Help with Java Card Technology

Hi there,

Was wondering if anyone has any experience with developing application with Java Card. We want to embark on a new mobile banking solution, and would preferably like to store the application on the mobile Sim Card. From my research this seems possible with Java Card and the help of a cellular network to actually load the application onto the Sim card.

What i wanted to find out is, has anyone got experience in this and if so, could they point me in the right direction to start developing this app. Would also like to find out the server side part of this. As will need to develop a server that handles all the requests that are made by the mobil phone.

Thank you very much in advance
