Study on Rainfall Information Integration System Based on Java Web Start

To avoid the shortcomings of traditional methods of software deploy, this paper analyzed the principles and advantages of adopting Java Web Start (JavaWS) to deploy the applications of client, put emphasis on transforming applications to jar file, digitally signed the file and created Java Networking Language Protocol (JNLP) file, and the applications were finally accessed by web server. Application of rainfall information integration system based on the WebGIS in Shaanxi province indicates the convenience and security of the system when using JavaWS, which allows users to deploy and use the system offline, and thus it has a good prospect.
