Advanced language constructs for developing intra-organizational service architectures

Jini technology delivers a promising environment for building intra-organizational, adaptive service architectures in Java. Currently, however, the level of abstraction is too low, forcing programmers to implement interactions that should have been hidden by the middleware. Moreover, Jini’s limited expressiveness for fine-tuning service selection makes it hard to program complex client-service interactions. In this paper, we present ongoing work on JASA, the Java Advanced Services Architecture. JASA provides middleware abstractions for service computing and provides a Java extension, ServiceJ, with specialized concepts for implementing complex client-service interactions.status: publishe
