Here's one solution, it depends a bit, where you start. If you already have a fileentry, you also can use the approach above and concatenate the url yourself. It works pretty well, I have used that approach now for years, never run into problems.
If you have just an ADT, some numbers, an assetentry, ... you need to use the serviceLocator:

Another approach is to use a Template Context Contributor:
It allows you to inject services into ADTs. You could simply write ${myhelpercontributor.getURLForFile(entryId)} to get the url.

Please note that it only works "as expected" from 7.0.0 DXP SP7 and up:

Hi,

This worked for me:



    public static String getDLFileURL(DLFileEntry file) {
        return "/documents/" + file.getGroupId() + BACKSLASH + file.getFolderId() + BACKSLASH
            + file.getTitle() + BACKSLASH + file.getUuid();
    }

Hey,

I found a solution that seems to work :

String url = portalURL + "/c/document_library/get_file?uuid=" + document.getUuid() + "&amp;groupId=" + document.getGroupId();

Hey Everybody,

I have a problem getting a download-URL for an element of the document-library.

First I did it that way:

Java

DLFileEntry fe = DLFileEntryLocalServiceUtil.getDLFileEntry( readingConfirmation.getDocumentId() );
fileEntryUUId = fe.getUuid()

JSP:

<a href="<%= themeDisplay.getPortalURL() + themeDisplay.getPathContext() + &quot;/documents/&quot; + themeDisplay.getScopeGroupId() + StringPool.SLASH + fileEntryUUId %>"></a>

It worked when trying to download a file inside the same site - but now I placed the portlet to download the file inside "my-dashboard", which is a group-site - and then the ressource cannot be found . It is not a matter of rights - the URL seems not to be generated in the right way.

Can someone help me to generate an URL when I have the FileEntry Object or its ID - no matten in what site I am?

Also tried that one :

DLUtil.getPreviewURL(fileEntry, fileEntry.getFileVersion(), themeDisplay, StringPool.BLANK, false, true)

Doesnt seem to work either

I also have the group/site ID - but how to use it to generate the URL?

Thanks in advance!
