Fruitlets - a Kind of Mobile Component
This page gives a short description of a Master's Thesis project developed
during 1996 in the Software Composition
Group of the University of Berne.
The project was carried out by Juerg
Gertsch. The advisor of the thesis was Karl

The tremendous growth of the Internet, especially the popularity of the
World-Wide-Web service led to new situations and problems of software applications.
Thus, we can observe a new application domain of software entities which
appeared in the last few years and which demands for new requirements.
The thesis deals with an approach in the field of mobile code systems
within networking environments. We discuss special stateless mobile software
entities and describe a basic software layer in order to deal with such
stateless mobile components. We use such abstractions in order to attain
adaptability and openness during system's run-time.
The discussion about general problems and requirements leads to a survey
of available technologies in the field. Afterward, we restrict ourselves
to a kind of stateless mobile components and we define properties and demands
of such components.
We introduce the notion "fruitlet" for such special stateless mobile
component and show a prototype of a basic software architecture/environment
in order to host "fruitlets".
The middle part of the thesis deals with a prototype implementation
of our technology. We use the Java programming
language as the implementation language.
The last part of the thesis describes the implementation of a few examples
developed with our technology. These examples show applications which are
dynamically extendable in a restricted way during run-time and startup-time
with stateless mobile components. Furthermore, such applications can also
exchange software parts under some circumstances during run-time.
