没见过楼主这样写法的，所以不知道是否可以成功，估计
javax.servlet.ServletException: No getter method for property teacher.uname of bean org.apache.struts.taglib.html.BEAN是指没在form类中找到getTeacher.uname方法，struts并不会先找到getTeacher方法，然后获得teacher实例，再获得user吧．

在不了 我在action 中写forward
必须用 success 或 failure
<action path="/add1" type="app.TeacherAction" name="TeacherForm" scope="request" input="input.jsp">
<forward name="success" path="/success.jsp"></forward>
</action>
我要换成别的 怎么找不到

问个其他的问题 一个网站 并发 量 是由什么因素决定的,例如 多个用户同时对数据库操作就会很慢, 主要原因是不是web 服务器决定的??可以给些意见吗

怎么能对不上呢? 我的 input.jsp中的 action="add1.do"
在struts-config.xml
中配置为
<action path="/add1" type="app.TeacherAction" name="TeacherForm" scope="request" input="input.jsp">
add1.do 和 path="/add1" 应该是对应的 这么写难道不对吗?
如果 我不用Teacher.java 而 用TeacherForm.java 直接提取表单中数据就可以

javax.servlet.ServletException: No getter method for property Teacher.user of bean org.apache.struts.taglib.html.BEAN
看错误，首先他没找到你配置的TeacherForm，应该是add1.do 和你配置的/add1 对不上。
如果找到了TeacherForm，他会报
javax.servlet.ServletException: No getter method for property Teacher.user of bean app.TeacherForm
其次才是找不到属性Teacher.user 的getter方法。属性名仅为user ，前面的Teacher.不用

<html:form action="add1.do">
换成 <html:form action="/add1">
然后 Teacher.name 把前面的Teacher. 去掉
