  <p>start.xhtml includes the following form code:</p>
  
  <pre><code>&lt;h:form enctype="multipart/form-data"&gt;
    &lt;p:fileUpload fileUploadListener="#{sentimentAnalysis.analyse}" /&gt;
    &lt;p:commandButton value="submit" ajax="false"/&gt;
    &lt;h:messages /&gt;
  &lt;/h:form&gt;
  </code></pre>
  
  <p>And my Bean contains the following code:</p>
  
  <pre><code>@Named
  @ViewScoped
  public class SentimentAnalysis {
    private UploadedFile uploadedFile;
  
  public void analyse(FileUploadEvent event) throws IOException {
    uploadedFile = event.getFile();
    readFile(uploadedFile);
  }
  </code></pre>
  
  <p>I already tried putting the commons-fileupload and commons-io jars in the WEB-INF lib folder (which should not be necessary if running Maven), but to no avail. Commons-io is not mentioned in the pom.xml, but is mentioned in the 'dependency hierarchy' in Eclipse.
  BTW, I'm running Glassfish 3.0, JSF 2.0, primefaces and Eclipse Juno.</p>
  
  <p>Does anyone know what's wrong? Why doesn't it recognize the fileUploadFilter?</p>
  
  <p>Thanks in advance,
  Rory</p>
