Problem importing stuff

[Luca Lupo，修改在11 年前。]

Hi Guys,

Eclipse gives me problem in importing the following classes:

import com.liferay.portlet.journal.model.JournalFolder;
import com.liferay.portlet.journal.model.JournalFolderConstants;
import com.liferay.portlet.journal.service.JournalFolderLocalServiceUtil;
import com.liferay.portlet.journal.service.persistence.JournalFolderUtil;

Any idea why?

Thanks

Luca
