title: Stemming with WordNet using JWNL - Unable to install dictionary
body: <p>I am trying to stem a string using WordNet with the JWNL API. When I try to load the dictionary it gives me a FileNotFoundException. </p>
  
  <p>This is the code initializing the dictionary:</p>
  
  <pre><code>public static void Initializer(){
      try {
          JWNL.initialize(new FileInputStream("file_properties.xml"));
          dictionary = Dictionary.getInstance();
          morphPro = dictionary.getMorphologicalProcessor();
      }
      catch(FileNotFoundException e){
          e.printStackTrace();
  
      } catch (JWNLException e) {
          e.printStackTrace();
      }
  }
  </code></pre>
  
  <p>And this is what I get:</p>

  <p>I am pretty sure that it has something to do with the path, but I can not find out exactly what is wrong, since I changed the file <code>properties.xml</code> to use <code>C:\WordNet\2.1\dict\</code> - so that should be okay?</p>
