How to get a DLFileEntry from a velocity script?

[Luis Rodríguez Fernández，修改在14 年前。]

Hi everyone!

We get the typical "News" section in our portal. The detail of each one is made by date, title, content and one or more documents from the document library.

The problem is that we can't get each of theses documents. We have tried with the next code:

#set($dlFileEntryUtil = $serviceLocator.findExceptionSafeService('com.liferay.portlet.documentlibrary.service.persistence.DLFileEntryUtil'))

#set($fileEntry = $dlFileEntry.getFileEntryByUuidAndGroupId($fileEntryUuid,$fileEntryGroupId))

It seems that we can get the service but their methods don't work!

Any idea?

Thanks,

Luis

Luis Rodríguez Fernández:

#set($dlFileEntryUtil = $serviceLocator.findExceptionSafeService('com.liferay.portlet.documentlibrary.service.persistence.DLFileEntryUtil'))

#set($fileEntry = $dlFileEntry.getFileEntryByUuidAndGroupId($fileEntryUuid,$fileEntryGroupId))

It looks like you have a typo. Try:

#set($fileEntry = $dlFileEntryUtil.getFileEntryByUuidAndGroupId($fileEntryUuid,$fileEntryGroupId))

Hi,

please try as follows:

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

Above works for me. Using .findExceptionSafeService instead, doesn't work with my environment either. I don't know why.
Using $getterUtil.getLong($groupId)) for long Types maybe important too.

I'm running liferay 5.2.3 at rev. 33675 from svn.branch

Good luck.

Cheers,
Thomas

Thanks!!!

Both were right. I had a typo error and with 5.2.3 I can't use serviceLocator.findSafeExceptionService.
