  // ---- General idea:
  // In order to set the caller ID, we have to know in which global CONTEXT
  // we are. In an EJB CONTEXT, there should be an EJBContext that holds the
  // caller ID. In a standard J2SE CONTEXT, we consider that the
  // SecurityContext class has been used and that it holds the caller ID.
  // In this last case, (J2SE), the standard way for setting
  // the caller ID in the SecurityContext class is to use JAAS with the
  // StorageLoginModule. Note that this is not required. Any other mechanism
  // can be used. The requirement is that the SecurityContext.getCallerId()
  // should return the proper value. See SecurityContext class for more
  // informations.
