如果你用的是4.x版本，就放在tomcat_home/common/classes/下

tomcatwebappsROOTWEB-INFclasses

如果有PACKAGE要建一个PACKAGE为名称的文件夹在jsp文件目录下/web-info/classes/你的package文件夹/*.class

如果你没有配置SERVER.XML
那么你的jsp文件要放在webapps/你的jsp文件夹名下
class就放在webapps/你的jsp文件夹名/web-info/classes/你的package文件夹/*.class

重新启动你的服务器！

你的*.class里要有package 你的package才行
放才webapps/你的jsp文件夹名/web-info/classes/你的package文件夹
需要重新启动你的服务器！
