Accessing data from servers in mobile devices without using a middleware

Emerging technologies in the mobile world imparts new features to mobile phones rather than calling and texting. They more and more become information systems clients. Advancements 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 Frame work, most information systems for mobile clients require a middle-ware that handles data communication. Middleware is a computer software that connects software components or applications. The software consists of a set of services that allows multiple processes running on one or more machines to interact.The standard way to access databases in Java is JDBC, 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. We used the JSR 177 specification for providing Java ME applications. The increased size of this application makes it more advantageous, even though some limitations prevail. By increasing the size to 64kb we have reduced the limitations to the maximum extent possible.
