Today even small mobile devices access the internet. Therewith, mobility issues have become an important technical and economic topic - not only in new but in proven and successful web applications as well. The main problem derives from a growing development of heterogeneity in hardware and software of mobile devices. To overcome this problem, this paper presents a framework to develop Web Applications for Mobile Devices. This framework issues important points when developing web application that also focuses on mobile users. This includes completely new developments, as well as development that issue an upgrade of existing web applications to mobile devices.
