Web DBForms Author：Joachim PeerJoachim Peer is an independent J2EE developer. He holds a masters degree in Management Information Systems of Johannes Kepler University, Linz, Austria, with a focus in the fields of software engineering, multimedia application development and knowledge and process management. He is a Sun certified programmer for the Java 2 platform. Many developers find themselves writing similar JSP and servlet code again and again when creating Web-based database applications. The open source project DbForms provides a solution that reduces the amount of coding to an absolute minimum.This article gives an overview of DbForms and its concepts and features, and shows some code examples.Introduction DbForms is a Java-based Rapid Application Development (RAD) environment which enables developers to build Web-based database applications in a very short time and with very little effort. DbForms applications are built in a conceptually very similar manner to RAD database-building tools like Microsoft Access (for Windows-based applications) or Sybase PowerSite (for Web-based applications). The basic principle of these RAD-Tools could be described as placing database-aware components and action elements on templates (forms) which get executed at runtime. DbForms builds on top of Java Servlets 2.2 and Java Server Pages 1.1 technologies by Sun Microsystems. It makes extensive use of the JSP Tag Library extension introduced in the JSP 1.1 specification.The projects homepage is located at and contains a complete user manual, several technical articles, source and binary distributions, online examples, a CVS, mailing lists, and lots of other information related to DbForms.DbForms implements the concepts of the Model-View-Controller (MVC) design pattern.
