Embedded Web Server and Database Based on Wap

Improve the dynamic interaction between embedded device and mobile phone is an important issue in WAP domain. To address this problem, we make cgi, WMLscript and embedded database collaboratively running to fulfill the requirements of mobile phone. On embedded device, cgi receive the parameters submitted by mobile phone and query the database, it appends the results to the end of wml page and send to mobile phone. On mobile phone side, the WMLscript embedded in wml page will parse the results and displayed on the right place of webpage. We also designed a method that detach cgi with business logic and driver interface. In this way cgi can send parameter to driver application indirectly by exchanging parameters through linux shellt. This enables cgi and driver application to be debugged separately.
