Initialize serviceContext without request

hi
I create Service Context object and used it in the addFolder method in the DLAppServiceUtil class and I get the Principal is null exception
my code is :

long companyId = CompanyLocalServiceUtil.getCompanyByMx( PropsUtil.get( PropsKeys.COMPANY_DEFAULT_WEB_ID ) ).getCompanyId();
Group group = GroupLocalServiceUtil.fetchGroup( companyId, GroupConstants.GUEST );
long groupId = group.getGroupId();
ServiceContext serviceContext = new ServiceContext();
serviceContext.setScopeGroupId( groupId );
serviceContext.setCompanyId( companyId );
DLAppServiceUtil.addFolder( groupId, DLFolderConstants.DEFAULT_PARENT_FOLDER_ID, "ALI", "---", serviceContext );

Hi, 
​​​​​​​This may be because the user from which you are doing this might not have permission to add folder to the repository.
Try once setting userid also  in serviceContext.setuserId( userId); and check

If this code isn't initiated from a request (eg startupAction, or scheduled job), then it rightly throws a principal is null exception which means there's no user doing the action. Usually if this is the case, it probably means you don't want to check permissions anyway because you're controlling the execution of the code. So you should call the DLAppLocalService method which does not check permissions.

Hi,
 You can set the permission checker  and see
PermissionChecker permissionChecker  = PermissionCheckerFactoryUtil.create(adminUser);
PermissionThreadLocal.setPermissionChecker(permissionChecker);
