If anyone at Liferay can offer the community guidance here, this is a real pain point for a lot of template developers.

DLFileEntryLocalServiceUtil exists here:
https://docs.liferay.com/portal/7.0/javadocs/portal-kernel/com/liferay/document/library/kernel/service/DLFileEntryLocalServiceUtil.html

Strange behaviour of StaticUtils or we are missing something.

StaticUtil works,
for example if I insert this code it works.

<#assign serviceContextThreadLocal = staticUtil["com.liferay.portal.kernel.service.ServiceContextThreadLocal"] />

I have a "class not found" error , it seems it is not able to found the class DLFileEntryLocalServiceUtil

It worked with serviceLocator. Still can't understand why staticUtil is not working.

Thank you Massimo for the quick reply.

Instead of staticUtil try serviceLocator

&lt;#assign dlFileEntryService = serviceLocator.findService('com.liferay.document.library.kernel.service.DLFileEntryService') /&gt; 
&lt;#assign file = dlFileEntryService.getFileEntryByUuidAndGroupId(uuId,groupId)  &gt;

I never used a config file inside bundle/osgi/config, I added these lines in my portal-ext.properties

freemarker.engine.restricted.classes=
freemarker.engine.restricted.packages=
freemarker.engine.restricted.variables=

I also created the cfg file in bundle/osgi/config as mentioned here but still no luck...

Even when setting "restrictedVariables = " I still get the same error or my portal faces Internal server error 500 and I have to recove it by deleting the related entries in configuration_ table. Check this issue for more details.

I am using Liferay 7.0 GA4

Can't fetch documents with freemarker on templates

Hi,
I created a structure which contains documents and also created the related template.
In the template I added freemarker code to fetch the documents these but is not working.

My code is

    &lt;#assign fileEntry = staticUtil["com.liferay.document.library.kernel.service.DLFileEntryLocalServiceUtil"]&gt;
    &lt;#assign file = fileEntry.getFileEntryByUuidAndGroupId(uuId,groupId)&gt;

and the error

09:16:07,089 ERROR [http-nio-8080-exec-9][runtime:60] Error executing FreeMarker template
FreeMarker template error:

In order to use statitUtil I went to Control Panel -> Configuration -> System Settings -> Foundation -> FreeMarker Engine -> Restricted Variables.
and i deleted staticUtil and all the restricted Variables and classes. But no luck... Still getting this error...

Any ideas?
