Logging out portal user programitically? (JSP)

Question

I am trying to log out users using a JSP. Here is a snippet of
code calling the wwsec_app_priv package. I am not having any
luck with this. Any suggestions?
Thanks,
Tom Henricksen
CallableStatement logout = null;
logout = con.prepareCall ("begin if wwctx_api.is_logged_on
then wwsec_app_priv.logout(p_done_url=>?); end if; end;");
logout.setString(1,logout_url);
logout.execute();
logout.close();

The syntax you have works within our current web page (PSP
page), but we have never tried it directly with PL/SQL.
One thing you might want to look at is that "normally" (from a
web page) the URL is called via the portal30 DAD:
/pls/portal30/PORTAL30.wwsec_app_priv.logout?p_done_url=
http%3A%2F%wherever.com
Could it be that this works if PORTAL30 is running the package,
and not the actual user? Just a wag. --Kate
