title: how to add language to my DSpace?
body: <p>I want to add "arabic" to my DSpace.</p>
  
  <p>I configure this file :  </p>
  
  <pre><code>[dspace]/config/dspace.cfg  
  </code></pre>
  
  <p>with this line:</p>
  
  <pre><code>webui.supported.locales = en, de, ar
  </code></pre>
  
  <p>Then I build Dspace and restart Tomcat.</p>
  
  <p>But I can't find this file :</p>
  
  <pre><code> "Messages.properties" at   
  [dspace-src]/dspace/modules/jspui/src/main/resources/Messages.properties  
  </code></pre>
  
  <p>and how German can appear on my DSpace wherever I can't find  </p>
  
  <pre><code>"Messages_de.properties" at  
  [dspace-src]/dspace/modules/jspui/src/main/resources/Messages_de.properties 
  </code></pre>
  
  <p>Will I have other strange problems to customize my DSpace with arabic?</p>
