我使用Netbeans 6.8,并试图通过使用小米植被和JPA来获取用户界面。 我不能说,

@Action
public void save( ActionEvent event )
{
    mSearchMetawidget.save();
}

这一说明在进口后加上“不相容的类型”错误。

import org.metawidget.inspector.impl.actionstyle.Action;

What to do? How can I add an action related to my User entity. I want to do "register" action. Thanks in advance

我认为,“行动”是一种梅塔维兹诺言,由于进口错误而成为头痛。 我现在谈谈这个问题。 我还需要增加周转图书馆。 “行动说明”属于SwaingAppFramework。

事实上,我们要更新由梅塔维德人自动提取的用户界面数据库记录。 我们设立了实体班级,并试图加以修改,以达到目的。 我们怎么能向我们的用户接口班说,如果用接口领域的已输入数据对一个子子施加压力,那么这些记录就会更新?

感谢。

我想利用JPA的实体管理。 是否应在纽顿行动清单中添加与实体管理有关的代码? 在以下类别中,其听众是“User”

我有一个实体类别,即用户。
