Velocity template DLFileEntry

[Adri Meijer, geändert vor 9 Jahren.]

Hello,

I want to use this template, but it doesn't work (see below).

## instance of DLFileEntry service
#set($fileService = $serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService"))

## get group id
#set($gid = $getterUtil.getLong($request.get("theme-display").get("scope-group-id")))

##search documents by folderId
#set($fid = $getterUtil.getLong($folder.folderId))
#set($files = $FileService.getFileEntries($gid, $fid, -1, -1, null))

#foreach($doc in $files)
<p>$doc.getTitle()</p>
#end

<p>$gid</p>
<p>$fid</p>
<p>$files</p>

I am using Liferay 6.2 CE ga2. The variables $gid and $fid can be found.
I guess that this line #set($files = $FileService.getFileEntries($gid, $fid, -1, -1, null)) is not correct for Liferay 6.2.

Can anyone help me ?

Hey Adri,

My initial guess would be that the $serviceLocator variable is not set. You can check this just by printing out $serviceLocator on the page and see if it works.

In Liferay 6.2 the service locator is a restricted variable by default. If you look in portal.properties you can see:

velocity.engine.restricted.variables=serviceLocator

If you want to use it you can set that setting to blank in your portal-ext.properties like this:

velocity.engine.restricted.variables=

Hope that helps,
Ryan

Hello Ryan,

Thanks for your reply. The solution you gave me does not work. The service locator can determine the variable (@bf308f3)

Web Content Display
Options
Gid :10181
Fid :0

$files

Service Locator :com.liferay.portal.template.ServiceLocator@bf308f3

The problem is that $files are not found. The $files gave in this example mutiple file names.

#set($files = $FileService.getFileEntries($gid, $fid, -1, -1, null))

#foreach($doc in $files)
<p>$doc.getTitle()</p>
#end

Is this a typo -

#set($fileService = $serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService"))
#set($files = $FileService.getFileEntries($gid, $fid, -1, -1, null))

The set defines a fileService with small F. And when you access you call $FileService

Hi Tina,

#set($fileService = $serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService"))
#set($files = $FileService.getFileEntries($gid, $fid, -1, -1, null))

how to write above two lines in liferay 7 using freemarker.

Can you please help in this?

Thanks

I would try something like this:
<#assign fileService = serviceLocator.findService("com.liferay.portlet.documentlibrary.service.DLFileEntryLocalService")) />
<#assign files = FileService.getFileEntries(gid, fid, -1, -1, null)) />
