基于Java语言的Web服务的动态发现与调用研究

Web服务是一个崭新的分布式计算模型,它的研究重点是Web服务的新型构架,Web服务的高效执行方式,Web服务与其他成熟技术的有机结合以及Web服务的集成是解决现实应用问题的重要技术。为了充分发挥Web服务的灵活性,用户必须能够动态地发现和调用Web服务。动态发现Web服务的研究目标是服务发现的高效率和自动化。在此使用Java的开放源码包uddi4j,wsdl4j和Apache Axis 2来实现Web服务的动态发现与调用的方法。该方法实现了Web服务与Java技术的有机结合,为更高效率的应用Web服务提供一种思路。

Dynamic Discovery and Invocation of Web Service Based on Java Technology

Web service is a new distributed computing model, and it is also an effective mechanism for the data and service integration on the web. Thus, web service has become a solution to E-business. It is important and necessary to carry out the research on the new architecture of web service in combination with other good techniques and on the integration of services. The Web services must be dynamically discovered and invoked in order to give full play to its flexibility, whose research aim is high efficient and automation. According to the Web Service model framework, the method of dynamic discovery and invoca- tion of Web service using the open source packages uddi4j, wsdl4j, and Apache Axis based on Java technologies is introduced. The method, which puts Web service together with Java technologies can effectively make use of Web Service.
