title: Getting a document from liferay repository
body: <p>We've setup liferay to use JackRabbit as its document repository. Now what I'm trying to do is retrieve an specific document, and all I know about it is it's <code>name</code>, and sometimes the name of the <code>folder</code> it may be located in. </p>
  
  <p>I know <code>DLFileEntryLocalServiceUtil</code> allows me to retrieve said document but requires me to have it's <code>id</code> before handing it over. My question is, how can I get the <code>id</code> of the file I'm looking for if all I have is the file <code>name</code> and it's <code>location</code>?</p>
