ADT for Media gallery Portlet

[krishna mohan mathakala，修改在7 年前。]

Hi I want to create ADT for my media gallery portlet. My requirement is as below

I have a folder called Root which internally contains 2 more folders(Folder 1 with some images and Folder 2 with some images) .
With my ADT I want to display first image from folder1 and first image from folder 2 on default media gallery portlet.
If the user click on the first image then navigate the user to filder 1 and display all the images in that folder and same for the folder2.

I am not able to get the root folder id from the service.

I tried the following way but not able to get the root folder id.

#set ($folderLocalService =$serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFolderLocalService"))
#set ($folderId = $folderLocalService.getFolder($groupId,0,"Root").getFolderId())

Is there any way to get the root folder id ?

Thanks in advance.

Hi Krishna,

The default root folder Id is 0, as defined in DLFolderConstants.java. This folder does not actually "exist" (i.e. you won't find it with the service).
