This sounds odd to me; isn't WEB-INF/classes *always* treated as if it were an "expanded JAR file"? That is, WEB-INF/classes is directly in the webapp's classpath and resources in there can be loaded by the classloader. If foo.jar (regardless of its location) were on the classpath, anything inside of it can be loaded by the classloader. It doesn't make any sense to me to differentiate between WEB-INF/classes as ... whatever it is usually considered, and using scanAllDirectories="true" to treat is as an "expanded JAR file" because the behavior -- as best as I can tell -- is entirely identical. I've read the documentation for <JarScanner> several times now because of this thread, and it's entirely unclear to me what e=the difference in behavior will be given that documentation plus your comments here. Mark, can you clarify what behavior will actually change when scanAllDirectories="true" is set? >> Then where else should I put an "expanded JAR file", except >> WEB-INF/lib and WEB-INF/classes? > > "should" depends on what you are trying to achieve - something you > haven't yet explained. I get what you're trying to do, here, and its not entirely clear to me under what circumstances an "expanded JAR file" would be useful. It would be nice to understand a proper use-case for this feature, because one presumably exists or the feature would not.
