Eliminate JDBC overhead Most J2EE and other types of Java applications interact in some way with information persisted in a database. Interfacing with that database involves several iterations of SQL statements, connection management, transaction lifecycles, result processing, and exception handling. The many parts of this ritualistic dance are common in all contexts; however, this replication doesn't have to exist. This article outlines a flexible framework that remedies the repetition of interacting with a JDBC-compliant database.   |

Build database-powered mobile applications on the Java platform This article explains how to create mobile database applications using the Java 2 Platform, Micro Edition/Mobile Information Device Profile (J2ME/MIDP) and the Java 2 Platform, Enterprise Edition (J2EE). The authors introduce an architecture that uses JavaServer Pages (JSPs) as middleware between a MIDP frontend and a database backend. They also explain specific design decisions and implementation issues, such as persistent storage, network connection, session management, and data communication. Their discussion focuses on the integration between the client and server-side Java applications. |
