Webremote and database persist

[bashan]

Hi,

I am having a little problem persisting one of my objects in a webremote method.
This is my method:

  @WebRemote
  public void countView(Integer videoId)
  {
    Video video = videoDAO.getVideo(videoId);
    video.setViews(video.getViews() + 1);
    myDB.persist(video);
  }

The code is called and no exception is raised, but object is not persisted to database.
Without using webremote I have no problem persisting the object.
Does anyone know what is going on? Maybe the transaction is not automatically comitted when using webremote?

Thanks,
Guy.

Does anyone has any clue about this problem?

Actually, I found a working solution, but I am not sure I understand why the original code is not working. This is the solution:

  @WebRemote
  public void countView(Integer videoId) throws Exception
  {
    Transaction.instance().begin();
    Video video = videoDAO.getVideo(videoId);
    video.setViews(video.getViews() + 1);
    nikoniansDatabase.persist(video);
    Transaction.instance().commit();
  }
