【摘要】 文章提出了一种基于SOA结构的任务框架来支持空间信息网格(SIG)中的长时间处理服务并将其命名为 thGridJob。thGridJob采用三层结构,为用户和任务开发者提供了不同的编程接口。用户可以通过一系列的Web服务操作来提交和控制任务实例,任务开发者可以使用Java语言、脚本语言和工作流描述语言来开发任务实例。文章还采用Java语言开发设计和实现了一个thGridJob实现以及一个基于Web的用户界面,为SIG用户和任务开发者服务。更多还原

【Abstract】 In this paper, an SOA based job framework named thGridJob is proposed to support long-time SIC processing. It takes a 3-layered architecture and provides two programming interfaces for the users and job developers. Users can submit and control the job instances by a series of web service operations. Developers can develop new jobs by Java language,script language, and workflow language easily. Based on java language, a sample instance with a web-based user interface is designed and implemented. It can provide a powerful and easy-to-use job framework for the users and developers of SIG long-time processing services.更多还原
