如果想在把一个servlet程序部署在tomcat之上测试它能否运行，做一个初步的测试。而不想花时间为这个servlet来构建一个完整的web应用。 通过执行Tomcat 的Shell 命令来关闭它<tomcat-installation-directory>/bin/shutdown。
复制这个servlet文件到tomcat的缺省web应用中，或者用Ant工具的build.xml文件来移动这个文件临时地进入到Tomcat的缺省web应用中。
有时候当我们设计出一个servlet时，会渴望看看它是否能正常运行。你能够测试它通过复制它到Tomcat的缺省web应用下，除非这个servlet还得运行还需依靠其他的servlet或其他的类组件。这个取胜的应用位于<Tomcat-installation-directory>/webapps/ROOT.
如果有一个完全合法的Servlet类叫做mydev.CookieServlet,那么下面将有一个完整的步骤手动将这个单独的Servlet部署到Tomcat中。
创建一个mydev目录把它放到 <Tomcat-installation-directory>/webapps/ROOT/WEB-INF/classes目录下 复制CookieServlet class文件到<Tomcat-installation-directory>/webapps/ROOT/WEB-INF/classes/ jspservletcookbook目录下 启动Tomcat 输入http://localhost:8080/servlet/jspservletcookbook.CookieServlet.
这个手动方法比较麻烦并且很慢有没有比这个更好的部署方法呢？答案是肯定的；
我们将用Jakarta Ant来代替手动部署的流程。假定我们已经安装配置好了Ant开源工具
创建一个方便的目录在下面放入build文件并创建一个global.properties文件
在widows命令行中转到这个目录下 敲入ant命令。

tomcat.webapps=k:/jakarta-tomcat- 4.1.12 /webapps/ROOT
tomcat.dir=k:/jakarta-tomcat- 4.1.12
url=http://localhost:8080/manager
compiled.servlet=CookieServlet
username=tomcat
password=tomcat
用一个属性文件global.properties来加载这些在这个property文件中定义好的属性。如：
${tomcat.dir}
global.properties 文件
