Didactor is an open source E-learning environment. Didactor is the first of a new generation elctronic learning tools, that's focused on the student and can help educational processes become more efficient. It's 100% webbased, works with open standards and incorporates not only SCORM, but also IEEE-Lom and IMS-ld standards. This makes it extremely suitable for use in international perspective. Didactor is used throughout the Dutch educational field (schools, universities etc.) as well as in several companies and also by governmental institutions and the care industry.

Dozer is a powerful, yet simple Java Bean to Java Bean mapper that recursively copies data from one object to another. Typically, these Java Beans will be of different complex types. Dozer supports simple property mapping, complex type mapping, bi-directional mapping, implicit-explicit mapping, as well as recursive mapping. This includes mapping collection attributes that also need mapping at the element level. The mapper is used any time you need to take one type of Java Bean and map it to another type of Java Bean. Most field mapping can be done automatically by Dozer using reflection, but any custom mapping can be predescribed in XML format. Mapping is bi-directional so only one relationship between classes needs defining. If any property names on both objects are the same you do not even need to do any explicit property mapping for these fields. The bean mapper is written in Java and relies heavily on the Jakarta Commons Bean Utils package for Java Bean utility methods. A mapping framework is useful in a layered architecture where you are creating layers of abstraction by encapsulating changes to particular data objects vs. propagating these objects to other layers (i.e. external service data objects, data transfer objects, or internal service data objects). A mapping framework is ideal for using within Assembler type classes that are responsible for mapping from one data object to another. Pick and choose the layers you use mapping carefully. Do not go overboard as there is maintenance and performance costs associated with mapping data objects between layers.

Die rheinjug Düsseldorf bietet hochqualitative Java Fachvorträge kostenlos an. Vorträge finden monatlich an der Heinrich-Heine Universität statt.

Duchess is a world wide network of female Java programmers (and is as such not intended to replace the regular local JUGs).

db4o is the open source object database that enables Java and .NET developers to slash development time and costs and achieve unprecedented levels of performance. The unique design of db4o's native object database engine makes it the ideal choice to be embedded in equipment and devices, in packaged software running on mobile or desktop platforms, or in real-time control systems - in short: in all Java environments, where no database administrator (DBA) is present.
