Extending a Java']Java based framework for scientific software-components

A prototypical framework, which was used for building software components for symbolic computation, is extended as follows. First, we demonstrate that the server components can be accessed from other frameworks for collaborative scientific computing, too. Specifically, we incorporate access from the PROGRESS system. Second, we discuss several design issues that arise when encapsulating existing systems as services into the framework. Many of these issues are of a general nature but become relevant in our effort to incorporate the invariant package of MAS and the quantifier elimination package qepcad into our framework.
