/**
 * ----------------------------------------------------------------------------------------------------
 * 本类是一个继承了org.apache.cactus.ServletTestCase的类（它内部间接继承了junit.framework.TestCase）
 * 这样此类便自动拥有了ServletAPI引用，比如要使用HttpSession就可以直接session.setAttribute()
 * ----------------------------------------------------------------------------------------------------
 * 它所依赖的基础jar，如下所示
 * aspectjrt-1.5.3.jar
 * cactus.core.framework.uberjar.javaEE.14-1.8.1.jar
 * cactus.integration.ant-1.8.1.jar
 * cactus.integration.shared.api-1.8.1.jar
 * commons-codec-1.6.jar（需单独下载）
 * commons-discovery-0.4.jar
 * commons-httpclient-3.1.jar
 * commons-logging-1.1.jar
 * geronimo-j2ee-management_1.0_spec-1.1.jar
 * httpunit-1.6.jar
 * Tidy.jar或者nekoHTML.jar和xercesMinimal.jar（本例中的endDoGet()方法要用到）
 * ----------------------------------------------------------------------------------------------------
 * Tidy.jar需要单独下载
 * nekoHTML.jar和xercesMinimal.jar均可从下载到的nekohtml-1.9.18.zip找到
 * nekoHTML的下载地址为http://sourceforge.net/projects/nekohtml/files/
