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

static{
    adminDao=new AdminDao();
}

// 對登錄用戶的表單驗證是否為空
public void validateIndex() {   
    if (null == admin_user || admin_user.equals("")) {
        this.addFieldError("admin_user", "| 請您輸入用戶名");
    }
    if (null == admin_password || admin_password.equals("")) {
        this.addFieldError("admin_password", "| 請您輸入密碼");
    }
}

// 對登錄用戶的表單驗證
public String index() { 
    String query_password = adminDao.getAdminPassword(admin_user);
    if (query_password.equals("")) {
        this.addActionError("| 該用戶名不存在");
        return INPUT;
    }
    if (!query_password.equals(admin_password)) {
        this.addActionError("| 您輸入的密碼有誤，請重新輸入");
        return INPUT;
    }
    session.put("admin_user", admin_user);
    return SUCCESS;
}

// 對修改管理員密碼表單驗證是否為空
public void validateUpdatePassword() {

    if (null == admin_password || admin_password.equals("")) {
        this.addFieldError("admin_password", "請輸入原密碼");
    }
    if (null == admin_repassword1 || admin_repassword1.equals("")) {
        this.addFieldError("admin_repassword1", "請輸入新密碼");
    }
    if (null == admin_repassword2 || admin_repassword2.equals("")) {
        this.addFieldError("admin_repassword2", "請輸入密碼確認");
    }
    if (!admin_repassword1.equals(admin_repassword2)) {
        this.addActionError("您輸入兩次密碼不相同，請重新輸入！！！");
    }

}

public String updatePassword() {        
    String query_password = adminDao.getAdminPassword(admin_user);
    if (!admin_password.equals(query_password)) {
        this.addFieldError("admin_password", "您輸入的原密碼有誤，請重新輸入");
    }
    String sql = "update tb_admin set admin_password='" + admin_repassword1
            + "' where admin_user='" + admin_user + "'";
    if (!adminDao.operationAdmin(sql)) {
        this.addActionError("修改密碼失敗！！！");
        return INPUT;
    } else {
        request.setAttribute("editPassword", "您修改密碼成功，請您重新登錄！！！");
        return SUCCESS;
    }       
}

}
第一次提問，希望大神們多多指教！小弟也會虛心受教。

最佳回答：

報404狀態碼，表示請求的資源不可用或請求的頁面不存在。你訪問的頁面為admin_index.jsp，而那個web.xml文件設置的為index.jsp，所以你要把web.xml文件的配置改成admin_index.jsp。
