摘　　要：随着网格技术发展,尤其是WSRF提出后,网格服务构建及其管理逐渐成为网格技术的核心研究内容。受限于工具,传统网格服务构建较复杂,需手工编写业务逻辑代码及相应WSDL文档,致使网格服务构建门槛较高、功能变化难度较大。鉴于GDT工具构建网格服务的便捷性,本文详细阐述了Windows环境下基于GT4.2.1、Eclipse3.7、GDT的网格服务构建流程及调用过程,并以整数累加(Math)服务为例完整说明了基于GDT的网格服务构建过程。With the development of grid technology, especially after the propose of WSRF, the building and management of grid service gradually become the core research issues of grid technology. Limited by the tools, the traditional grid service building is comparatively complicated. Developers need to write the grid service＇s business logic codes and the corresponding WSDL documents manually, which make it difficult to build grid service, and resuh in the functional changes more difficult. In view of the convenience of building grid service by GDT, this article describes the process of building and invoking grid service based on GT4.2.1, Eclipse3.7 and GDT in the Windows environment, and takes the integer accumulation （Math） service as an instance to reveal the building process of grid service based on GDT in detail.
