Problem related to button action

Question

Hello,
I'm trying to upload a file into server, I got the code from the net. When I try to run my application from my local server, everything is just fine and works.
When I deploy my application on our remote server, I got the following problem :
   - If I don't choose a file to upload, the action is executed
   - Else nothing happend, as if I didn't enter a file.
Have anyone encountred such a problem?
Thanks in advance for your help.

Thank you for replying John.
Here is my code :  
public void onActionUserMapped(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionUserMapped(ServerEvent)
     IWDMessageManager msgmgr = wdComponentAPI.getMessageManager();
     IPrivateUploadFileView.IContextElement element = wdContext.currentContextElement();
     msgmgr.reportSuccess("Entrée dans la méthode.");     
     //if a file in the FileUpload field exists
     if (element.getFileResource() != null)
        IWDResource resource = element.getFileResource();
        String fileextension = resource.getResourceName();
        int cut = fileextension.lastIndexOf(".");
        String ext = fileextension.substring(cut+1,fileextension.length());
        if(ext.equals("csv"))
            File fp = new File (resource.getResourceName());
            try
                 if (fp.exists())
                     msgmgr.reportException("Il existe déjà un fichier avec le même nom sur le serveur, changez le nom du fichier et réessayer SVP",true);
                 else
                       fp.createNewFile();
                       wdContext.createContextElement().setFilePath(fp.getAbsolutePath());
                       FileOutputStream fos = new FileOutputStream(fp);
                       BufferedOutputStream bos = new BufferedOutputStream(fos);
                       InputStream fileInputStream = resource.read(false);
                       int noOfBytes = fileInputStream.available();
                       byte[] byteArray = new byte[noOfBytes];
                       fileInputStream.read(byteArray, 0, noOfBytes);
                       bos.write(byteArray);
                      bos.flush();
                       bos.close();
                       //On vide la structure au cas où elle a déjà été utilisée
                       wdThis.wdGetMappingPortalUsersController().clearBeforeMappingNode();
                       wdThis.wdGetMappingPortalUsersController().clearAfterMappingNode();
                       wdThis.wdGetMappingPortalUsersController().clearErrLogs();     
                       //On lit le fichier uploadé
                       wdThis.wdGetMappingPortalUsersController().readCSV(wdContext.createContextElement().getFilePath());
                       //On supprime le fichier car les données sont recopiées dans le noeud du contexte.
                       fp.delete();
                       wdThis.wdGetMappingPortalUsersController().simulateMappingCreation();
           catch(FileNotFoundException fnfe)
                      msgmgr.reportException("Error while reading file : " + fnfe.getMessage(),true);
           catch (IOException ioe)
                  msgmgr.reportException("Error while reading file : " + ioe.getMessage(),true);
      else
            msgmgr.reportException("Please, choose a CSV file",true);
   else
          //Si pas de fichier dans FileUpload field
          msgmgr.reportException("Please, select a file first",true);
   msgmgr.reportSuccess("Sortie de la méthode");          
   element.setFileResource(null);
   wdThis.wdFirePlugToMappedUsers();
    //@@end
Thanks in advance for you help.
