No offense but this is a really simple Java error on your behalf. Just read the stacktrace:

java.lang.NoClassDefFoundError: org/apache/commons/digester/SetNestedPropertiesRule

 

It clearly says that it cant find a certain file. Just by looking at the missing file package name org/apache/commons/digestor you can conclude that this is a package from the apache foundation. Download the Commons digestor package from the apache website and put that in your classpath.
