Missing Cactus property 應該是你沒有將cactus.properties文件放入：
WEB-INF/classes目錄下參考cactus.properties文件内容：
# Configuration file for Cactus.# Each project using Cactus need to have such a file put in the client side
# CLASSPATH (Meaning the directory containgin this file should be in the client
# side CLASSPATH, not the file itself of course ... :) )# Defines the URLs that will be used by Cactus to call it's redirectors
# (Servlet and JSP). You need to specify in these URLs the webapp context
# that you use for your application. In the example below, the context is
# "test".cactus.contextURL = http://localhost:8020/debug
cactus.servletRedirectorName = ServletRedirector
cactus.enableLogging=true
