Trigger is not updateing the :new value in the table

Question

Hi,
I've greated a row trigger that will trigger on insert statements.
The last thing the trigger will do is to update the :NEW.role_id value in the inserted row, see the trigger bellow.
The trigger was mutation so I had to add the 'PRAGMA AUTONOMOUS_TRANSACTION;' to avoid the mutation error.
When performing test with controlled insert statements the trigger is working without problems, but when I my J2EE application is inserting rows to the table the role_id value is nog updated, see the trigger below and the :NEW.role_id := nRole_id; part. The role_id for the new row is empty. What can be the problem?
CREATE OR REPLACE TRIGGER MSP_36.M2_USER_ALERT_INSERT_TRG_SCA
BEFORE INSERT
ON MSP_36.M2_USER_ALERT
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
ex_not_valid_role_name EXCEPTION;
/* Variables */
nAlertTypeId M2_USER_ALERT.alert_type%TYPE;
isLogical      boolean;
validRole     boolean;
nRole_id      M2_ROLE.role_id%TYPE;
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
     BEGIN
          SELECT distinct at.alert_type INTO nAlertTypeId
          FROM M2_USER_ALERT ua, M2_ALERT_TYPE at,M2_ALERT_TYPE_PROPERTIES atp
          WHERE ua.alert_type = at.alert_type
          AND at.alert_type = atp.ALERT_TYPE_ID
          AND ua.alert_type = :NEW.alert_type
          AND upper(atp.property_name) = 'LOGICAL'
          AND upper(atp.property_value) = 'TRUE';
          isLogical := true;
     EXCEPTION
               WHEN no_data_found THEN
               isLogical := false;
               NULL;     
     END;     
IF (isLogical = true) THEN
BEGIN
          SELECT distinct ro.role_id INTO nRole_id
          FROM M2_ROLE ro, M2_USER_ALERT
          WHERE ro.name = :NEW.name;
     EXCEPTION
               WHEN no_data_found THEN
                    validRole :=false;
                    RAISE_APPLICATION_ERROR(-20001,'LOGICAL UserAlert: Role with id'|| nRole_id || ' does not exist.');     
                    NULL;
     END;
     validRole := true;
     IF (isLogical = true AND validRole = true AND :NEW.status = 1) THEN
     INSERT INTO M2_USER_ROLE (user_id,role_id)
     VALUES (:NEW.user_id,nRole_id);
     :NEW.role_id := nRole_id;
END IF;
END IF;
commit;
END;
Many thanks,
Michael

I only get a empty column that include now data. The first insert is working correct so I know that the role_id is valid and working. Can there be problem with commit or my AUTONOMOUS_TRANSACTION running this from JDBC ?
EXAMPLE data from
M2_USER_ROLE
===================
USER_ID = ROLE_ID =
===================
20 = 10040 =
1259756 = 10040 =
===================
Example partly data from
M2_USER_ALERT
=========================================================
USERALERT_ID = USER_ID = ALERT_TYPE = NAME = ROLE_ID =
=========================================================
3725 = 1259756 = 10288 = MG_Test = =
=========================================================
When inserted from the application the role_id is empty and I've taken the same SQL from the library cache and run it with same BIND variables and then it's working.
