Mapping XML to Java, Part 1 The SAX API is superior to the DOM API in many aspects of runtime performance. In this article we will explore using SAX to map XML data to Java. Because using SAX is not as intuitive as using DOM, we will also spend some time familiarizing ourselves with coding to SAX. mark for My Articles similar articles

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. mark for My Articles similar articles
