Abstract

topics on accessibility, interoperability, durability, and reusability of component level. The Web Service Oriented Framework not only with the abilities above, but provide the solution to fits the requirements of LMS as stated previously. It also well hides the complexity of implementation from programmer to speed up the design process, and to facilitate system maintenance. Therefore, applies the Web Service Technologies to SCORM makes the implementation, maintenance of LMS easier. Another benefit of using Web Service Technologies to implement LMS is the system can be customized based on different requirement. Since most components not located at local area, but from remote host, the main job of developer is to search and bind the appropriate service in internet without coding them directly. In this paper, we sketch the structure of SCORM compatible LMS as web service components, and design a search service for automated discovery of appropriated service from registered distributed learning services. Based on the Searching Service, we construct a web service mapping remote service to the local request. We also apply web service relative technologies like SOAP, UDDI, WSDL and WSFL to our framework. The technologies being used in this paper include servlet, JSP, JAM, JAX/RPC, and MVC concept. The most popular XML APIs are the Java XML APIs, which also used as run-time environment to implement our prototype. Figure 1 shows the highly generalized model of LMS. The remainder of this paper is organized as follows. Section 2 describes the basic technologies of Web Service and LMS components. Section 3 presents the web-service oriented framework for LMS. Section 4 discusses the advantages and disadvantages of the framework and draws a conclusion. 2. Background
