Based on these measurements, the administrator who sits at a different location which may be far away from the dam location needs to take a decision to open the gates of the dam to avoid floods and such other disasters. The Water Monitoring System application was developed to help the engineer at the dam location to note down the Dam’s water levels through his mobile phone and upload it to a backend server. These readings could then be viewed by the administrator sitting in a different location and take a decision to open the gates of the Dam etc. This application was developed using Java technologies, J2ME, Oracle database and Femto database on the mobile phone. MobilityFramework plugin for Eclipse to aid an application developer in developing Mobile applications Development of an eclipse plugin for developing mobile applications : To develop applications f0or Mobile phones the application developer needs to code a lot of J2ME pages which is cumbersome.
