预备
jakarta-cactus-1.8.0
junit-3.8.2.jar
配置 1、从 http://jakarta.apache.org/cactus/ 下载jakarta-cactus-1.8.0-bin.zip，解压后将lib目录下面的所有*.jar文件复制到应用的WEB-INF/lib目录下。jar文件清单如下：
aspectjrt-1.5.3.jar
cactus.core.framework.uberjar.javaEE.14-1.8.0.jar
cactus.integration.ant-1.8.0.jar
cactus.integration.shared.api-1.8.0.jar
cargo-ant-0.9.jar
cargo-core-uberjar-0.9.jar
commons-httpclient-3.1.jar
commons-logging-1.1.jar
httpunit-1.6.jar
jasper-compiler-5.5.9.jar
jasper-runtime-5.5.9.jar
junit-3.8.2.jar
list.txt
nekohtml-1.9.6.jar
org.mortbay.jetty-5.1.9.jar
servlet-api-2.4.jar
2、在WEB-INF/classes 目录下建立cactus.properties 文件，文件内容示例如下：1

# 可选属性。默认为 FilterRedirector
#cactus.filterRedirectorName=FilterRedirector
# 可选属性。默认为 ServletRedirector
#cactus.servletRedirectorName = ServletRedirector
# 可选属性。默认为 JspRedirector
#cactus.jspRedirectorName = JspRedirector
# 可选属性。不过，在测试Filter时是必须的，否则将无法成功执行测试。
cactus.jetty.resourceDir=D:/Project/test/WebRoot

故障处理 故障1 运行Filter的集成测试时出现如下异常信息：
org.apache.cactus.util.ChainedRuntimeException: Failed to get the test results at [http://localhost:8080/test/FilterRedirector]
解决方法 ：在cactus.properties 中加入 cactus.jetty.resourceDir 的配置。
故障2：连接被拒绝 1）有可能是firewall阻止了端口的访问；
故障3 - web.xml解析失败 原有web.xml的配置如下：1

采用Cactus + Jetty5 集成测试时会失败，原因是Jetty5不支持这样的配置，改用如下方式解决：1
