Abstract

Ideally in the deployment phase, components should be composable, and their composition checked. Current component models fall short of this ideal. Most models do not allow composition in the deployment phase. Moreover, current models use only deployment descriptors as deployment contracts. These descriptors are not ideal contracts. For one thing, they are only for specific containers, rather than arbitrary execution environments. In any case, they are checked only at runtime, not deployment time. In this paper we present an approach to component deployment which not only defines better deployment contracts but also checks them in the deployment phase.
