Cell phones are no longer merely used to make phone calls or to send short or multimedia messages. They more and more become information systems clients. Recent developments in the areas of mobile computing, wireless networks and information systems provide access to data at almost every place and anytime by using this kind of lightweight mobile device. But even though mobile clients support the Java Mobile Edition or the .NET Micro Framework, most information systems for mobile clients require a middle-ware that handles data communication. Java’s JDBC provides a standard way to access databases in Java, but this interface is missing in Java ME. In this paper we present our implementation of an MIDP-based Java ME driver for MySQL similar to JDBC that allows direct communication of MIDP applications to MySQL servers without a middleware.
