Hello everybody.

I'm stuck with this seemingly simple task:

Get file names (or size or owner or ID or else) from a WCD/Journal portlet using a document_library (repeatable) field.

I tried search around quite a lot but couldn't find a suitable and ready-to-go solution.

Here's my WCD structure:

<root>
<dynamic-element name='content' type='text_area' index-type='' repeatable='false'>
<meta-data>
<entry name="displayAsTooltip"><![CDATA]></entry>
<entry name="required"><![CDATA]></entry>
<entry name="instructions"><![CDATA[]]></entry>
<entry name="label"><![CDATA]></entry>
<entry name="predefinedValue"><![CDATA[]]></entry>
</meta-data>
</dynamic-element>
<dynamic-element name='files' type='document_library' index-type='' repeatable='true'>
<meta-data>
<entry name="displayAsTooltip"><![CDATA]></entry>
<entry name="required"><![CDATA]></entry>
<entry name="instructions"><![CDATA[]]></entry>
<entry name="label"><![CDATA[DocumentLibraryField]]></entry>
<entry name="predefinedValue"><![CDATA[]]></entry>
</meta-data>
</dynamic-element>
</root>

and the sample template trying to list link and file names:

Content is:<br/>
$content.getData()
<br/>
Files are:
<br/>
<ul>
#foreach ($ListItem in $files.getSiblings())

<li><a href='$ListItem.getData()'> ??</a> </li>

#end
</ul>


Content data is showing up and I can get the "files" fields contents (which are document library links without the host name, as per selection fron WCD editor)
I get something like this:

Content is:
Yocontent


Files are:
?? (<-- Note: link IS working here with url: http://myLiferayHost.here/documents/16292/18041/myUploadedFilename.here.pdf
??

I guess I need some service here, somehing like (velocity):

#set($dlFileEntryUtil = $serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService"))
#set ($longGroupId = $getterUtil.getLong($groupId))
#set($fileEntry = $dlFileEntryUtil.getFileEntryByUuidAndGroupId($uuid,$longGroupId))
(from here )

but the question is:

What is the correct way to create a FileEntryXXX velocity object with the correct parameters if I (apparently) have only the (web) file path (such as /documents/16292/18041/myUploadedFilename.here.pdf) ?

Do I need some URL parsing? Or there's a dedicated Liferay way ?
What class and method(s) to use?

Config:

Liferay 6.0.10 from Trunk (30 sept 2010 build)
Java 6
Linux CentOS

P.S= I put an empty property journal.template.velocity.restricted.variables=
in portal-ext.properties


Thanks in advance!

Nobody has a little hint? ... I guess it's a common task... :-(((((


While searching meanwhile, I made up my mind that you need to parse the journal document library fields' URLs according to the FriendlyUrlMapping naming strategy. Then there's a possibility to che a FileEntry handle (still wondering if there's a "standard" LR way...)

Supposing I am right, can somebody please post a quick and tested LR/Velocity code snippet to parse a document library URL?

Even if this thread is quite "ancient", I'd love to contribute the solution I used for it.

First off, make sure you have the serviceLocator enabled in your portal-ext.properties:


Suppose the document library link is stored in a field called 'doc'.



That's it, hope this helps other developers!

Thanks for posting your solution to the 'ancient' thread - it saved me tons of time!!
