APEX and ORA-24247: network access denied by access control list (ACL)

Question

Hi,
I try to send email with APEX.
I have enter the parameters of my mail server and activate the email on my application.
I have follow the APEX installation guide and apply the script given in the "Granting Connect Privileges" section.
When I try to send email or make a subscription, I don't receive any email and can see this error in the table "WWV_FLOW_MAIL_LOG"
+"MAIL_TO","MAIL_FROM","MAIL_REPLYTO","MAIL_SUBJ","MAIL_CC","MAIL_BCC","MAIL_SEND_ERROR","LAST_UPDATED_BY","LAST_UPDATED_ON","SECURITY_GROUP_ID"+

Do you see what is wrong in my configuration ?
I use APEX 4.1, Oracle 11g.
The script that I have apply is :
DECLARE
ACL_PATH  VARCHAR2(4000);
ACL_ID    RAW(16);
BEGIN
-- Look for the ACL currently assigned to '*' and give APEX_040100
-- the "connect" privilege if APEX_040100 does not have the privilege yet.
SELECT ACL INTO ACL_PATH FROM DBA_NETWORK_ACLS
WHERE HOST = '*' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;
-- Before checking the privilege, make sure that the ACL is valid
-- (for example, does not contain stale references to dropped users).
-- If it does, the following exception will be raised:
--+
-- ORA-44416: Invalid ACL: Unresolved principal 'APEX_040100'
-- ORA-06512: at "XDB.DBMS_XDBZ", line ...
--+
SELECT SYS_OP_R2O(extractValue(P.RES, '/Resource/XMLRef')) INTO ACL_ID
FROM XDB.XDB$ACL A, PATH_VIEW P
WHERE extractValue(P.RES, '/Resource/XMLRef') = REF(A) AND
EQUALS_PATH(P.RES, ACL_PATH) = 1;
DBMS_XDBZ.ValidateACL(ACL_ID);
IF DBMS_NETWORK_ACL_ADMIN.CHECK_PRIVILEGE(ACL_PATH, 'APEX_040100',
+'connect') IS NULL THEN+
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE(ACL_PATH,
+'APEX_040100', TRUE, 'connect');+
END IF;
EXCEPTION
-- When no ACL has been assigned to '*'.
WHEN NO_DATA_FOUND THEN
DBMS_NETWORK_ACL_ADMIN.CREATE_ACL('power_users.xml',
+'ACL that lets power users to connect to everywhere',+
+'APEX_040100', TRUE, 'connect');+
DBMS_NETWORK_ACL_ADMIN.ASSIGN_ACL('power_users.xml','*');
END;
+/+
COMMIT;
Thanks for your help,

Hi,
You need to grant privilege to the user.
i.e add principal
You can use script :
DECLARE
ACL_ID   RAW(16);
CNT      NUMBER;
BEGIN
-- Look for the object ID of the ACL currently assigned to ''*
SELECT ACLID INTO ACL_ID FROM DBA_NETWORK_ACLS
WHERE HOST = '' AND LOWER_PORT IS NULL AND UPPER_PORT IS NULL;*
-- If just some users referenced in the ACL are invalid, remove just those
-- users in the ACL. Otherwise, drop the ACL completely.
SELECT COUNT(PRINCIPAL) INTO CNT FROM XDS_ACE
WHERE ACLID = ACL_ID AND
EXISTS (SELECT NULL FROM ALL_USERS WHERE USERNAME = PRINCIPAL);
IF (CNT > 0) THEN
FOR R IN (SELECT PRINCIPAL FROM XDS_ACE
WHERE ACLID = ACL_ID AND
NOT EXISTS (SELECT NULL FROM ALL_USERS
WHERE USERNAME = PRINCIPAL)) LOOP
UPDATE XDB.XDB$ACL
SET OBJECT_VALUE =
DELETEXML(OBJECT_VALUE,
*'/ACL/ACE[PRINCIPAL="'||R.PRINCIPAL||'"]')*
WHERE OBJECT_ID = ACL_ID;
END LOOP;
ELSE
DELETE FROM XDB.XDB$ACL WHERE OBJECT_ID = ACL_ID;
END IF;
END;
REM commit the changes.
COMMIT;
Or you need to add privilege to specific user/schema using following script:
BEGIN
DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE (
acl          => 'aclfilename.xml',
principal    => 'databaseuser',
is_grant     => TRUE,
privilege    => 'connect',
position     => null);
COMMIT;
END;
Please execute this code after connect as sysdba user.
