Abstract
The paper presents an architectural show case of the web-based e-assessment system JACK. After 12 years of service, the basic architecture of the system has been revised in recent years to overcome several shortcomings of the old architecture. In particular, the original design was too inflexible for further extensions by new grading modules, caused unnecessary restrictions with respect to synchronous and asynchronous grading, and was too generic with respect to exercise specific configuration. The architectural revision achieved to overcome these shortcomings by introducing a message queue as an additional sub-system and moving the border between generic and specific pieces of code. The new architecture is in productive use, includes some legacy components that will be migrated later, shows positive effects for developers and end-users, and allows for further improvements.
