Urgent:why portal30 DAD can not invoke procedure through url

Question

My portal version is 3.0.9
I found an mod/plsql problem .I created a procedure named current_user like this :
create or replace procedure current_users
AS
ignore boolean;
BEGIN
htp.htmlopen;
htp.headopen;
htp.title('Current Users');
htp.headclose;
htp.bodyopen;
htp.header(1, 'Current Users');
htp.bodyclose;
htp.htmlclose;
END;
And I created it in portal30 schema,and I want to use http://<hostname>/pls/portal30/current_users to invoke the procedure but the IE return a "NOT FOUND" error .
I tried to create the procedure in scott schema,and use http://<hostname>/pls/scott/current_users to invoke the procedure ,it worked well.
The diffrent between DAD "scott" and "portal30" is the Authorization type,"scott" use basic auth,and "portal30" use sso.
anybody knows why it appeared?thanks.

Answer 1

Thanks , it works now .
But I still has a question,for example:
When I create a procedure to query what is the newest items be added in content area.
Let surppose there has two users:A and B,and I want userA to see 10 Items and userB to see
20 Items because of the diffrent privilege,how can I do it ?
Thanks again
