29、方网站上下载一个，下最新版本7. x版本，地址 http:/tomcat, apache, org/,下载windows版的,下载后exe文件一溜安装，安装内容部 分的选项全选，其他全部默认配置，中间有个admin密码的地方，输入你自己设定的密码即 可。安装后启动，如果启动不了，请检查安装的jdk版本，也换成最新的重新安装。安装完 了后，服务启动tomcat,浏览器输入，http:/localhost:8080/, ok,页面出来正常表示。3,下载tomcat对eclipse的插件。下载土也土止：http:/www. eclipsetotale. com/tomcatPlugin. html

30、这个页面还有，安装说明的，英语好的可以自己看看。下载的时候针对你安装的eclipse 的版本下载，下载后解压，解压后的文件放到eclipse的plugins目录中，如果eclipse 是3. 7版本的放到dropins文件夹。配置完毕，应用按钮按下，关闭，然后先从window的服务中停止tomcat的服 务，回到eclipse的页面，点那三个图标，ok 了吧，下面的console的窗口有反映 了吧，然后打开浏览器，http:localhost:8080/ok 了, tomcat 启动了if(con.getGrouplD().equals(grouplD)groupCon.add(con);)r
