Abstract: The automatic information interaction between heterogeneous platforms is the key of building the fourth-party logistics management system based on third-party logistics.The paper proposes a Web service integration platform for it.In the platform，the information resources and software systems of each third-party logistics are treated as Web services，a series of service invoking interfaces is designed by encapsulation of the key words based Web service inquiry，the wsdl4j and castor based WSDL dynamic analysis，the sasj based SOAP dynamic encapsulation，and the jdom based SOAP reply message analyzing，and the third-party logistics Web services are invoked by the fourth-party logistics management system through the service invoking interfaces，which implement the automatic information interaction.

Key words: fourth-party logistics, heterogeneous platform, Web service integration platform, automatic information interaction, Web service invoking

摘要： 实现异构平台间的信息交互及交互自动化是在三方物流基础上构建四方物流管理系统的关键问题。提出了基于Web服务的四方物流集成平台，它将各类三方物流提供商的信息资源和软件系统进行统一封装；并将基于关键字的Web服务查询、基于wsdl4j和castor的WSDL动态分析、基于saaj的SOAP封装和基于jdom的SOAP应答消息解析封装成一个整体，为四方物流管理系统提供一系列的服务调用接口，从而实现了异构平台间的自动信息交互。
