Permission Checker not Initialized !! Liferay 6

[Hakan Görmüş，修改在13 年前。]

Hi all,
i am tring to get folder with DlFolderService. Tring like below ;

DLFolderService folderService = DLFolderServiceUtil.getService();
DLFolder folder = folderService.getFolder(folderPrimeryKeyId);

But i am getting ;

com.liferay.security.auth.PrincipalException : PermissionChecker not initialized 
at 
com.liferay.portal.services.base.PrincipalBean.getPermissionChecker(PrincipalBean.java:81)
at com.liferay.portlet.documentlibrary.service.impl.DLFolderServiceImpl.getFolder(DLFolderServiceImpl.java:166)...

I looked the source code ;

public DLFolder getFolder(long folderId)
		throws PortalException, SystemException {

		DLFolder folder = dlFolderLocalService.getFolder(folderId);

		DLFolderPermission.check(
			getPermissionChecker(), folder, ActionKeys.VIEW);

		return folder;
	}

There is a permission check but how can i initialize PermissionChecker ??? Any idea ?

*LocalService -> No permission checks
*Service -> Permission checks

You probably want to use DLFolderLocalService.

Usually the permissionchecker is initialized with the current user. So, you can simply assume, it's there. That's not true in some cases, e.g. when a scheduled job is started.
