A J2EE application server is composed of multi-tiers: a web frontend, a servlet server, optionally an EJB server and a database. Clusters allow the replication of each tier instance, thus providing an appropriate infrastructure for high availability and scalability of these servers. Clustered J2EE application servers are built from clusters of each tier and provide the J2EE applications with a transparent view of a single server. However, such applications are complex to administrate and often lack deployment and reconfiguration tools. This paper presents JADE, a java-based environment for clustered J2EE applications deployment. JADE is the first attempt of providing a global environment that allows deploying J2EE applications on clusters. Beyond JADE, we aim to define an infrastructure that allows managing as autonomously as possible a wide range of clustered systems, at different levels (from operating system to applications). This paper presents our first experiments using the JADE...
