DigesterFactory logs warnings if certain resourecs are not available on the classpath. If the JSP jar is not present this automatically results in 6 warnings about TDL/XSD resources which are clearly not going to be needed. It would be nice to be able to switch that off. Even better if it could be done in Tomcat 7 as well.
This has already been fixed in trunk as part of bug 55166. There are no plans to back-port this to 7 as it requires dupliating resources across the JARs (since some users may be depending on the current locations). *** This bug has been marked as a duplicate of bug 55166 ***
