基于Java Web Start的铁路调度查询系统研究

论述了铁路局运输调度查询系统的重要性,介绍了Java Web Start技术的原理及优点,并以铁路局实时运行图查询系统为例说明了其具体实现方法,详细说明了该技术对于环境的要求,并给出了设置Web站点的具体步骤.同时,重点论述了JNLP文件的编写方法和.jar文件的签名方法.使用Java Web Start技术可以方便地实现实时列车运行图的查询,可以为铁路局相关运输生产管理部门提供准确、及时完备的列车运行信息,为合理组织各项运输作业提供科学的依据.

Study of Railway Bureau Dispatch Query System Based on Java Web Start

In this paper, the significance of railway bureau dispatch system query system is expounded. The principles and advantages of Java Web Start technology are introduced. And the railway bureau real-time train diagram query system is employed as the example to elaborate the realization method. Moreover, the environment requirements of this technology are studied and the concrete steps of deploying the Web site are studied. Meanwhile, the methods of compiling JNLP file and signature of jar file are discussed in detail. Thus, the real-time train diagram query system is developed expediently. By using this system, the self-contained train running information is provided exactly to the related transportation management departments. And the reasonable basics are provided to the organization of railway bureau transportation activities.
