Workflow notification called by databse trigger

Question

Hi,
I have a question about Oracle Workflow notification mailer.
Can we use an Oracle database trigger or Oracle Form's trigger
to run or execute oracle workflow to send notification mailer?
For example, if I execute a DML (insert or update) using SQL*Plus to modify a table.
Can the database trigger act as a caller to send mail through workflow API?
Thanks.

ok I have simmilar problem
Created workflow.
Want to send notification from forms.
have procedure in the database
PROCEDURE set_wf_t IS
BEGIN
WF_ENGINE.Threshold:= -1;
END;
code in the form looks like this.
Declare
ItemType varchar2(30) := 'MY_WF';
ItemKey varchar2(80) := 'ID-'||to_char(SysDate, 'MM/DD/YYYY HH24:MI:SS');
BEGIN
If values='T' then
--send email
SET_WF_T; --Setting value WF_ENGINE.Threshold:= -1
wf_engine.CreateProcess( ItemType => ItemType,
ItemKey => ItemKey);
wf_engine.SetItemAttrText ( itemtype => itemtype,
itemkey => itemkey,
aname => 'NUMBER',
avalue =>:BLOCK.NUMBER);
wf_engine.SetItemAttrText ( itemtype => itemtype,
itemkey => itemkey,
aname => 'MESSAGE_SUB',
avalue =>'Message Subject');
wf_engine.SetItemAttrText ( itemtype => itemtype,
itemkey => itemkey,
aname => 'MESSAGE_BODY',
avalue =>'Message text here');
wf_engine.setitemattrtext (itemtype => itemtype,
itemkey => itemkey,
aname => 'OWNER',
avalue => v_owner);
     wf_engine.StartProcess( itemtype => itemtype,
itemkey => itemkey );
          END IF;     
END;
The problem is that I don't receive email.
And I don't see notification in the status monitor.
I receive email when i run process manually from DEVELOPER STUDIO
What I am doing wrong?
Thank you
