Implementation of runtime pluginable system in JBoss application server

This paper describes an implementation of a system which provides plugin functionalities in JBoss application server. It uses JNDI namespace for detection of new modules, which is updated after JBoss deployment scanner finishes scanning of the deployment folder. Our system provides detection of certain types of modules (plugins) in runtime. These modules are, in our case, classes that implement different interfaces. Clients (other modules) that want to use certain types of plugins, register themselves at Component Manager, which notifies them when modules of such types are detected. Detection of modules that are currently deployed on the application server is achieved using JNDI namespace. Modules registered in the namespace are checked for classes that implement certain interfaces — plugin types.
