To capture the error after processing LOGON function

Question

Dear friends
I want to capture the exception after the execution of the LOGON function. Scenario i need to capture is when the user account been locked, password expired and password will expire in N days.
I made the user account locked and password expired through backend.
In the when-button-pressed trigger I make a call to the procedure where the Logon function is coded
Function P_CONNECT (io_message IN OUT varchar2)
Account_locked EXCEPTION;
Password_expired EXCEPTION;
Password_will_expire EXCEPTION;
PRAGMA Exception_Init (Account_locked, -28000);
PRAGMA Exception_Init (Password_expired, -28001);
PRAGMA Exception_Init (Password_will_expire, -28002);
begin
begin
Logon( L_username,
L_string,
FALSE);
exception
when Account_locked then
io_message := 'acc_loc';
return FALSE;
end;
if form_success then
/* code with certain activities*/
end if
end;
During the execution of this procedure, i tried to capture the account_locked for example. I couldnt.
Then I created on_error trigger at the form level. I couldnt able to capture as well.
Also I need the form errorcode (FRM 4....) equvalent to -28000. -28001, -28002.
Or any other suggestions are welcome
Thanks

Hi,
I got struck with the similar case. i.e.., if the user enters the login details incorrectly or login details are not provided then I've used exec_sql package. This package is been used to check whether a connection can be established or not. If the connection cannot be established then I'll pop up a message saying that the login details are incorrect.
Though my case is different than that of yours, but i think that this will give u some idea to kick start to your solution.
