balancing model and improved cooling-delay ~ * algorithm . The article also discusses the improved algorithm to select the combination of services dependent path in Web application . FACE system J2EE/Web Services technology to examine the reasonableness of the model .
