We are using JBOSS 6.1 and the JSF implementation is 1.2. We are also using Richfaces 4.3.7. The problem I am having is when using the the rich:fileUpload component. Everything works fine until I select "Upload". I then receive the exception (see attachment) in the server application log.

My xhtml contains the following:

<rich:fileUpload fileUploadListener="#{fileUploadBean.uploadFile}" addLabel="Browse ..." clearAllLabel="Clear" id="upload" acceptedTypes="xml"

               ontyperejected="alert('Only XML files are accepted');"  noDuplicate="true" style="width:820px">

</rich:fileUpload>

My Bean listener method contains the following :

public void uploadFile (FileUploadEvent event) throws Exception {

        try {

        log.info("Entered uploadFile");

        if (event == null) {

            log.info("FileUploadEvent is null");

        }

        uploadedFile = event.getUploadedFile();

        fileName = uploadedFile.getName();

        log.info("FileName: " + fileName);

        }

        catch(Exception e) {

            log.info("exception is: " + e.getMessage());

        }

    }

I really don't understand what the exception is complaining about. What is null  - JBWEB000236: Servlet.service() for servlet Faces Servlet threw exception: java.lang.NullPointerException ?

I have been debugging this for hours and I don't see what I am doing wrong.

I would appreciate your feedback.

Thank you.
