Java language bindings for space based computing: Design and implementation of an API for the space based computing middleware XVSM

Extensible virtual shared memory or abbreviated XVSM is a middleware specification that follows the space based computing paradigm which solves the coordination, transportation and other problems introduced by the collaboration of independent software processes. This thesis discusses the features of XVSM which are then compared to other standards and technologies like JavaSpaces, CORBA and CORSO and finally a Java language binding is introduced. The main focus is directed at the before mentioned language binding and this topic is divided into three parts: The design decisions and goals, a detailed description of the implementation and practical examples and performance evaluations of example code. One of the main challenges of a language binding is the specification which is changing a lot between versions and requires the API to be flexible so that these changes can be incorporated quickly and without breaking any existing software that was written for an older version. Performance is deemed critical for such an API and tests show that runtime and lines of code needed are competitive to implementations for JavaSpaces, CORBA and CORSO.
