在基于Web的远程故障诊断系统,需要在不同页面利用不同的分析工具对同一组数据进行分析。为了避免页面反复从数据库读取同样的数据,有必要在不同页面之间共享数据和通信。然而在用Java Applet编写界面时发现,Java本身的安全机制限制了这种通信的进行。本文找到了一种页面数据交换途径,使用户在客户端不用通过服务器中转就能够实现不同页面之间的数据交换,免去了网络通讯带来的延迟,提高了远程诊断系统实时分析的能力。
In a Web-based remote troubleshooting system, different analysis tools need to be used on different pages to analyze the same set of data. In order to avoid page repeatedly from the database to read the same data, it is necessary to share data and communication between different pages. However, when using Java Applet to write the interface, it was discovered that Java’s own security mechanism limited the communication. This paper has found a page data exchange approach that enables users to exchange data between different pages without having to go through the server in the client, eliminating the delay caused by network communications and improving the ability of real-time analysis of remote diagnostic systems.
