Hot Deployment with Dependency Reconstruction

Hot deployment is a typical feature in mainstream application servers. But current application servers treat each module as a standalone application and may fail if a module with dependencies against other ones is partially updated with hot deploying. The reason lies in that those module dependencies are not respected in current application servers. Direct countermeasures that manage dependencies in application servers are actually inefficient or even infeasible. So in this paper, we propose an approach that automatically constructs the module dependencies with class loading mechanism which further helps to reconstruct the modular application respecting the dependencies upon hot deploying. Experiments show that our technology of hot deployment can ensure partial update of the modular applications correctly and efficiently.
