Overrid JBO messages in multiple languages

Question

Hello,
platform : JDev 10.1.2 with UIX
We need to have custom error messages for my application.
In Jdeveloper help in section 'Customizing Error Messages ' the mechanism to override existing JBO messages in well documented.
BUT. How to translate these messages to another language, French in my case?
because I get the default JBO French message.
Any pointers and sample code will also be helpful.
regards

For displaying message, it better to use message class instead of using otr.
Using transcation se91 create a message class and messages, this can be called in WDA
  get message manager
  DATA lo_api_controller     TYPE REF TO if_wd_controller.
  DATA lo_message_manager    TYPE REF TO if_wd_message_manager.
  lo_api_controller ?= wd_this->wd_get_api( ).
  CALL METHOD lo_api_controller->get_message_manager
    RECEIVING
      message_manager = lo_message_manager
  report message
  CALL METHOD lo_message_manager->report_t100_message
    EXPORTING
      msgid                    = (Name of the Message Class)
      msgno                    = (Message Number)
      msgty                    = (E - Error, W - Warning...)
     p1                       =
     p2                       =
     p3                       =
     p4                       =
     msg_user_data            =
     is_permanent             = ABAP_FALSE
     scope_permanent_msg      = CO_MSG_SCOPE_CONTROLLER
     view                     =
     show_as_popup            =
     controller_permanent_msg =
     msg_index                =
     cancel_navigation        =
This will display the message in logon language.
