It is generally not a good idea to share JARs. This should just be done if they require it (i.E. some JDBC drivers). For JCL there is a lot of material about the special issues with wrong positions, i.E. http://wiki.apache.org/jakarta-commons/Commons_Logging_FUD Try to put everything you need under WEB-INF/lib, even if it means to copy the shared JARs into different webapps. Please post the result.
