你贴出的配置和程序没有问题。我调试通过。可能是你别的东西没搞好。

我也在学习struts，有机会多交流啊。^0^

谢谢seerzfm为我查得这么仔细，但改过之后错误依旧。
还有什么方面没有做好呢？

我改成了
<html:form method="POST" action="login.do" onsubmit="return validateLoginForm(this);">
没有任何作用

因为书上写着就是动态，我就照抄的，我改成静态Form了，还是不行,一样的错误.

struts-config.xml
<form-beans>
<form-bean name="loginForm" type="test2.LoginForm" />
</form-beans>

LoginForm.java
package test2;

import org.apache.struts.validator.*;
import org.apache.struts.action.*;
import javax.servlet.http.*;

public class LoginForm extends ValidatorForm {
private String password;
private String userName;
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
/*
public ActionErrors validate(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
return null;
}
*/
public void reset(ActionMapping actionMapping, HttpServletRequest httpServletRequest) {
password = null;
userName = null;
}
}
