Dear All: I have a question about how to manage this problem, maybe you can help me, The problem is I have a war created by a Third Party which load a class using Class.forName() and I want to add a jar without manipulate the bundle WAR (WEB-INF/lib), I know that is possible to deploy a jar in JBoss AS 7 but I am not sure if there are a smart way to add a jar without manipulate that jar. It should be possible only add jboss-deployment-structure, be aware that my own jar could change through the time because we can add more classes or change some functionality. Thanks for you recommendation Fred
