Prerequisites: This question doesn't relate to some particular application server. The only condition set is that it is about Java application servers (Tomcat, JBoss, WebSphere etc)
Question: I want to deploy application on application server with one feature: I would like to introduce plugin architecture for it. I.e. I want to deploy my MAIN application in a usual way we do in Tomcat, for example, but then I want to be able to dynamically add MODULES to this application using standart application server functionality. After this operation MAIN application should be able to address classes from MODULE, for example it should be able to instantiate classes by class name, read configs from MODULE jar etc.
Is it possible for some application server?
