    Seam FileUpload Problem

    Yogesh Novice

      Hello,
      I am trying to get the Seam File Upload example (from the wiki) working but i am stuck on one point!!


      My configs are as follows:

      My web.xml

      
      <?xml version="1.0" ?>
      <web-app xmlns="http://java.sun.com/xml/ns/j2ee"

       version="2.4">

       will be added as url parameters.

       <description>
       A very common problem in configuring MyFaces-web-applications
       is that the Extensions-Filter is not configured at all
       or improperly configured. This parameter will check for a properly
       configured Extensions-Filter if it is needed by the web-app.
       In most cases this check will work just fine, there might be cases
       where an internal forward will bypass the Extensions-Filter and the check
       will not work. If this is the case, you can disable the check by setting
       this parameter to false.

      My WAR file contains the directory "files" where i want to store my uploaded files. As such the following tomahawk config in my web.xml
       <init-param>
       <param-name>uploadRepositoryPath</param-name>
       <param-value>/files</param-value>
       <description>Set the path where the intermediary files will be stored.
       </description>
       </init-param>
      



      However, i get the following error message in my logs when i try to upload a file:

      
      org.apache.commons.fileupload.FileUploadException: Processing of multipart/form-data request failed. \files\upload_00000000.tmp (The system cannot find the path specified)
      



      Can anyone suggest what could me wrong in the above configs ??
