Applet在嵌入式浏览器页面开发中的应用

Application of Applet in the Development of the Page in the Embedded Browser

Applet是Java的一个重要概念。文章以一个移动办公系统的开发为背景,通过对ap-plet和嵌入式浏览器特性的研究和分析,给出了以Applet应用为核心的基于嵌入式浏览器的页面设计方案。并且突破Applet的安全限制,给出了Applet在线情况下访问远程数据库和离线情况下访问本地文件系统的实现方案,以满足该系统对同时支持在线和离线数据操作的要求。

Applet is an important concept in Java. Taking developing of a Mobile Office System as the background, this paper provides the page design method based on embedded browser, which takes the application of applet as the core, after studying the properties of applet and embedded browser. Besides, in order to meet the need of supporting online and offline operation at the same time that the system has, this paper breaks the security limit of applet, provides the methods of accessing local file system when applet is on line and accessing remote database when applet is off line.
