How to access a folder in DL via VM template.

I have created a folder in the document library off of root - "MyFolder".

I have been trying to access it with no luck so far. This shouldn't be so hard. This is the code I am using to just access the folder:


#set ( $DLFolderLocalService=$serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFolderLocalService"))
#set ( $myFolder = $DLFolderLocalService.getFolder(16348) )

Folder Name: $myFolder.getName() <br/>

But instead I get $myFolder.getName printed out literally.

Any help on how to access this folder and it's contents?

I believe if $myFolder resolves to null, Velocity will treat it as inline text rather than as a reference to resolve.

Since you don't get a failure on an NPE on the second #set, I'm guessing the service was found but it returned null for myFolder.

In the com.liferay.portal.bean.VelocityBeanHandler class, if a bean (in this case your DLFolderLocalService instance) throws an exception, it is swallowed up and a null is returned.

The key here is figuring out why your call to getFolder(16348) is failing.

Thanks for the reply.

I found that folder id by looking at the URL in the control panel. Is that not the correct way to get the folder id? I don't the id displayed any where else, but I think making sure I have the correct folder id is the first step.

When I hover over the folder in the DL I get this:

http://localhost:8080/group/control_panel/manage?p_p_id=20&p_p_lifecycle=0&p_p_state=maximized&p_p_mode=view&doAsGroupId=14209&refererPlid=16323&_20_struts_action=%2Fdocument_library%2Fview&_20_viewEntries=true&_20_viewFolders=true&_20_folderId=16348

I am choosing the correct folderId, yes?

Looks like the right one, but you have to remember that what is going on at the portlet level may be different than just calling getFolder(16348)...

If you try a similar sort of thing in a JSP page, there you should see whatever exception is probably getting thrown from the call, and that will lead you toward the solution...

One more thing, where would I find the source for the asset publisher or Document and Media portlets?

They're part of Liferay and would be available in the source download.

To find the id value, I usually just look in the database table. If you're using the default database, it's kind of difficult to view it online so I usually setup a mysql.

Just download liferay's source code.
jsp files are in respective folders in portal-web\docroot\html\portlet

Java codes are in

and

\portal-impl\src\com\liferay\portlet
