Bio: Kim Harding Christensen is one of the founders of Eastfork Object Space (EOS) A/S and is now the Chief Architect at Trifork Technologies, a daughter company of EOS. Kim holds a degree in M.Sc.Computer Science and is also both Sun Certified Java Architect and Sun Certified Java Programmer. Kim has been speaker on a number of lectures and conferences in object oriented system development and participated in a number of international conferences in object oriented system development. Special skils Meta-data & reflection: Meta-data are data, used to describe data. Using meta data and reflection it is possible to build systems that can analyse its own state and, as a result, optimize itself for a given situation. This principle has been used with great succes in the EOS Java 2 Enterprise Edition application server. Active object models: A more easy way of using meta data og reflection is active object models. An active object model is an object model which contains meta information about itself, so that it can chance itself during execution. In enterprise systems active object models can be used to introduce new products and changes in business procedures during runtime (often without changing code). Time-to-marked of new features can be reduced from months to a few days or hours. Object oriented methods: Worked with almost all aspects of object orientation: Object oriented programming (Java, C++, Objective-C, CLOS, Dylan, Smalltalk, BETA, Eiffel, Python, including designing and developing 2 new object oriented programming languages); Analysis & design methods (RUP, OMT, Booch, VMT, Fusion & BON); Object oriented databases; Distributed systems (CORBA, RMI, developed LINDA support to Objective-C) Tutorial, Friday September 14 Enterprise Development J2EE 1.3 Abstract This tutorial gives a practical introduction to J2EE application programming using J2EE v1.3. The first part of the tutorial contain a walk through of the new features in J2EE v1.3: EJB: local invocation, CMP, EJB QL and Message Driven Beans J2EE Connector architecture Web: Servlet filtering and Application Event Listeners In the second part of the tutorial, we will discuss J2EE best practices, approaches to designing, building, and working with J2EE. By using these best practices, you will avoid common pitfalls that others have experienced in the past when building J2EE systems.
