Given the discussion in this article, I recommend that, when designing an application that uses JSPs, servlets, and EJBs together, any class that is shared by more than one application be placed into a common.jar file that is specified in the manifest Class-Path: entry of all applications that make use of it. Additionally, add any other support libraries to the appropriate manifest Class-Path: and place any Web application-specific libraries in the WEB-INF\lib. Following this approach, you should have smooth sailing from here on out!

Where do I place that common.jar file IN EJB.jar or WebApp.war or EAR root?
