In an enterprise application deployment scenario, there are many cases where some libraries are used/referenced by multiple applications. It would indeed be a bad design to include such common libraries with every application deployed on the WebLogic server. Not only does it prevent redundancy of resources on the server, it also consumes valuable space & deployment time - especially when the libraries are huge. WebLogic server offers the shared library concept using which EARs, JARs, EJBs and WARs can be shared across applications in a WebLogic domain.
