Getting a document from liferay repository

Question

We've setup liferay to use JackRabbit as its document repository. Now what I'm trying to do is retrieve an specific document, and all I know about it is it's name, and sometimes the name of the folder it may be located in.

I know DLFileEntryLocalServiceUtil allows me to retrieve said document but requires me to have it's id before handing it over. My question is, how can I get the id of the file I'm looking for if all I have is the file name and it's location?

Only file name or its folder name will not work for it. You need to have both the information to get Document. Also you will be needing groupId for it.[if you store documents at Global scope then groupId could be themeDispay.getCompanyGroupId()] — Pankaj Kathiriya, Jun 13 '13 at 05:12

Below code snippet could help you,

FileEntry fileEntry = DLAppServiceUtil.getFileEntry(repositoryId, CREATED_FOLDER_ID, fileName);

In above, you have pass repositoryId could be equivalent to groupId which you can get it from themedisplay.getGroupId(), your folderId and fileName

you can get folderId by below code,

        long FOLDER_ID = 0;
        long repositoryId = themeDisplay.getScopeGroupId();
        long parentFolderId = DLFolderConstants.DEFAULT_PARENT_FOLDER_ID;
        List<Folder> lFolder = DLAppServiceUtil.getFolders(repositoryId, parentFolderId);
        for (Folder folder : lFolder)
        {
            if (folder.getName().equalsIgnoreCase(FOLDER_NAME))
            {
                FOLDER_ID = folder.getFolderId();
                break;
            }
        }

Please let me know if it helps
