Answer 1

Caused by: java.lang.ClassNotFoundException: org.apache.commons.digester.Digester

This just tells you that the mentioned class is missing in the runtime classpath. As the package name hints, it's Apache Commons Digester which is available at http://commons.apache.org/digester. If you download the JAR file and drop it in one of the paths covered by the webapp's runtime classpath, such as /WEB-INF/lib, then this problem should disappear.
