What is the elatePortal?
We develop a J2EE portal based information system for educational environments. The project started in spring 2005 due to the lack of appropriate systems for managing courses at the Department of Educational Sciences at Leipzig University.
One of the most important features is the eTesting functionality that assesses almost 1000 students per semester at Leipzig University. This is accomplished by an eTesting-Framework that provides support for an extensive testing workflow.
The elatePortal project currently comprises:
- the elatePortal, an enterprise portal based on Apache Jetspeed-2
- the examServer, a lightweight webapp for electronic exams with high security requirements
- the TaskModel, the above mentioned eTesting framework
- the ctEdit, an editor for creating/editing complex question pools for the TaskModel
Proceed to the Introduction or have a look at the Screenshots for a first impression. More comprehensive technical documentation (dealing with the Software Product Line Approach and the elatePortal project as case study) is available as a diploma thesis.
