一部分AdminAction的代码：
public class AdminAction extends AdminForm {
private static AdminDao adminDao = null;

static{
    adminDao=new AdminDao();
}

// 对登录用户的表单验证是否为空
public void validateIndex() {
    if (null == admin_user || admin_user.equals("")) {
        this.addFieldError("admin_user", "| 请您输入用户名");
    }
    if (null == admin_password || admin_password.equals("")) {
        this.addFieldError("admin_password", "| 请您输入密码");
    }
}

// 对登录用户的表单验证
public String index() {
    String query_password = adminDao.getAdminPassword(admin_user);
    if (query_password.equals("")) {
        this.addActionError("| 该用户名不存在");
        return INPUT;
    }
    if (!query_password.equals(admin_password)) {
        this.addActionError("| 您输入的密码有误，请重新输入");
        return INPUT;
    }
    session.put("admin_user", admin_user);
    return SUCCESS;
}

// 对修改管理员密码表单验证是否为空
public void validateUpdatePassword() {

    if (null == admin_password || admin_password.equals("")) {
        this.addFieldError("admin_password", "请输入原密码");
    }
    if (null == admin_repassword1 || admin_repassword1.equals("")) {
        this.addFieldError("admin_repassword1", "请输入新密码");
    }
    if (null == admin_repassword2 || admin_repassword2.equals("")) {
        this.addFieldError("admin_repassword2", "请输入密码确认");
    }
    if (!admin_repassword1.equals(admin_repassword2)) {
        this.addActionError("您输入两次密码不相同，请重新输入！！！");
    }

}

public String updatePassword() {
    String query_password = adminDao.getAdminPassword(admin_user);
    if (!admin_password.equals(query_password)) {
        this.addFieldError("admin_password", "您输入的原密码有误，请重新输入");
    }
    String sql = "update tb_admin set admin_password='" + admin_repassword1
            + "' where admin_user='" + admin_user + "'";
    if (!adminDao.operationAdmin(sql)) {
        this.addActionError("修改密码失败！！！");
        return INPUT;
    } else {
        request.setAttribute("editPassword", "您修改密码成功，请您重新登录！！！");
        return SUCCESS;
    }
}

}
第一次提问，希望大神们多多指教！小弟也会虚心受教。

解决方案

报404状态码，表示请求的资源不可用或请求的页面不存在。你访问的页面为admin_index.jsp，而那个web.xml文件设置的为index.jsp，所以你要把web.xml文件的配置改成admin_index.jsp。

解决方案二：

MyEclipse导入现成项目出现错误

解决方案三：

找不到admin_index.jsp，查查路径正确吗
