There are reasons why the web-app class loader and commons loader are not the same. Only the developer can really decide if jar's can be shared. Take for example log4j. You will find it in many web-apps, but if you try to put it into your common class loader, it will only be initialized by the first web-app. The other web-apps will be able to use it, though. But you will get strange results. Any globally shared ressource, such as static variables or Singletons will get you in trouble. So: Don't do it.
