Infrastructure for Automatic Dynamic Deployment of J2EE Applications in Distributed Environments CIMS Technical Report: TR2005-867 Anatoly Akkerman, Alexander Totok, and Vijay Karamcheti Department of Computer Science Courant Institute of Mathematical Sciences New York University, New York, NY, USA {akkerman,totok,vijayk}@ Abstract Recent studies showed potential for using component frameworks for building flexible adaptible applications for deploy- ment in distributed environments. However this approach is hindered by the complexity of deployment of component-based applications, which usually involves a great deal of configuration of both the application components and system services they depend on. In this paper we propose an infrastructure for automatic dynamic deployment of J2EE applications, that specifically addresses the problems of (1) inter-component connectivity specification and its effects on component configu- ration and deployment; and (2) application component dependencies on application server services, their configuration and deployment. The proposed infrastructure provides simple yet expressive abstractions for potential application adaptation through dynamic deployment and undeployment of components. We implement the infrastructure as a part of the JBoss J2EE application server and test it on several sample J2EE applications. 1 Introduction In recent years, we have seen a significant growth in component-based enterprise application development. These applications are typically deployed on compa
