用tomcat做一个登陆的动态网页，我是做的3个servlet，不是用jsp做的，第一个是登陆，第二个是用来验证账号密码（使用mysql数据库），没有输出，第3个是欢迎界面。在输入账号密码点击“登录”按钮以后就出现这个错误，完整的报错信息如下：

求各位大神帮忙解决，小弟感激不尽
servlet
------解决方案--------------------
com.org.zh.servlet.LoginProcess这个servlet没有找到，你怎么配置的，怎么访问的，看下
------解决方案--------------------
java.lang.ClassNotFoundException: com.org.zh.servlet.LoginProcess
找不到com.org.zh.servlet.LoginProcess，是你的路径写错了？
------解决方案--------------------
package org.zh.servlet
