Autonomic computer systems aim to reduce the configuration, operational, and maintenance costs of distributed enterprise applications. This paper provides two contributions to the development of autonomic computing systems using Enterprise Java Beans (EJBs). First, we describe a model-driven development (MDD) tool that formally captures the design of EJB systems, their quality of service (QoS) requirements, and the autonomic properties that will be applied to the EJBs to support the rapid development of autonomic EJB applications. Second, we describe how this MDD tool can generate code to plug EJBs into a Java component framework that provides an autonomic structure to monitor, configure, and execute EJBs and their adaptation strategies at run-time.
